Executive Summary
Background
This report sets out the results of a project to compare and benchmark emissions from small petrol engines (less than 19 kilowatts) that are used to power outdoor garden equipment and were available for sale in Australia during 2006 The equipment powered by these small engines are used in lawnmowers brushcutters hedge trimmers and the like
These engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene
Sydneyrsquos Greater Metropolitan Region (GMR) annually records exceedances of the National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards The other jurisdictions meet or are close to meeting the current ozone standards
The Air NEPM standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds
The United States California Canada and Europe regulate emissions from outdoor equipment - the USA has had these in place since 1997 There are no Australian regulations or standards that limit air pollutant emissions from engines used in outdoor garden equipment however as the majority of equipment sold in Australia is imported some do comply with emission standards applicable to the country of origin
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars operated over a similar time These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit more than ten times the emissions of the best performers
iii
Based on estimates made using the National Pollutant Inventory database engines used in lawn mowers contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This is likely to rise to around 11 in the warmer spring and autumn weekends which is when lawns and other vegetation grows faster and when gardening is more popular The NPI does not take into account emissions from other types of powered outdoor equipment
The Australian Market
According to the Outdoor Power Equipment Association (OPEA) approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales with commercial garden services and government purchasing the rest
Indications are that sales of imported high polluting two stroke engines have increased over the last few years and it appears that the price of some powered garden equipment has dropped to the level where consumers regard them as disposables
An assessment of outdoor equipment on the Australian market found that the majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known However the industry estimate that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawn mower engine currently does not meet overseas emission limits for non-handheld equipment and Victa is undertaking research and development to reduce emissions from its two stroke engine to meet US and European standards
In spite of several attempts to obtain data on compliance with overseas emission standards from Australian distributors their response was poor The following figure therefore provides a best estimate of expected compliance of outdoor equipment on the Australian market with European CARB or USEPA requirements applicable in 2004

Measures to Increase Sales of Low Emission Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment engines in Australia These include
1 Maintaining the Status Quo
2 Government ndash Industry Partnership Program
3 Quasi regulation
4 Co-regulation
5 Regulations based on either a simple benchmark or tiered benchmarks
The Small Engine Expert Panel ndashOutdoor Equipment has considered in depth the most appropriate approach to take to improve the emissions performance of outdoor garden equipment sold in Australia It recommends the introduction of national regulations to control the emissions from outdoor garden equipment particularly in light of the increase in cheap imports onto the Australian market which although untested are considered very likely to have high emission levels The Expert Panel has developed some broad recommendation on which Australian regulations could be based which takes in consideration the local market and Victa These are summarised as follows
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines
v
The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment which should commence immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 20072008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) plus a phase-in period andor provisions for averaging banking and trading (ABT) of emissions over 2008-2012 to provide for early introduction of cleaner product
The US EPA Phase 1 and Phase two emissions limits are given in the table below
4 Walk-behind two stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications (to provide Victa time to develop a cleaner engine) Implementation timing is proposed to be the same as Recommendation 3 above
5 All products also to be certified to relevant EPA product durability categories
6 Subject to further review ABT if included may be phased out after 2012

Conclusion
From this review it is apparent that it is highly unlikely that the companies in the industry would engage in or commit to any voluntary type program It is therefore clear that the most expedient path to reduce emissions from these small engines is through national regulation State based regulations could only provide a piecemeal approach that would lead to product dumping in states where there are no regulations and inconsistent regulations that require industry to treat each state market differently In addition enforcement of any state based regulations would be a key problem due to existing Commonwealth and State Government mutual recognition legislation
While any national regulation of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulations optimum emissions reduction are potentially achievable by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment should be commenced

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles

USEPA emission limits for CO have not been included in this table (b) Includes useful life criteria of 50125300 hours

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

The US EPA is currently considering lsquoPhase 3rsquo regulations which are catalyst based standards to further reduce exhaust HC and NOx emissions from non handheld engines reduce evaporative HC and NOx emissions for both handheld and non handheld engines plus include extended durability criteria These limits are currently at discussion stage only They align with CARB Tier 3 but a longer lead time is proposed

CARB regulations first introduced emission limits for small engines manufactured from1995 The more recent schedule of emission limits are shown in Table 4 These limits depend solely on the engine capacity and apply to both handheld and non handheld classes

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label
10
Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

34 Europe
In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

13
The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

products in the Australian market The current project has obtained data for a total of 870 products or 72 of the estimated population In addition the sampling method is likely to be biased towards products with good environmental performance In these circumstances the following analysis should be regarded as indicative only
Survey results
The following tables and figures show expected compliance with European CARB or USEPA requirements based on the limited information provided by industry

42 Australian Sales of Outdoor Powered Equipment

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Figure 7 OPEA estimates of equipment sales in 2005-06 Note Blowervac is an industry term for equipment that combines blowing and vacuuming functions
Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment

The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012
34
7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments
4 Presentation by Dr Holger Lochmann Rob Baker Axel Rauch Stihl 19 April 2006
37
bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include

bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply

The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars
bull Some products may also be labelled with a Zero Star Rated label which indicates that the product is either not water efficient or does not meet basic performance requirements
bull A productrsquos water consumption figure
bull There are provisions for swing tags if there is inadequate surface area for label or the item is likely to be marked by sticking the label on the product
Summary Mandated product labelling using lsquostarrsquo rating system Has a disendorsement label and has provisions to ban products
33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists
Summary Website - voluntary but legislative base
4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)

Executive Summary
Background
This report sets out the results of a project to compare and benchmark emissions from small petrol engines (less than 19 kilowatts) that are used to power outdoor garden equipment and were available for sale in Australia during 2006 The equipment powered by these small engines are used in lawnmowers brushcutters hedge trimmers and the like
These engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene
Sydneyrsquos Greater Metropolitan Region (GMR) annually records exceedances of the National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards The other jurisdictions meet or are close to meeting the current ozone standards
The Air NEPM standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds
The United States California Canada and Europe regulate emissions from outdoor equipment - the USA has had these in place since 1997 There are no Australian regulations or standards that limit air pollutant emissions from engines used in outdoor garden equipment however as the majority of equipment sold in Australia is imported some do comply with emission standards applicable to the country of origin
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars operated over a similar time These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit more than ten times the emissions of the best performers
iii
Based on estimates made using the National Pollutant Inventory database engines used in lawn mowers contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This is likely to rise to around 11 in the warmer spring and autumn weekends which is when lawns and other vegetation grows faster and when gardening is more popular The NPI does not take into account emissions from other types of powered outdoor equipment
The Australian Market
According to the Outdoor Power Equipment Association (OPEA) approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales with commercial garden services and government purchasing the rest
Indications are that sales of imported high polluting two stroke engines have increased over the last few years and it appears that the price of some powered garden equipment has dropped to the level where consumers regard them as disposables
An assessment of outdoor equipment on the Australian market found that the majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known However the industry estimate that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawn mower engine currently does not meet overseas emission limits for non-handheld equipment and Victa is undertaking research and development to reduce emissions from its two stroke engine to meet US and European standards
In spite of several attempts to obtain data on compliance with overseas emission standards from Australian distributors their response was poor The following figure therefore provides a best estimate of expected compliance of outdoor equipment on the Australian market with European CARB or USEPA requirements applicable in 2004

Measures to Increase Sales of Low Emission Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment engines in Australia These include
1 Maintaining the Status Quo
2 Government ndash Industry Partnership Program
3 Quasi regulation
4 Co-regulation
5 Regulations based on either a simple benchmark or tiered benchmarks
The Small Engine Expert Panel ndashOutdoor Equipment has considered in depth the most appropriate approach to take to improve the emissions performance of outdoor garden equipment sold in Australia It recommends the introduction of national regulations to control the emissions from outdoor garden equipment particularly in light of the increase in cheap imports onto the Australian market which although untested are considered very likely to have high emission levels The Expert Panel has developed some broad recommendation on which Australian regulations could be based which takes in consideration the local market and Victa These are summarised as follows
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines
v
The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment which should commence immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 20072008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) plus a phase-in period andor provisions for averaging banking and trading (ABT) of emissions over 2008-2012 to provide for early introduction of cleaner product
The US EPA Phase 1 and Phase two emissions limits are given in the table below
4 Walk-behind two stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications (to provide Victa time to develop a cleaner engine) Implementation timing is proposed to be the same as Recommendation 3 above
5 All products also to be certified to relevant EPA product durability categories
6 Subject to further review ABT if included may be phased out after 2012

Conclusion
From this review it is apparent that it is highly unlikely that the companies in the industry would engage in or commit to any voluntary type program It is therefore clear that the most expedient path to reduce emissions from these small engines is through national regulation State based regulations could only provide a piecemeal approach that would lead to product dumping in states where there are no regulations and inconsistent regulations that require industry to treat each state market differently In addition enforcement of any state based regulations would be a key problem due to existing Commonwealth and State Government mutual recognition legislation
While any national regulation of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulations optimum emissions reduction are potentially achievable by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment should be commenced

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles
Table 2 US EPA Phase 2 Small Engine Emissions Standards (HC+NOx in gkW-hr) (a) (b)

USEPA emission limits for CO have not been included in this table (b) Includes useful life criteria of 50125300 hours

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

The US EPA is currently considering lsquoPhase 3rsquo regulations which are catalyst based standards to further reduce exhaust HC and NOx emissions from non handheld engines reduce evaporative HC and NOx emissions for both handheld and non handheld engines plus include extended durability criteria These limits are currently at discussion stage only They align with CARB Tier 3 but a longer lead time is proposed

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label
10
Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

34 Europe
In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Figure 7 OPEA estimates of equipment sales in 2005-06 Note Blowervac is an industry term for equipment that combines blowing and vacuuming functions
Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Trimmers 170 - 275 15-28
Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards
Emission Limits GkW-hr
Phase 1 (1997 ndash2001) Phase 2 (2007) HC NOx HC+NOx CO HC+NOx CO

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012

7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments

bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars
bull Some products may also be labelled with a Zero Star Rated label which indicates that the product is either not water efficient or does not meet basic performance requirements
bull A productrsquos water consumption figure
bull There are provisions for swing tags if there is inadequate surface area for label or the item is likely to be marked by sticking the label on the product
Summary Mandated product labelling using lsquostarrsquo rating system Has a disendorsement label and has provisions to ban products
33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists
Summary Website - voluntary but legislative base
4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)

Executive Summary
Background
This report sets out the results of a project to compare and benchmark emissions from small petrol engines (less than 19 kilowatts) that are used to power outdoor garden equipment and were available for sale in Australia during 2006 The equipment powered by these small engines are used in lawnmowers brushcutters hedge trimmers and the like
These engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene
Sydneyrsquos Greater Metropolitan Region (GMR) annually records exceedances of the National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards The other jurisdictions meet or are close to meeting the current ozone standards
The Air NEPM standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds
The United States California Canada and Europe regulate emissions from outdoor equipment - the USA has had these in place since 1997 There are no Australian regulations or standards that limit air pollutant emissions from engines used in outdoor garden equipment however as the majority of equipment sold in Australia is imported some do comply with emission standards applicable to the country of origin
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars operated over a similar time These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit more than ten times the emissions of the best performers
iii
Based on estimates made using the National Pollutant Inventory database engines used in lawn mowers contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This is likely to rise to around 11 in the warmer spring and autumn weekends which is when lawns and other vegetation grows faster and when gardening is more popular The NPI does not take into account emissions from other types of powered outdoor equipment
The Australian Market
According to the Outdoor Power Equipment Association (OPEA) approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales with commercial garden services and government purchasing the rest
Indications are that sales of imported high polluting two stroke engines have increased over the last few years and it appears that the price of some powered garden equipment has dropped to the level where consumers regard them as disposables
An assessment of outdoor equipment on the Australian market found that the majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known However the industry estimate that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawn mower engine currently does not meet overseas emission limits for non-handheld equipment and Victa is undertaking research and development to reduce emissions from its two stroke engine to meet US and European standards
In spite of several attempts to obtain data on compliance with overseas emission standards from Australian distributors their response was poor The following figure therefore provides a best estimate of expected compliance of outdoor equipment on the Australian market with European CARB or USEPA requirements applicable in 2004

Measures to Increase Sales of Low Emission Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment engines in Australia These include
1 Maintaining the Status Quo
2 Government ndash Industry Partnership Program
3 Quasi regulation
4 Co-regulation
5 Regulations based on either a simple benchmark or tiered benchmarks
The Small Engine Expert Panel ndashOutdoor Equipment has considered in depth the most appropriate approach to take to improve the emissions performance of outdoor garden equipment sold in Australia It recommends the introduction of national regulations to control the emissions from outdoor garden equipment particularly in light of the increase in cheap imports onto the Australian market which although untested are considered very likely to have high emission levels The Expert Panel has developed some broad recommendation on which Australian regulations could be based which takes in consideration the local market and Victa These are summarised as follows
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines
v
The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment which should commence immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 20072008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) plus a phase-in period andor provisions for averaging banking and trading (ABT) of emissions over 2008-2012 to provide for early introduction of cleaner product
The US EPA Phase 1 and Phase two emissions limits are given in the table below
4 Walk-behind two stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications (to provide Victa time to develop a cleaner engine) Implementation timing is proposed to be the same as Recommendation 3 above
5 All products also to be certified to relevant EPA product durability categories
6 Subject to further review ABT if included may be phased out after 2012

Conclusion
From this review it is apparent that it is highly unlikely that the companies in the industry would engage in or commit to any voluntary type program It is therefore clear that the most expedient path to reduce emissions from these small engines is through national regulation State based regulations could only provide a piecemeal approach that would lead to product dumping in states where there are no regulations and inconsistent regulations that require industry to treat each state market differently In addition enforcement of any state based regulations would be a key problem due to existing Commonwealth and State Government mutual recognition legislation
While any national regulation of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulations optimum emissions reduction are potentially achievable by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment should be commenced

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles

USEPA emission limits for CO have not been included in this table (b) Includes useful life criteria of 50125300 hours

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

The US EPA is currently considering lsquoPhase 3rsquo regulations which are catalyst based standards to further reduce exhaust HC and NOx emissions from non handheld engines reduce evaporative HC and NOx emissions for both handheld and non handheld engines plus include extended durability criteria These limits are currently at discussion stage only They align with CARB Tier 3 but a longer lead time is proposed

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label
10
Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

34 Europe
In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

products in the Australian market The current project has obtained data for a total of 870 products or 72 of the estimated population In addition the sampling method is likely to be biased towards products with good environmental performance In these circumstances the following analysis should be regarded as indicative only
Survey results
The following tables and figures show expected compliance with European CARB or USEPA requirements based on the limited information provided by industry

42 Australian Sales of Outdoor Powered Equipment

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Figure 7 OPEA estimates of equipment sales in 2005-06 Note Blowervac is an industry term for equipment that combines blowing and vacuuming functions
Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012

7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments
4 Presentation by Dr Holger Lochmann Rob Baker Axel Rauch Stihl 19 April 2006
37
bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars

33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists
Summary Website - voluntary but legislative base
4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)

Executive Summary
Background
This report sets out the results of a project to compare and benchmark emissions from small petrol engines (less than 19 kilowatts) that are used to power outdoor garden equipment and were available for sale in Australia during 2006 The equipment powered by these small engines are used in lawnmowers brushcutters hedge trimmers and the like
These engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene
Sydneyrsquos Greater Metropolitan Region (GMR) annually records exceedances of the National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards The other jurisdictions meet or are close to meeting the current ozone standards
The Air NEPM standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds
The United States California Canada and Europe regulate emissions from outdoor equipment - the USA has had these in place since 1997 There are no Australian regulations or standards that limit air pollutant emissions from engines used in outdoor garden equipment however as the majority of equipment sold in Australia is imported some do comply with emission standards applicable to the country of origin
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars operated over a similar time These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit more than ten times the emissions of the best performers
iii
Based on estimates made using the National Pollutant Inventory database engines used in lawn mowers contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This is likely to rise to around 11 in the warmer spring and autumn weekends which is when lawns and other vegetation grows faster and when gardening is more popular The NPI does not take into account emissions from other types of powered outdoor equipment
The Australian Market
According to the Outdoor Power Equipment Association (OPEA) approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales with commercial garden services and government purchasing the rest
Indications are that sales of imported high polluting two stroke engines have increased over the last few years and it appears that the price of some powered garden equipment has dropped to the level where consumers regard them as disposables
An assessment of outdoor equipment on the Australian market found that the majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known However the industry estimate that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawn mower engine currently does not meet overseas emission limits for non-handheld equipment and Victa is undertaking research and development to reduce emissions from its two stroke engine to meet US and European standards
In spite of several attempts to obtain data on compliance with overseas emission standards from Australian distributors their response was poor The following figure therefore provides a best estimate of expected compliance of outdoor equipment on the Australian market with European CARB or USEPA requirements applicable in 2004

Measures to Increase Sales of Low Emission Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment engines in Australia These include
1 Maintaining the Status Quo
2 Government ndash Industry Partnership Program
3 Quasi regulation
4 Co-regulation
5 Regulations based on either a simple benchmark or tiered benchmarks
The Small Engine Expert Panel ndashOutdoor Equipment has considered in depth the most appropriate approach to take to improve the emissions performance of outdoor garden equipment sold in Australia It recommends the introduction of national regulations to control the emissions from outdoor garden equipment particularly in light of the increase in cheap imports onto the Australian market which although untested are considered very likely to have high emission levels The Expert Panel has developed some broad recommendation on which Australian regulations could be based which takes in consideration the local market and Victa These are summarised as follows
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines
v
The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment which should commence immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 20072008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) plus a phase-in period andor provisions for averaging banking and trading (ABT) of emissions over 2008-2012 to provide for early introduction of cleaner product
The US EPA Phase 1 and Phase two emissions limits are given in the table below
4 Walk-behind two stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications (to provide Victa time to develop a cleaner engine) Implementation timing is proposed to be the same as Recommendation 3 above
5 All products also to be certified to relevant EPA product durability categories
6 Subject to further review ABT if included may be phased out after 2012

Conclusion
From this review it is apparent that it is highly unlikely that the companies in the industry would engage in or commit to any voluntary type program It is therefore clear that the most expedient path to reduce emissions from these small engines is through national regulation State based regulations could only provide a piecemeal approach that would lead to product dumping in states where there are no regulations and inconsistent regulations that require industry to treat each state market differently In addition enforcement of any state based regulations would be a key problem due to existing Commonwealth and State Government mutual recognition legislation
While any national regulation of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulations optimum emissions reduction are potentially achievable by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment should be commenced

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles
Table 2 US EPA Phase 2 Small Engine Emissions Standards (HC+NOx in gkW-hr) (a) (b)

USEPA emission limits for CO have not been included in this table (b) Includes useful life criteria of 50125300 hours

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

The US EPA is currently considering lsquoPhase 3rsquo regulations which are catalyst based standards to further reduce exhaust HC and NOx emissions from non handheld engines reduce evaporative HC and NOx emissions for both handheld and non handheld engines plus include extended durability criteria These limits are currently at discussion stage only They align with CARB Tier 3 but a longer lead time is proposed

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label
10
Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

34 Europe
In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards
Emission Limits GkW-hr
Phase 1 (1997 ndash2001) Phase 2 (2007) HC NOx HC+NOx CO HC+NOx CO

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012
34
7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments
4 Presentation by Dr Holger Lochmann Rob Baker Axel Rauch Stihl 19 April 2006
37
bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association

24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars
bull Some products may also be labelled with a Zero Star Rated label which indicates that the product is either not water efficient or does not meet basic performance requirements
bull A productrsquos water consumption figure
bull There are provisions for swing tags if there is inadequate surface area for label or the item is likely to be marked by sticking the label on the product
Summary Mandated product labelling using lsquostarrsquo rating system Has a disendorsement label and has provisions to ban products
33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists
Summary Website - voluntary but legislative base
4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)

Executive Summary
Background
This report sets out the results of a project to compare and benchmark emissions from small petrol engines (less than 19 kilowatts) that are used to power outdoor garden equipment and were available for sale in Australia during 2006 The equipment powered by these small engines are used in lawnmowers brushcutters hedge trimmers and the like
These engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene
Sydneyrsquos Greater Metropolitan Region (GMR) annually records exceedances of the National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards The other jurisdictions meet or are close to meeting the current ozone standards
The Air NEPM standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds
The United States California Canada and Europe regulate emissions from outdoor equipment - the USA has had these in place since 1997 There are no Australian regulations or standards that limit air pollutant emissions from engines used in outdoor garden equipment however as the majority of equipment sold in Australia is imported some do comply with emission standards applicable to the country of origin
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars operated over a similar time These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit more than ten times the emissions of the best performers
iii
Based on estimates made using the National Pollutant Inventory database engines used in lawn mowers contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This is likely to rise to around 11 in the warmer spring and autumn weekends which is when lawns and other vegetation grows faster and when gardening is more popular The NPI does not take into account emissions from other types of powered outdoor equipment
The Australian Market
According to the Outdoor Power Equipment Association (OPEA) approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales with commercial garden services and government purchasing the rest
Indications are that sales of imported high polluting two stroke engines have increased over the last few years and it appears that the price of some powered garden equipment has dropped to the level where consumers regard them as disposables
An assessment of outdoor equipment on the Australian market found that the majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known However the industry estimate that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawn mower engine currently does not meet overseas emission limits for non-handheld equipment and Victa is undertaking research and development to reduce emissions from its two stroke engine to meet US and European standards
In spite of several attempts to obtain data on compliance with overseas emission standards from Australian distributors their response was poor The following figure therefore provides a best estimate of expected compliance of outdoor equipment on the Australian market with European CARB or USEPA requirements applicable in 2004

Measures to Increase Sales of Low Emission Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment engines in Australia These include
1 Maintaining the Status Quo
2 Government ndash Industry Partnership Program
3 Quasi regulation
4 Co-regulation
5 Regulations based on either a simple benchmark or tiered benchmarks
The Small Engine Expert Panel ndashOutdoor Equipment has considered in depth the most appropriate approach to take to improve the emissions performance of outdoor garden equipment sold in Australia It recommends the introduction of national regulations to control the emissions from outdoor garden equipment particularly in light of the increase in cheap imports onto the Australian market which although untested are considered very likely to have high emission levels The Expert Panel has developed some broad recommendation on which Australian regulations could be based which takes in consideration the local market and Victa These are summarised as follows
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines
v
The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment which should commence immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 20072008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) plus a phase-in period andor provisions for averaging banking and trading (ABT) of emissions over 2008-2012 to provide for early introduction of cleaner product
The US EPA Phase 1 and Phase two emissions limits are given in the table below
4 Walk-behind two stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications (to provide Victa time to develop a cleaner engine) Implementation timing is proposed to be the same as Recommendation 3 above
5 All products also to be certified to relevant EPA product durability categories
6 Subject to further review ABT if included may be phased out after 2012

Conclusion
From this review it is apparent that it is highly unlikely that the companies in the industry would engage in or commit to any voluntary type program It is therefore clear that the most expedient path to reduce emissions from these small engines is through national regulation State based regulations could only provide a piecemeal approach that would lead to product dumping in states where there are no regulations and inconsistent regulations that require industry to treat each state market differently In addition enforcement of any state based regulations would be a key problem due to existing Commonwealth and State Government mutual recognition legislation
While any national regulation of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulations optimum emissions reduction are potentially achievable by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment should be commenced

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles

USEPA emission limits for CO have not been included in this table (b) Includes useful life criteria of 50125300 hours

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label

Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

42 Australian Sales of Outdoor Powered Equipment

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Figure 7 OPEA estimates of equipment sales in 2005-06 Note Blowervac is an industry term for equipment that combines blowing and vacuuming functions
Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment
26

Trimmers 170 - 275 15-28
Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers
29
6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012

7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments
4 Presentation by Dr Holger Lochmann Rob Baker Axel Rauch Stihl 19 April 2006
37
bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars
bull Some products may also be labelled with a Zero Star Rated label which indicates that the product is either not water efficient or does not meet basic performance requirements
bull A productrsquos water consumption figure
bull There are provisions for swing tags if there is inadequate surface area for label or the item is likely to be marked by sticking the label on the product
Summary Mandated product labelling using lsquostarrsquo rating system Has a disendorsement label and has provisions to ban products
33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

Source Real and Jones 2005
NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists

The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)

Executive Summary
Background
This report sets out the results of a project to compare and benchmark emissions from small petrol engines (less than 19 kilowatts) that are used to power outdoor garden equipment and were available for sale in Australia during 2006 The equipment powered by these small engines are used in lawnmowers brushcutters hedge trimmers and the like
These engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene
Sydneyrsquos Greater Metropolitan Region (GMR) annually records exceedances of the National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards The other jurisdictions meet or are close to meeting the current ozone standards
The Air NEPM standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds
The United States California Canada and Europe regulate emissions from outdoor equipment - the USA has had these in place since 1997 There are no Australian regulations or standards that limit air pollutant emissions from engines used in outdoor garden equipment however as the majority of equipment sold in Australia is imported some do comply with emission standards applicable to the country of origin
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars operated over a similar time These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit more than ten times the emissions of the best performers
iii
Based on estimates made using the National Pollutant Inventory database engines used in lawn mowers contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This is likely to rise to around 11 in the warmer spring and autumn weekends which is when lawns and other vegetation grows faster and when gardening is more popular The NPI does not take into account emissions from other types of powered outdoor equipment
The Australian Market
According to the Outdoor Power Equipment Association (OPEA) approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales with commercial garden services and government purchasing the rest
Indications are that sales of imported high polluting two stroke engines have increased over the last few years and it appears that the price of some powered garden equipment has dropped to the level where consumers regard them as disposables
An assessment of outdoor equipment on the Australian market found that the majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known However the industry estimate that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawn mower engine currently does not meet overseas emission limits for non-handheld equipment and Victa is undertaking research and development to reduce emissions from its two stroke engine to meet US and European standards
In spite of several attempts to obtain data on compliance with overseas emission standards from Australian distributors their response was poor The following figure therefore provides a best estimate of expected compliance of outdoor equipment on the Australian market with European CARB or USEPA requirements applicable in 2004

Measures to Increase Sales of Low Emission Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment engines in Australia These include
1 Maintaining the Status Quo
2 Government ndash Industry Partnership Program
3 Quasi regulation
4 Co-regulation
5 Regulations based on either a simple benchmark or tiered benchmarks
The Small Engine Expert Panel ndashOutdoor Equipment has considered in depth the most appropriate approach to take to improve the emissions performance of outdoor garden equipment sold in Australia It recommends the introduction of national regulations to control the emissions from outdoor garden equipment particularly in light of the increase in cheap imports onto the Australian market which although untested are considered very likely to have high emission levels The Expert Panel has developed some broad recommendation on which Australian regulations could be based which takes in consideration the local market and Victa These are summarised as follows
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines
v
The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment which should commence immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 20072008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) plus a phase-in period andor provisions for averaging banking and trading (ABT) of emissions over 2008-2012 to provide for early introduction of cleaner product
The US EPA Phase 1 and Phase two emissions limits are given in the table below
4 Walk-behind two stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications (to provide Victa time to develop a cleaner engine) Implementation timing is proposed to be the same as Recommendation 3 above
5 All products also to be certified to relevant EPA product durability categories
6 Subject to further review ABT if included may be phased out after 2012

Conclusion
From this review it is apparent that it is highly unlikely that the companies in the industry would engage in or commit to any voluntary type program It is therefore clear that the most expedient path to reduce emissions from these small engines is through national regulation State based regulations could only provide a piecemeal approach that would lead to product dumping in states where there are no regulations and inconsistent regulations that require industry to treat each state market differently In addition enforcement of any state based regulations would be a key problem due to existing Commonwealth and State Government mutual recognition legislation
While any national regulation of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulations optimum emissions reduction are potentially achievable by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment should be commenced

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label
10
Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

34 Europe
In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Figure 7 OPEA estimates of equipment sales in 2005-06 Note Blowervac is an industry term for equipment that combines blowing and vacuuming functions
Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards
Emission Limits GkW-hr
Phase 1 (1997 ndash2001) Phase 2 (2007) HC NOx HC+NOx CO HC+NOx CO
Non-handheld I-A lt66cc 161 610 I-B 66-lt100cc 161 610 I 100-225 cm3 161 519 161 610 II 225 cm3 134 519 121 610 Handheld III lt20 cm3 295 536 805 50 805 IV 20-50 cm3 241 536 805 50 805 V 50 cm3 161 536 603 72 603
Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012
34
7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments
4 Presentation by Dr Holger Lochmann Rob Baker Axel Rauch Stihl 19 April 2006
37
bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters

77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)

Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars
bull Some products may also be labelled with a Zero Star Rated label which indicates that the product is either not water efficient or does not meet basic performance requirements
bull A productrsquos water consumption figure
bull There are provisions for swing tags if there is inadequate surface area for label or the item is likely to be marked by sticking the label on the product
Summary Mandated product labelling using lsquostarrsquo rating system Has a disendorsement label and has provisions to ban products
33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists
Summary Website - voluntary but legislative base
4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)

Executive Summary
Background
This report sets out the results of a project to compare and benchmark emissions from small petrol engines (less than 19 kilowatts) that are used to power outdoor garden equipment and were available for sale in Australia during 2006 The equipment powered by these small engines are used in lawnmowers brushcutters hedge trimmers and the like
These engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene
Sydneyrsquos Greater Metropolitan Region (GMR) annually records exceedances of the National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards The other jurisdictions meet or are close to meeting the current ozone standards
The Air NEPM standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds
The United States California Canada and Europe regulate emissions from outdoor equipment - the USA has had these in place since 1997 There are no Australian regulations or standards that limit air pollutant emissions from engines used in outdoor garden equipment however as the majority of equipment sold in Australia is imported some do comply with emission standards applicable to the country of origin
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars operated over a similar time These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit more than ten times the emissions of the best performers
iii
Based on estimates made using the National Pollutant Inventory database engines used in lawn mowers contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This is likely to rise to around 11 in the warmer spring and autumn weekends which is when lawns and other vegetation grows faster and when gardening is more popular The NPI does not take into account emissions from other types of powered outdoor equipment
The Australian Market
According to the Outdoor Power Equipment Association (OPEA) approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales with commercial garden services and government purchasing the rest
Indications are that sales of imported high polluting two stroke engines have increased over the last few years and it appears that the price of some powered garden equipment has dropped to the level where consumers regard them as disposables
An assessment of outdoor equipment on the Australian market found that the majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known However the industry estimate that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawn mower engine currently does not meet overseas emission limits for non-handheld equipment and Victa is undertaking research and development to reduce emissions from its two stroke engine to meet US and European standards
In spite of several attempts to obtain data on compliance with overseas emission standards from Australian distributors their response was poor The following figure therefore provides a best estimate of expected compliance of outdoor equipment on the Australian market with European CARB or USEPA requirements applicable in 2004
iv

Measures to Increase Sales of Low Emission Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment engines in Australia These include
1 Maintaining the Status Quo
2 Government ndash Industry Partnership Program
3 Quasi regulation
4 Co-regulation
5 Regulations based on either a simple benchmark or tiered benchmarks
The Small Engine Expert Panel ndashOutdoor Equipment has considered in depth the most appropriate approach to take to improve the emissions performance of outdoor garden equipment sold in Australia It recommends the introduction of national regulations to control the emissions from outdoor garden equipment particularly in light of the increase in cheap imports onto the Australian market which although untested are considered very likely to have high emission levels The Expert Panel has developed some broad recommendation on which Australian regulations could be based which takes in consideration the local market and Victa These are summarised as follows
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines
v
The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment which should commence immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 20072008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) plus a phase-in period andor provisions for averaging banking and trading (ABT) of emissions over 2008-2012 to provide for early introduction of cleaner product
The US EPA Phase 1 and Phase two emissions limits are given in the table below
4 Walk-behind two stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications (to provide Victa time to develop a cleaner engine) Implementation timing is proposed to be the same as Recommendation 3 above
5 All products also to be certified to relevant EPA product durability categories
6 Subject to further review ABT if included may be phased out after 2012

Conclusion
From this review it is apparent that it is highly unlikely that the companies in the industry would engage in or commit to any voluntary type program It is therefore clear that the most expedient path to reduce emissions from these small engines is through national regulation State based regulations could only provide a piecemeal approach that would lead to product dumping in states where there are no regulations and inconsistent regulations that require industry to treat each state market differently In addition enforcement of any state based regulations would be a key problem due to existing Commonwealth and State Government mutual recognition legislation
While any national regulation of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulations optimum emissions reduction are potentially achievable by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment should be commenced

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles
Table 2 US EPA Phase 2 Small Engine Emissions Standards (HC+NOx in gkW-hr) (a) (b)

USEPA emission limits for CO have not been included in this table (b) Includes useful life criteria of 50125300 hours

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

The US EPA is currently considering lsquoPhase 3rsquo regulations which are catalyst based standards to further reduce exhaust HC and NOx emissions from non handheld engines reduce evaporative HC and NOx emissions for both handheld and non handheld engines plus include extended durability criteria These limits are currently at discussion stage only They align with CARB Tier 3 but a longer lead time is proposed

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label
10
Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

34 Europe
In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Trimmers 170 - 275 15-28
Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards
Emission Limits GkW-hr
Phase 1 (1997 ndash2001) Phase 2 (2007) HC NOx HC+NOx CO HC+NOx CO

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012
34
7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments

bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars
bull Some products may also be labelled with a Zero Star Rated label which indicates that the product is either not water efficient or does not meet basic performance requirements
bull A productrsquos water consumption figure
bull There are provisions for swing tags if there is inadequate surface area for label or the item is likely to be marked by sticking the label on the product
Summary Mandated product labelling using lsquostarrsquo rating system Has a disendorsement label and has provisions to ban products
33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists
Summary Website - voluntary but legislative base
4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)
72
Based on estimates made using the National Pollutant Inventory database engines used in lawn mowers contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This is likely to rise to around 11 in the warmer spring and autumn weekends which is when lawns and other vegetation grows faster and when gardening is more popular The NPI does not take into account emissions from other types of powered outdoor equipment
The Australian Market
According to the Outdoor Power Equipment Association (OPEA) approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales with commercial garden services and government purchasing the rest
Indications are that sales of imported high polluting two stroke engines have increased over the last few years and it appears that the price of some powered garden equipment has dropped to the level where consumers regard them as disposables
An assessment of outdoor equipment on the Australian market found that the majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known However the industry estimate that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawn mower engine currently does not meet overseas emission limits for non-handheld equipment and Victa is undertaking research and development to reduce emissions from its two stroke engine to meet US and European standards
In spite of several attempts to obtain data on compliance with overseas emission standards from Australian distributors their response was poor The following figure therefore provides a best estimate of expected compliance of outdoor equipment on the Australian market with European CARB or USEPA requirements applicable in 2004
iv

Measures to Increase Sales of Low Emission Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment engines in Australia These include
1 Maintaining the Status Quo
2 Government ndash Industry Partnership Program
3 Quasi regulation
4 Co-regulation
5 Regulations based on either a simple benchmark or tiered benchmarks
The Small Engine Expert Panel ndashOutdoor Equipment has considered in depth the most appropriate approach to take to improve the emissions performance of outdoor garden equipment sold in Australia It recommends the introduction of national regulations to control the emissions from outdoor garden equipment particularly in light of the increase in cheap imports onto the Australian market which although untested are considered very likely to have high emission levels The Expert Panel has developed some broad recommendation on which Australian regulations could be based which takes in consideration the local market and Victa These are summarised as follows
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines
v
The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment which should commence immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 20072008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) plus a phase-in period andor provisions for averaging banking and trading (ABT) of emissions over 2008-2012 to provide for early introduction of cleaner product
The US EPA Phase 1 and Phase two emissions limits are given in the table below
4 Walk-behind two stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications (to provide Victa time to develop a cleaner engine) Implementation timing is proposed to be the same as Recommendation 3 above
5 All products also to be certified to relevant EPA product durability categories
6 Subject to further review ABT if included may be phased out after 2012

Conclusion
From this review it is apparent that it is highly unlikely that the companies in the industry would engage in or commit to any voluntary type program It is therefore clear that the most expedient path to reduce emissions from these small engines is through national regulation State based regulations could only provide a piecemeal approach that would lead to product dumping in states where there are no regulations and inconsistent regulations that require industry to treat each state market differently In addition enforcement of any state based regulations would be a key problem due to existing Commonwealth and State Government mutual recognition legislation
While any national regulation of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulations optimum emissions reduction are potentially achievable by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment should be commenced

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles

USEPA emission limits for CO have not been included in this table (b) Includes useful life criteria of 50125300 hours

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label

Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

42 Australian Sales of Outdoor Powered Equipment

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Figure 7 OPEA estimates of equipment sales in 2005-06 Note Blowervac is an industry term for equipment that combines blowing and vacuuming functions
Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Trimmers 170 - 275 15-28
Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012

7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments

37
bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars
bull Some products may also be labelled with a Zero Star Rated label which indicates that the product is either not water efficient or does not meet basic performance requirements
bull A productrsquos water consumption figure
bull There are provisions for swing tags if there is inadequate surface area for label or the item is likely to be marked by sticking the label on the product
Summary Mandated product labelling using lsquostarrsquo rating system Has a disendorsement label and has provisions to ban products
33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

Source Real and Jones 2005
NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists
Summary Website - voluntary but legislative base
4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)

Measures to Increase Sales of Low Emission Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment engines in Australia These include
1 Maintaining the Status Quo
2 Government ndash Industry Partnership Program
3 Quasi regulation
4 Co-regulation
5 Regulations based on either a simple benchmark or tiered benchmarks
The Small Engine Expert Panel ndashOutdoor Equipment has considered in depth the most appropriate approach to take to improve the emissions performance of outdoor garden equipment sold in Australia It recommends the introduction of national regulations to control the emissions from outdoor garden equipment particularly in light of the increase in cheap imports onto the Australian market which although untested are considered very likely to have high emission levels The Expert Panel has developed some broad recommendation on which Australian regulations could be based which takes in consideration the local market and Victa These are summarised as follows
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines
v
The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment which should commence immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 20072008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) plus a phase-in period andor provisions for averaging banking and trading (ABT) of emissions over 2008-2012 to provide for early introduction of cleaner product
The US EPA Phase 1 and Phase two emissions limits are given in the table below
4 Walk-behind two stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications (to provide Victa time to develop a cleaner engine) Implementation timing is proposed to be the same as Recommendation 3 above
5 All products also to be certified to relevant EPA product durability categories
6 Subject to further review ABT if included may be phased out after 2012

Conclusion
From this review it is apparent that it is highly unlikely that the companies in the industry would engage in or commit to any voluntary type program It is therefore clear that the most expedient path to reduce emissions from these small engines is through national regulation State based regulations could only provide a piecemeal approach that would lead to product dumping in states where there are no regulations and inconsistent regulations that require industry to treat each state market differently In addition enforcement of any state based regulations would be a key problem due to existing Commonwealth and State Government mutual recognition legislation
While any national regulation of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulations optimum emissions reduction are potentially achievable by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment should be commenced

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles

USEPA emission limits for CO have not been included in this table (b) Includes useful life criteria of 50125300 hours

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

The US EPA is currently considering lsquoPhase 3rsquo regulations which are catalyst based standards to further reduce exhaust HC and NOx emissions from non handheld engines reduce evaporative HC and NOx emissions for both handheld and non handheld engines plus include extended durability criteria These limits are currently at discussion stage only They align with CARB Tier 3 but a longer lead time is proposed

Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

42 Australian Sales of Outdoor Powered Equipment

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Figure 7 OPEA estimates of equipment sales in 2005-06 Note Blowervac is an industry term for equipment that combines blowing and vacuuming functions
Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Trimmers 170 - 275 15-28
Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012

7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments
4 Presentation by Dr Holger Lochmann Rob Baker Axel Rauch Stihl 19 April 2006
37
bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars
bull Some products may also be labelled with a Zero Star Rated label which indicates that the product is either not water efficient or does not meet basic performance requirements
bull A productrsquos water consumption figure
bull There are provisions for swing tags if there is inadequate surface area for label or the item is likely to be marked by sticking the label on the product
Summary Mandated product labelling using lsquostarrsquo rating system Has a disendorsement label and has provisions to ban products
33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

Source Real and Jones 2005
NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists

4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)

The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment which should commence immediately

(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) plus a phase-in period andor provisions for averaging banking and trading (ABT) of emissions over 2008-2012 to provide for early introduction of cleaner product
The US EPA Phase 1 and Phase two emissions limits are given in the table below

Conclusion
From this review it is apparent that it is highly unlikely that the companies in the industry would engage in or commit to any voluntary type program It is therefore clear that the most expedient path to reduce emissions from these small engines is through national regulation State based regulations could only provide a piecemeal approach that would lead to product dumping in states where there are no regulations and inconsistent regulations that require industry to treat each state market differently In addition enforcement of any state based regulations would be a key problem due to existing Commonwealth and State Government mutual recognition legislation
While any national regulation of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulations optimum emissions reduction are potentially achievable by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment should be commenced

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles

USEPA emission limits for CO have not been included in this table (b) Includes useful life criteria of 50125300 hours

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

The US EPA is currently considering lsquoPhase 3rsquo regulations which are catalyst based standards to further reduce exhaust HC and NOx emissions from non handheld engines reduce evaporative HC and NOx emissions for both handheld and non handheld engines plus include extended durability criteria These limits are currently at discussion stage only They align with CARB Tier 3 but a longer lead time is proposed

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label

Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

34 Europe
In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

13
The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

products in the Australian market The current project has obtained data for a total of 870 products or 72 of the estimated population In addition the sampling method is likely to be biased towards products with good environmental performance In these circumstances the following analysis should be regarded as indicative only
Survey results
The following tables and figures show expected compliance with European CARB or USEPA requirements based on the limited information provided by industry

42 Australian Sales of Outdoor Powered Equipment

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Figure 7 OPEA estimates of equipment sales in 2005-06 Note Blowervac is an industry term for equipment that combines blowing and vacuuming functions
Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012

7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments
4 Presentation by Dr Holger Lochmann Rob Baker Axel Rauch Stihl 19 April 2006
37
bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars

33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists
Summary Website - voluntary but legislative base
4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)
72
Conclusion
From this review it is apparent that it is highly unlikely that the companies in the industry would engage in or commit to any voluntary type program It is therefore clear that the most expedient path to reduce emissions from these small engines is through national regulation State based regulations could only provide a piecemeal approach that would lead to product dumping in states where there are no regulations and inconsistent regulations that require industry to treat each state market differently In addition enforcement of any state based regulations would be a key problem due to existing Commonwealth and State Government mutual recognition legislation
While any national regulation of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulations optimum emissions reduction are potentially achievable by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating two and four stroke lawn mowers and handheld power equipment should be commenced

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles

USEPA emission limits for CO have not been included in this table (b) Includes useful life criteria of 50125300 hours

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)

The US EPA is currently considering lsquoPhase 3rsquo regulations which are catalyst based standards to further reduce exhaust HC and NOx emissions from non handheld engines reduce evaporative HC and NOx emissions for both handheld and non handheld engines plus include extended durability criteria These limits are currently at discussion stage only They align with CARB Tier 3 but a longer lead time is proposed

CARB regulations first introduced emission limits for small engines manufactured from1995 The more recent schedule of emission limits are shown in Table 4 These limits depend solely on the engine capacity and apply to both handheld and non handheld classes

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label
10
Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

34 Europe
In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards
Emission Limits GkW-hr
Phase 1 (1997 ndash2001) Phase 2 (2007) HC NOx HC+NOx CO HC+NOx CO

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012
34
7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments
4 Presentation by Dr Holger Lochmann Rob Baker Axel Rauch Stihl 19 April 2006
37
bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars
bull Some products may also be labelled with a Zero Star Rated label which indicates that the product is either not water efficient or does not meet basic performance requirements
bull A productrsquos water consumption figure
bull There are provisions for swing tags if there is inadequate surface area for label or the item is likely to be marked by sticking the label on the product
Summary Mandated product labelling using lsquostarrsquo rating system Has a disendorsement label and has provisions to ban products
33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists
Summary Website - voluntary but legislative base
4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)

1 Introduction
This report sets out the results of a project to compare and benchmark emissions from engines used in outdoor garden equipment that were available for sale in Australia during 2006 Possible outcomes from the project range from consumer guidelines for selecting low emission engines to regulatory controls on emissions There are currently no state or national regulations that directly control emissions from these engines
The project was commissioned by the Commonwealth Department of the Environment and Water Resources on behalf of state and territory government departments working on reducing the impacts of small engine emissions This report was prepared in consultation with an Expert Panel that included representatives from the Outdoor Power Equipment Association (OPEA)
11 Emissions from outdoor garden equipment engines
Small engines particularly conventional two stroke engines used in applications such as outdoor garden equipment are high polluters relative to their engine size and usage1 These small engines emit volatile organic compounds (VOCs) and oxides of nitrogen (NOx) which contribute to ozone (photochemical smog) formation in summer They also emit particles carbon monoxide (CO) and a range of air toxics such as benzene The USA California Canada and Europe and regulate emissions of VOCs NOx carbon monoxide and particle emissions from outdoor garden equipment
There are five types of spark-ignition engines that can be used in outdoor garden equipment
bull two stroke with carburettor (2c)
bull two stroke with pre-chamber fuel injection (2i)
bull two stroke with direct fuel injection (2di)
bull four stroke with carburettor (4c)
bull four stroke with fuel injection (4i) (includes direct injection)
Carburettor and pre-chamber fuel injection two stroke engines are inherently more polluting than the other three types This is due to their inability to completely separate the inlet gases from the exhaust gases resulting in up to 30 of the fuel being left unburnt and the need to add oil to the fuel to lubricate the engine (four stroke engines have separate reservoirs for fuel and oil) However twostroke carburettor engines typically weigh less than a four stroke engine of the same power and this tends to make them attractive for handheld equipment They also tend to have fewer components are generally cheaper to purchase and are cheaper to maintain than
1 Outdoor equipment covered in this report are engines less than 19kW

four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

The US EPA is currently considering lsquoPhase 3rsquo regulations which are catalyst based standards to further reduce exhaust HC and NOx emissions from non handheld engines reduce evaporative HC and NOx emissions for both handheld and non handheld engines plus include extended durability criteria These limits are currently at discussion stage only They align with CARB Tier 3 but a longer lead time is proposed

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label
10
Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

34 Europe
In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards
Emission Limits GkW-hr
Phase 1 (1997 ndash2001) Phase 2 (2007) HC NOx HC+NOx CO HC+NOx CO

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012
34
7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments
4 Presentation by Dr Holger Lochmann Rob Baker Axel Rauch Stihl 19 April 2006
37
bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars
bull Some products may also be labelled with a Zero Star Rated label which indicates that the product is either not water efficient or does not meet basic performance requirements
bull A productrsquos water consumption figure
bull There are provisions for swing tags if there is inadequate surface area for label or the item is likely to be marked by sticking the label on the product
Summary Mandated product labelling using lsquostarrsquo rating system Has a disendorsement label and has provisions to ban products
33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists
Summary Website - voluntary but legislative base
4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)
72
four stroke motors Victa Lawncare is currently undertaking research and development to improve the environmental performance of two stroke carburettors and while some emission improvements have been made a two stroke compliant with US or European standards is still considered several years away
Four stroke carburettor engines are generally quieter more fuel efficient and are less polluting than conventional two stroke engines
Direct fuel injection (dfi) either two stroke or four stroke overcomes the unburnt fuel problem and can meet the stringent regulated exhaust emission limits that apply overseas However there is not any evidence that dfi engines are being used in outdoor garden equipment available in Australia It appears that engines used in outdoor garden equipment in Australia are generally restricted to two and four stroke carburettor engines
Small engines are not as advanced in environmental terms as motor vehicle engines As a result even the better-performing small engines emit far greater quantities of pollutants per hour than typical modern car engines For example the US Environmental Protection Agency (USEPA) 2002 limit for a typical 4 kilowatt (kW) lawnmower motor is about 66 grams (g) of regulated pollutants per hour of operation A typical 08kW brushcutter sold new in 2002 emitted about 160grams of pollutants per hour - reducing to 40grams per hour if bought new in 2006 The equivalent limit for cars under Australian Design Rule 79 is about 16g per hour In other words operated over a similar time one hour of operation of a brushcutter that meets USEPA 2002 limits produces the same pollution as ten cars and a 4kW lawnmower the same pollution as four cars These comparisons are subject to differences in test methods but they do provide an indication of the disproportionate amount of pollution emitted by small engines
Engines that do not comply with current USEPA requirements are likely to emit several times the amount of pollution calculated in the above example Therefore the worst performing engines are likely to emit some ten times the emissions of the best performers
Because of the combustion of oil these engines also emit high levels of particles Although small engines only contribute a small amount to total particle emissions the rate of particle release compared to other engines can be very high For example lawnmowers can emit over 10 times more particles (in terms of grams per hour) than a petrol motor vehicle (manufactured between 1994 and 2001)
All the above emission comparisons between outdoor garden equipment engines and motor vehicles are subject to differences in test methods but they indicate the disproportionate amount of pollution emitted by small garden equipment engines It also needs to be recognised that motor vehicles in Australia average more than 15000 kilometres per year (ABS 2003) while the annual average use of outdoor garden equipment is around 25 hours for a lawnmower and less for other types of equipment Commercial operators however are likely to have a much higher usage rates than the general public

This paper examines the Australian market for small engines used in lawnmowers and handheld garden equipment their impact on air quality relevant overseas regulations and their applicability to Australia and makes recommendations to reduce air quality impacts from these engines
A wide range of information sources has been referenced for this report including data and information supplied by manufacturers distributors and dealers in small engines

2 Air Quality and Outdoor Garden Equipment Engines
Emission inventories make estimates of emissions of substances from a multitude of sources into airsheds The National Pollutant Inventory (NPI) which is run cooperatively by the Australian state and territory governments contains data on 90 substances that are emitted to the Australian environment The substances included in the NPI have been identified as important because of their possible health and environmental effects Industry facilities estimate their own emissions annually and report to states and territories Non-industry (or diffuse) emissions estimates which includes emissions from outdoor garden equipment are made by the states and territories on a periodic basis using information sources such as surveys databases and sales figures
The NPI only reports emissions from domestic lawn mowing and for a few airsheds the contribution made by public open space lawn mowing It does not report on the contribution made by other types of outdoor garden equipment such as brushcutters National and selected state NPI emissions estimates for the common air pollutants and for Air Toxics NEPM pollutants from domestic lawn mowing are summarised in Table 1 It should be noted that national emissions from lawn mowing are underestimates as the NPI records emissions for major airsheds only and therefore is not Australia wide plus the estimates do not include evaporative emissions from fuel tanks and hoses
This NPI data is indicative only as the accuracy and completeness of the data sets varies across airsheds and is reliant on the estimation techniques used For example while the population in the NSW is higher than other airsheds its emissions look disproportionally high when compared to the other airsheds This could be because the estimation technique varies or it is due to some other factor

Analysis of the NPI database at the national level shows that domestic lawn mowing is the
- Fourth largest source of benzene contributing 7 to the total reported airshed load
- Fourth largest source of formaldehyde contributing 3 to the total reported airshed load
- Fifth largest source of xylene contributing 6 to the total reported airshed load
- Fifth largest source of toluene contributing 6 to the total reported airshed load
- Sixth largest source of carbon monoxide contributing 12 to the total reported airshed load
- Ninth largest source of VOCs contributing 3 to the total reported airshed load when biogenics (natural sources such as trees and soil) are excluded
The NSW Department of Environment and Conservation has been upgrading its emissions inventory Based on 2003 emissions data non-road anthropogenic sources

contribute 619 of the VOCs to the GMR airshed Preliminary results2 indicate that VOC emissions from domestic and public open space lawn mowing contributes on an annual average 41 of all VOC emissions in the GMR On a typical weekend during warmer weather this percentage rises to 11
Therefore it could be assumed that lawn mowing could contribute approximately 4 on average to VOC emissions from anthropogenic sources in major airsheds in Australia when public open space lawn mowing is included This percentage is likely to rise significantly in the warmer spring and autumn weekends which is when lawns and other vegetation grow faster and when more people garden
21 Air Quality Standards
In June 1998 the National Environment Protection Measure for Ambient Air (Air NEPM) established national uniform standards for ambient air quality for the six most common air pollutants ndash carbon monoxide nitrogen dioxide photochemical oxidants (measured as ozone) sulfur dioxide lead and particles less than 10 microns (PM10) The NEPM was varied in 2003 to include PM25 advisory reporting standards and in April 2004 a National Environment Protection Measure for Air Toxics was adopted
Nationally the common pollutants of most concern (particularly in major urban areas) are fine particles and ground level photochemical smog (measured as ozone) which is formed in the warmer months when volatile organic compounds (VOCs) and oxides of nitrogen (NOx) react in the atmosphere under the influence of sunlight in a series of chemical reactions
Recent health studies (cited in NEPC 2005) have strengthened the evidence that there are short-term ozone effects on mortality and respiratory disease The studies also strengthen the view that there does not appear to be a threshold for ozone below which no effects on health are expected to occur In recent years Australian epidemiological studies have been conducted which confirm the results of overseas studies that there is a relationship between elevated ozone levels and hospitalisations and deaths from certain conditions
There are two national ozone standards a one hour standard of 010ppm and a four hour standard of 008ppm with a goal that allows for one exceedance per year by 2008 Sydney experiences a number of days each year of ozone levels above these standards In 2003 Sydney exceeded the one hour standard on 11 days in 2003 19 days in 2004 and 9 days in 2005 The four hour standard was exceeded on 13 days in 2003 19 days in 2004 and 13 days in 2005 Further reductions in VOC and NOx emissions are needed to reduce ozone concentrations in Sydney to levels that would comply with the Air NEPM
The other jurisdictions meet or are close to meeting the current National Environment Protection (Ambient Air Quality) Measure (Air NEPM) ozone standards (NEPC 2005) However the ozone standards are being reviewed and based on current human health evidence the argument appears to be strengthening for tighter ozone standards
2 Presentation to Expert Panel 27 April 2006 by Nick Agipades Manager Major Air Projects NSW DEC

Should a stricter standard or an eight-hour standard consistent with international standardsguidelines be adopted achievability of Air NEPM ozone standards or goals could become an issue for some of the other major urban airsheds (NEPC 2005)
Modeling of ozone for Sydneyrsquos Greater Metropolitan Region (GMR) indicates that the implementation of Euro emission limits for on-road vehicles and hence the increased presence of these less polluting vehicles in the fleet and retirement of old more polluting vehicles from the fleet is not sufficient to meet the current NEPM goals Modeling suggests that very large reductions in precursor emissions would be required to meet the current ozone one hour goal (NEPC 2005)
Even when the effects of bushfires and when hazard reduction burning are taken into consideration airsheds such as Launceston Melbourne and Sydney struggle to meet the national standards for particles (EPA 2006) However outdoor powered equipment predominantly from two stroke engines makes only a minor contribution to ambient fine particle loads
While carbon monoxide emissions from engines used in outdoor garden equipment are regulated overseas air monitoring in Australia indicates that carbon monoxides levels are well below the national air quality standards and there are no pressing issues requiring CO from outdoor powered equipment to be regulated In addition data indicates that lowering emissions of VOCs and NOx from small engines reduces CO emissions
Many of the pollutant sources which contribute to the formation of ozone and to particle levels also contain air toxics such as benzene toluene formaldehyde and xylenes These air toxics have been shown to be responsible for a range of health problems including asthma respiratory illnesses and cancer The National Environment Protection Measure for Air Toxics requires each jurisdiction to monitor and report annually on five air toxics benzene polycyclic aromatic hydrocarbons formaldehyde toluene and xylenes The monitoring data is intended to inform future policy and also the public on ambient levels of these air pollutants Monitoring of air toxics to date shows that levels are low and below the national monitoring investigation levels (EPA Vic 2006 DEC 2006)

3 Emission Standards for Small Engines
31 Australia
At present there are no Australian regulations or standards to limit air pollutant emissions from small (two and four stroke) engines Australia does benefit to some extent from overseas regulations as many lawnmowers and other gardening equipment sold in Australia have engines manufactured in the United States or Europe where strict standards apply
32 United States
In the United States emission regulations set by the United States Environmental Protection Agency (USEPA) and the Californian Air Resources Board (CARB) apply to lawn mowers and other powered gardening equipment Although CARB standards currently tend to be stricter than USEPA standards by 2006 emissions limits applying under the two standards will be very similar
United States Environment Protection Agency (US EPA)
In 1995 the USEPA introduced ldquoPhase 1rdquo regulations covering small non-road engines with a power of not more than 19kW (25HP) The regulations applied to equipment manufactured from 1997
These regulations have seven classes of equipment based on portability and engine displacement volume (ldquocapacityrdquo) In March 2000 the USEPA published ldquoPhase 2rdquo regulations which are shown in Table 2 These set limits for combined emissions of hydrocarbons (HC) and oxides of nitrogen (NOx) and separate limits for carbon monoxide (CO) emissions and for two stroke engines only particles

USEPA emission limits for CO have not been included in this table (b) Includes useful life criteria of 50125300 hours

When the USEPA introduced ldquoPhase 2rdquo regulations it included averaging banking and trading provisions (ABT) which were seen ldquoas an important element in making stringent Phase 2 emissions standards achievable with regard to technological feasibility lead time and costrdquo (USA 1999) The USEPA also claimed (USA 2000) that the ABT program secures early emissions benefits through the early introduction of cleaner engines
ABT provisions which apply to handheld and non handheld engines are complex but in broad terms averaging means the exchange of emission credits among engine families within a given engine manufacturerrsquos product line This allows a manufacturer to produce some engines that exceed the standards and offsetting these exceedances with emissions from engines that are below the standard Manufacturers are allowed to exchange credits from handheld to non handheld and vice versa Banking means the retention of emission credits by the engine manufacturer generating the credits for use in a future model year (for averaging or trading) Trading is the exchange of emission credits between engine manufacturers which then can be used for averaging purposes banked for future use or traded to another engine manufacturer
In January 2004 USEPA reported that in 2002 averaging was being used but there was very little use of banking It determined that the initial ABT programs as too complex and included discount rates on credits ABT was simplified in 2004 including the elimination of credit discount and multipliers and limits on credit life To date there has reportedly been limited use of banking however it is anticipated that there will be more widespread use of banking credits if the USEPA proposed Phase 3 comes into effect3 (see below)
Particulate limits (2gkW-hr) also apply to two stroke engines Carbon monoxide and durability limits (or useful life) are also prescribed The durability criteria which were introduced in Phase 2 require that the emission limits must be met through the useful life of the engine The manufacturer determines useful life of each product using standardised product testing procedures and then based on the test results selects the useful life category for each product which can be 125 250 or 500 hours These durability criteria acknowledge the large disparity in usage patterns by equipment type and between commercial and residential users It also takes into account the ability of manufacturers to design and build engines for various design lives and which fit the types of equipment engine is produced for
The March 2000 USEPA report (USEPA 2000) estimated that the expected effects of the Phase 2 regulations would be
bull A 70 reduction in HC+NOx beyond the Phase I standards (which were estimated to have reduced emissions by 32 from the unregulated baseline)
bull A 30 reduction in fuel consumption of small handheld equipment bull Price increases of between $US23 (Class III) and $US56 (Class V) for
handheld equipment

The US EPA is currently considering lsquoPhase 3rsquo regulations which are catalyst based standards to further reduce exhaust HC and NOx emissions from non handheld engines reduce evaporative HC and NOx emissions for both handheld and non handheld engines plus include extended durability criteria These limits are currently at discussion stage only They align with CARB Tier 3 but a longer lead time is proposed

California has particle limits for two strokes useful life criteria and mandatory engine labeling including a consumer advisory hang tag as shown in Figure 1 The USEPA is also considering introducing an air index label
10
Figure 1 Example of a Californian Consumer Advisory Hang Tag The Californian regulations take into account sales weighted emission performance for families of engines An engine family is essentially the same engine being used in different equipment items
In 2003 California adopted a Tier 3 program for exhaust and evaporative emissions and these are based on the use of catalytic convertors The engine classes better align with US EPA categories however the exhaust standards for Class I and Class II are more stringent than the existing US EPA standards

33 Canada
The Canadian small engine market has similarities to the Australia market the majority of small engines are imported from the USA and there is one Canadian manufacturer of small spark ignition engines and one major manufacturer of lawn and garden machines
A Memorandum of Understanding (MOU) which came into effect on 1 January 2000 was signed between Environment Canada and ten manufacturers of handheld equipment and nine manufacturers of engines used in non handheld machines The MOU was intended as an interim measure until regulations could be put in place Under the MOU the manufacturers agreed to voluntarily supply small spark ignition engines designed to meet the applicable USEPA Phase 1 emission standards
In 2003 Canada regulated emission limits for handheld and non-handheld small engines based on USEPA emission limits The regulations apply to model years 2005 and later While there are no separate averaging banking and trading provisions in Canadian regulations Canada allows any USEPA certified engine to be sold in Canada This means that engines that do not meet the standard level but are averaged (or use credits) in the United States can be sold in Canada Manufacturers are required to produce upon request evidence of conformity to the standards and are required to provide written instructions on engine maintenance to the first retailer

34 Europe
In 1998 the European Union introduced exhaust emission limits for small petrol engines through Directive 9768EC and in 2002 introduced amendments through Directive 200288EC The limits in the Directives align with the US regulations however they do not have averaging and banking provisions

The European Union is currently considering including useful life criteria and averaging and banking provisions plus it is considering introducing a Directive to further reduce emissions from diesel engines The objective of the proposal is to tighten emissions standards for engines in general non-road applications in light of technological developments and it taking into account the parallel developments for similar legislation in the United States in order to harmonise the environmental standards and to facilitate trade

4 Australian Market for Small Engines
41 Likely compliance with overseas emissions standards
As part of this assessment an environmental profile of equipment currently on the Australian market has been developed initially based on information from manufacturersrsquo brochures and web sites and industry magazines and then confirmed through follow-up with relevant industry contacts
Each item of equipment has been assessed on its compliance with USEPA CARB or European regulations In most cases it was not possible to match models available on the Australian market with CARB lists (CARB publishes exhaust emissions data on all appliances on its web site) This was mainly due to the inconsistency of model designations and uncertainty about ldquoengine familiesrdquo
Engine characteristics and retail price were difficult to obtain Some brochures also made claims of compliance with USEPA European or CARB requirements The detailed breakdown of current equipment on the Australian market is given in Appendix 1
The majority of small engines sold in Australia are imported and many come from countries that impose emission limits The extent of imports into Australia that do not comply with the country of origin standards is not known Industry estimates that 40 of garden products are sold through importers who are not linked to manufacturers of US EPA or European certified equipment and the source of some products sold here is difficult to establish Victa is the only company producing small engines in Australia Its iconic 2-stroke lawnmower currently cannot meet overseas emission limits
Outdoor Power Equipment Association (OPEA) assisted in identifying the Australian distributors of most brands of powered garden equipment In April 2006 a survey form was sent to a total of 43 distributors representing 97 brands of equipment The survey form sought information about the engine for all petrol-fuelled garden equipment with a power not more than 19kW
Figure 2 Extract from survey form
18
Initial response to the survey was poor Despite follow-up action and efforts from the industry association at the beginning of September 2006 26 distributors had responded to the survey information and only 13 distributors provided all data necessary for benchmarking purposes This resulted in emission compliance data for about half of the estimated products on the Australian market Attempts to match Australian models with the database maintained by the Californian Air Resources Board were also of limited success due to inconsistencies in model designations between Australia and the USA and the manner in which model information is coded in the CARB database

According to OPEA approximately 424000 walk behind lawnmowers and more than 792000 units of outdoor handheld equipment were sold in Australia in 2005-06 In addition there were sales of about 80000 replacement engines and 70000 pumps in 2005-06 most of which were four strokes These figures show that there has been considerable growth in the sales of most products with the exception of chipper shredders and the category lsquohedge trimmers and othersrsquo whose sales declined in 2005shy06 compared with those in 2002 About 17 of walk behind lawnmowers were two stroke and 83 four stroke which is an improvement in the uptake of cleaner engines when compared to 2002 when about 30 were two stroke The situation with handheld equipment is reverse with nearly 79 being two strokes compared to 47 in 2002 However many models of two stroke handheld equipment meet current US emission standards and care should be exercised in using engine type (two stroke or four stroke) as an indicator of emissions performance for this class of equipment
The OPEA 2005-06 sales estimates are shown in Figure 7 OPEA cautions that there is considerable uncertainty about the estimates for brushcutters and blowerblower vacuums as OPEArsquos figures only represent 50 and 60 respectively of sales of these products No estimates of future sales trends were identified during research for this project

Briggs and Stratton (Australia) who import engines from the USA supply the majority of the four stroke engines for handheld equipment sold in Australia and these comply with all the current USA and CARB regulations Imported handheld garden equipment is shipped fully assembled to a branch or distributor and is then sent to a retailer The retailer may or may not provide equipment servicing
OPEA members have expressed concern regarding the increasing sales of imported high polluting two stroke engines that allegedly do not meet any emission standards and come from countries that do not have emission standards One industry representative reported that some of the imported trimmers were being manufactured in China using outdated designs and tooling from two old bankrupt American companies and these are being sold here at about 30 of the price of traditional brands and very low cost generators from China now account for around 70 of total sales It is difficult to confirm this trend without undertaking a detailed examination of Australian import data however the significant increase in the sales of two stroke handheld equipment provides some support for this trend
On the other hand it is claimed by industry that the ride on mower market (predominately with compliant four stroke engines) has been stimulated by the Australian USA free trade agreement

5 Australian Users of Small Engines This section examines the market segments for garden equipment and customer purchasing behaviour
51 General Public
Purchasing behaviour
Research into consumer purchasing behaviour has found that consumers assess a product against a range of attributes for example price weight brand reputation servicing and parts availability warrantees and guarantees experience size promotions and discounts Studies have also revealed that up to 82 of Australians had bought products on the basis of social or environmental factors in the previous year (State Chamber of Commerce 2001) Related to this point the energy star rating ecolabel on whitegoods was viewed as a credible environmental claims system which is well regarded by the general consumer (Product Category Manager Mitre 10 personal communications)
As the purchase of small engine garden equipment by the general consumer is an infrequent purchase which carries a certain of amount of risk With small engines the risk can be functional risk (will not perform as expected) physical risk (for example safe features such automatic cut out on an electric lawn mower) or financial risk especially for the more expensive items The general consumer is likely to lessen the risk by seeking information and by evaluating the information on the available products over a period of time The consumer may also lessen the risk by
bull purchasing well known brands
bull buying the brand offering the best warrantees and guarantees
bull buying the most expensive brand and
bull buying a brand they have used before
Research indicates that the desired attributes of a product may not be well established at the start of a consumerrsquos search process but will often be refined as the consumer learns more about the product The consumer will also use a ranking and weighting process based on desired qualities and trade offs may be made
Reportedly purchases of engine operated garden equipment are based on price yard size fitness for purpose and other features such as weight and ease of starting (Product Category Manager Mitre 10 personal communications) Males are the predominant purchasers of garden equipment however because of changing demographics there has been an increase in the number of women purchasing these products
Less than 5 of lawnmowers purchased are push or electric mowers (Product Category Manager Mitre 10 and industry sources personal communications 2003)
25
Electric mowers are generally perceived as not being as effective as cords have limited range and rechargeable electric mowers require frequent recharging
There is a recent trend towards ride on mowers (all four strokes) probably because of changing demographics specifically older age groups moving to more rural environments with larger yards (OPEA personal communications)
A study (Wilkie 1994) investigated consumer appliance purchasing behaviour and found that the general consumer consulted a range of information sources before purchasing an appliance The appliance salesperson was found to be the most important information source for many consumers Other important information sources include newspaper advertisements friends and relatives catalogues consumer reports and brochureslabels Since Wilkiersquos study the internet will have become increasingly important as a research tool and in some instances as a way to purchase products As part of this study there is evidence of low priced products being sold into the Australian market via the internet only ndash a practice that is likely to increase in the future It was difficult to source any compliance or details on these products
At the retail chain level staff product training is generally voluntary undertaken out of store hours and as an inducement to attend training sessions suppliers usually provide incentives for staff Retail chain purchases are very price driven although some chains are reportedly interested in stocking goods that have credible environmental claims (Mitre 10 and other retail chain sources)
IBIS (2006a) reports that the domestic hardware sector which is dominated by Danks (Home Timber and Hardware Thrifty - Link Hardware and Plants Plus Garden Centre) and Bunnings is classified as a growth market and the sales of lawnmowers and other lawn and garden machinery and equipment represent about 14 of sales revenue
In summary it appears that a range of product attributes influences consumer purchases of lawnmowers and outdoor equipment Currently there is very little information about emissions in any of the information sources a consumer is likely to consult when purchasing these products Nevertheless surveys indicate that consumers are concerned about the environment and are open to including environmental considerations into their purchase decision Educating sales staff about the air emissions from lawnmowers and outdoor equipment together with ecolabels could therefore be important methods for influencing consumers towards the purchase of cleaner products
Equipment Usage
The USA Outdoor Power Equipment Institute CARB (cited in USEPA 1998) and the USEPA (USEPA 1998) have made estimates of annual usage rates and average life spans of outdoor equipment for the general consumer user and for the commercial user Table 13 gives USA usage and lifespan range for selected items of powered equipment

Discussions with members of the Australian industry confirm that Australian hours of use are likely to be similar to the American estimates although this can vary depending on location For example in tropical areas lawns are mowed more often because they grow faster in this climate The American turnover of equipment is however probably higher than here as the Australian consumer tends to keep their equipment longer and so the useful life of a mower is more likely to be on average 10 ndash12 years
52 Garden and Ground Maintenance Services
According to a recent IBIS report (2006b) the revenue for this industry in 2005-06 was $383 million and the industry outlook is lsquobrightrsquo with a predicted annual average 5 growth over the next few years The Australian customer base for garden maintenance services including for lawn mowing is
Households 55 Business 25 Government 20
The sector is reportedly a growth industry due to
bull the aging population
bull the increasing numbers of households that are time poor income rich and
bull the growing trend for professional landscaping which requires a higher level of garden maintenance
27
The main customer base for these businesses includes middle to upper socioeconomic groups the aged and people who are physically disabled Growth is predicted particularly for the franchise industry with demand from the commercialindustrialgovernment sectors (IBIS 2003) A 1999 ABS survey reported that nearly one-third of older people purchased at least one domestic service per fortnight with gardening assistance being the most common This accords with an industry estimate that about 25 of householders pay someone to mow their lawn (Jim Penman Jimrsquos Mowing personal communication) The industry is sensitive to economic conditions and weather for example the drought has slowed growth over the last few years
The garden maintenance sector is dominated by small independent operators with two major franchisers Jimrsquos Mowing and VIP VIP nationally has 600 franchises and Jimrsquos Mowing about 400 Jimrsquos Mowing reportedly mows about 15000 lawns and has 53 of the market (IBIS 2006b) As franchised lawn mowing services represents about 14 of the lawn mowing services nationally it can be estimated that approximately 280000 lawns are mowed nationally by commercial operators
Jimrsquos Mowing and VIP provide training and advice to new franchisees on equipment including proper maintenance schedules Training generally occurs before franchisees purchase their equipment Most franchisees equipment would consist of two mowers a brushcutter an air blower and possibly a hedge trimmer or chain saw Operators prefer four stroke mowers and these are used for an average eight hours per week Brushcutters are generally two strokes as are other motors (IBIS 2006b and Jim Penman personal communication)
From the above it is estimated commercial operators operate mowers for up 34 million hours per year (or 8 of the total estimated mowing hours per year) and purchase approximately 66000 lawnmowers annually (25 of purchases) The sectorrsquos purchases of brushcutters is estimated to be approximately 8000 units per year or 37 of purchases Table 13 provides US commercial userrsquos annual average hours of use and average equipment life spans ndash it would be anticipated Australian rates would be similar
The main businesses contracting to provide ground maintenance services to the corporate and government sector (including universities) are Spotlessrsquos Open Space Management Transfield and Programmed Maintenance Services all of which are diversified publicly listed companies plus the Danish owned company ISS (previously Tempo Services) (IBIS 2003 and 2006b and company websites) The type of services they provide means it is likely they would have an array of equipment and a preference for the more powerful ride-on mowers and for Class V handheld equipment
53 Government Purchasing
The way purchasing decisions are made by government or other large organizations is generally very different to the approach taken by the general household consumer
bull many of the purchases are for large quantities of goods
28
bull there are well established policies and procedures in place to guide purchasing with the purchase criteria established early in the buying process and
bull those making the purchase are likely to be more knowledgeable about the product than the average consumer and they are usually not the eventual user of the goods
Value for money fitness for purpose ability to supply and over recent years environmental aspects are likely to be important factors in the purchasing decision for Government
Local State and Commonwealth Governments have responsibility for the upkeep of public assets many of which include public open space and other outdoors areas At the State and Federal level these include schools universities sporting facilities hospitals and defence facilities These services may be outsourced individual departments may undertake maintenance and purchase their own equipment or they may purchase equipment through a central purchasing facility With the central purchasing facility these items are generally purchased under contract While there is an increase in the inclusion of environmental considerations in the selection criteria for purchasing goods and services especially under contract these considerations mainly relate to waste management and recycling criteria and not air emissions
Local councils in some states for example NSW generally take responsibility for ground maintenance within their council areas or for some smaller councils the service may be contracted to a neighbouring council In other states such as Victoria there is a trend to outsource ground maintenance contracts to commercial providers
It is unknown what proportion of total sales that direct Government purchases represent however it likely to represent a relatively small share of several percent of the overall market
In summary
bull The general household consumer represents the major market segment for garden equipment accounting for up to 90 of product sales
bull Government is likely to be relatively small direct purchaser of garden equipment
bull Commercial garden services to households purchase approximately 25 of lawnmowers per year and 37 of brushcutters
bull Large ground maintenance companies are likely to prefer larger and more powerful equipment such as ride-on mowers

6 Result of Stakeholder Consultation
61 Regulations
The Small Engine Expert Panel ndash Outdoor Equipment considered in depth an approach to take to improve the emissions performance of outdoor garden equipment sold in Australia Discussions were particularly focused on the growing influence of cheap high emissions imported products together with the difficulties that the local manufacturer of lawn mowers is likely to face in complying with the relevant overseas standards As part of this process the industry representatives on the Panel held additional discussions and they consulted international industry experts at the manufacturing level in Europe the USA and Japan
OPEArsquos preference is for the adoption of regulations based on the USEPA standards with Phase 1 being adopted possibly from as early as 2007-08 The industry then proposes that Phase 2 be introduced in 2012 Phase 1 USA EPA standards were adopted in the USA in 1995 to be applied to equipment manufactured from 1997 and Phase 2 standards were introduced in 2002 through to 2007 and these included averaging banking and trading provisions A comparison between the USA Phase 1 and Phase2 standards is given in Table 14 The USEPA is discussing Phase 3 limits for the adoption in 20102011 which includes tighter exhaust emission limits for non-handheld equipment
The emissions limit of the two stroke lawn mower manufactured by the sole Australian manufacturer are well above USA Phase 1 limit for non-handheld equipment One avenue to address this issue which was supported by the Expert Panel ndash Outdoor Equipment would be to place lawn mowers in the US EPA Category 5 (engines gt50cc) This would result in emissions for two stroke lawnmowers being limited to 161 gkW-hour HC + NOx compared to the USA regulated limit of 161 gkW-hour HC + NOx Doing this would align the ramp-up timetable for mowers with that of other garden products
Table 14 Comparison between the USA Phase 1 and Phase 2 standards
Emission Limits GkW-hr
Phase 1 (1997 ndash2001) Phase 2 (2007) HC NOx HC+NOx CO HC+NOx CO

Phase 2 limits were phased in between 2002 -2007 during which time they became tighter for simplicity only the 2007 are shown in this table (see Table 2 for more details)
30
In addition to limiting emissions the Expert Panel support the inclusion of the durability criteria which apply in the USA under Phase 2 standards and certification documentation from either the USA or Europe as adequate proof of conformity Equipment that has not been tested and certified to USA or European standards will be required to have the engines tested in a NATA certified laboratory
Some in the industry argued that regulations should include provisions for averaging for companies that wish to use it however they felt banking and trading provisions would not be necessary Industry representatives were not supportive of any Australian consumer labeling requirement instead OPEA members are willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models
62 Discussion on recommended regulations
Timing of introduction
Some industry representatives argue that introduction of Phase 1 standards in 2007-08 will not give the industry an adequate transition period in which to develop competence in emissions certification establish new procedures and tooling in the dealers workshops train dealers and technicians on legal requirements distribute specific tooling and spare parts and reduce stocks of old (non certified) products without incurring an undue financial burden While others in the industry prefer progressing straight to phase 2 standards
If the OPEA preference for the adoption of the United States Phase 1 regulations which operated in the USA between 1995 and 2001 were introduced in Australia in 2007-08 they would be well behind the USA standards and worldrsquos best practice Furthermore the introduction of the United States Phase 2 - 2007 limits in Australia in 2012 would if the USEPA introduce Phase 3 in 2010-11 see emission limits for lawnmowers and other non handheld garden equipment in Australia still lagging United States standards and worldrsquos best practice
To introduce regulations in 2007-08 will require Government firstly to determine the most appropriate mechanism under which to enact the regulations draft the regulations prepare the regulatory impact assessment consult with the broader community and then finalise the regulations It is likely an Act of Parliament will be required at the Commonwealth level followed by complementary legislation at the State and Territory level It is possible for this to be achieved in less than a two year timeframe (as was the case for the Water Efficiency Labelling Scheme) However regulations that do not have a level of perceived urgency would take longer The level of importance and urgency to control emissions from small engines has yet to be debated and determined
31
Modified USEPA limits for lawnmowers
From the 183 lawn mowers identified through the market survey Victa is the main (possibly sole) provider of two stroke mowers with the other lawnmowers having cleaner four stroke engines
Victa is undertaking work to produce a cleaner product Victa estimates it would need a number of years to complete development production tooling and commercialisation of the cleaner engines In January 2007 it released a new two stroke carburettor lawnmower that has reduced engine emissions by more 30 but the combined HC and NOx emissions are still above USEPA Phase 1 limits Victa says this new engine is the outcome of four years of collaborative work by Victa and the University of Technology Sydney Victa is continuing with this research to further reduce emissions
A clause that allows exemptions to be granted as occurs in other countries could be included in the regulations however Victa argues that this would create uncertain trading conditions for the company for a period of time until an exemption were granted
Placing lawn mowers in the US EPA Category 5 (engines gt50cc) has the risk of opening the Australian market to more two stroke lawn mowers which has the greatest use of any outdoor powered equipment however it should see the continuance of the sole engine being manufactured in Australia In 1995 when it was introducing small engine emission limits the USEPA faced a similar issue with two stroke lawn mowers and used a similar approach by allowing two stroke lawn mowers to comply with the handheld standards It also specified that the number of two stroke lawnmower engines allowed to meet handheld standards would be subject to a declining annual production cap with the allowance provided by the production cap being phased out in 2003 There is also similar precedent for small engine emission limits that depend on engine type - European regulations for marine outboard motors set less stringent requirements for two stroke motors
Averaging Banking and Trading Provisions
The US EPA did not have averaging banking and trading provisions in Phase 1 and therefore all small outdoor engines were required to meet the Phase 1 limits It only introduced ABT provisions in the much more stringent Phase 2 as they would allow the most economic introduction of cleaner engines The industry claims the systems to use this provision are available and can be implemented in Australia by those who wish to use it at little cost to government
Industry claim that any supportive economic data related to averaging is sensitive and confidential It is there difficult without substantial justification by the industry to support the provision for averaging in conjunction with Phase 1 particularly given the elapsed time between the introduction of Phase 1 in the USA and their recommended introduction in Australia If there are some low volume equipment items that still cannot meet the USAEPA Phase 1 standards then these could be subjected to
32
exemptions if adequate justification can be provided (exemptions for small volumes were available under the USEPA regulations)
It was noted that for government to implement regulations a regulatory impact statement is required and this requires an assessment of the costs and benefits of the options considered with clear overall benefits shown for the preferred option Therefore if the option for manufacturers to use averaging were to be considered more information to support its inclusion would be required
Other options that could be considered to circumvent the inclusion of averaging include
i including clauses that give manufacturers the ability to apply for exemptions from the regulations for classes of equipment that have small sales volumes (these provisions are available in the USA)
ii limiting the regulation to popular types of equipment
iii using the end-of-model life provisions that have been used in the Australian Design Rules for cars In effect the end of model life provisions require new designs to comply from the implementation date but allow older models to remain on sale for a few more years This is an alternative to ABT because it facilitates earlier introduction of the regulation
iv Having a phase in period of say 2 years during which existing models can continue to be sold but new models coming on to the market must comply with the new standards At the end of the phase-in period all models must comply with the new standards This is an approach that is used when Australian Design Rules (ADRs) are introduced for motor vehicles
Consumer Information
Current Australian directions to reduce the environmental impact of consumer products favor tiered benchmarks using a lsquostarrsquo rating system (see Appendix 3 for examples such as the Mandatory Energy Efficiency Label and the Water Efficiency Labelling Scheme)
As products generally arrive in Australia assembled and packaged industry considers a mandatory requirement to label products with an Australian style star rating would impose a cost on distributors that would drive up the retail price of products Instead the OPEA members were willing to supply emissions data for inclusion in a web-based database that would allow purchasers to assess the environmental credentials of different makes and models Given the diverse nature of the industry it is unlikely a database would provide complete coverage of all products on the Australian market but inclusion in the database would indicate that the manufacturer has a commitment to environmental performance It was acknowledged in discussions that at least some Phase 2 compliant products would become available prior to 2012 and the web-based database would provide one method to promote those cleaner engines
33
In summary the Recommendations of the Expert Panel
1 Mandatory air pollutant emission standards to be introduced in Australia for all outdoor equipment (lt19kW) powered by spark-ignition engines The development of any regulation would need to be based on a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment which should be commenced immediately
2 Proposed standards to mirror US EPA regulations (compliance with equivalent EU regulations also acceptable)
3 Timing (subject to completion of assessment of costs and benefits)
(a) US EPA Phase 1 ndash Effective from 2007 2008
(b) US EPA Phase 2 ndash Fully implemented in 2012 (in step with 2007 USEPA limits) with phase-in period andor ABT over 2008-2012 to provide for early introduction of cleaner product
4 Walk-behind 2 stroke mowers to be included in US EPA Category 5 (gt50cc) product classifications Implementation timing to be as in Recommendation 3 above
5 All products also to be certified to relevant EPA durability categories
6 Subject to further review ABT (if included) may be phased out after 2012
34
7 The Way Forward
The optimum approach for garden equipment out engine emissions of options needs to be sustainable and cost effective This will need to be determined through a costs and benefits analysis (CBA) CBA assigns monetary values and typically assesses the impacts on the consumer on human health on the environment on industry and on government A detailed costs and benefits analysis is beyond the scope of this report however the following sections draws on available information to provide some indication of the possible costs and benefits that are associated with emissions from garden equipment engines
Air Quality Benefits
Environment Canada estimated the introduction of the regulations would result in a 44 percent reduction in combined HC+NOx emissions from small engines used in garden equipment and reduction in individual air pollutants over a 25 year period as shown in Table 15 The Canadian estimates incorporate the benefits that would accrue from the MOU signed with the industry in 2000 plus the benefits from the regulations introduced in 2003 In 2000 Canada imported around 13 million small spark-ignition engines and machines (ie a similar number to Australia) with 80 supplied by the USA

Other Environmental Costs and Benefits
In addition to the human health benefits associated with reduced exposure to ozone there is a range of other public benefits including reduced damage to vegetation and therefore higher crop yields less damage to materials and structures particularly
35
some rubber products and improved visibility due to a reduction in smog haze Plus there are benefits associated with lower emissions of other air pollutants
To date there appears to have been little work undertaken in assigning a monetary value to these benefits as it is considered that they are likely to be small compared to human health impacts
Health Costs and Benefits
The Final Impact Assessment for the Ambient Air Quality National Environment Protection Measure (NEPC 1998) estimated that the health damage costs from exposure to ozone nationally to be in the range of $90 ndash $270 million (in 1998 dollars) This figure did not include mortality costs because of difficulty in assigning a figure to human life nor did it include costs associated with minor symptoms such as sore throat cough headache chest discomfort and eye irritation that can result from ozone exposure On the cost of ozone exposure the Impact Assessment states that lsquothe social well-being associated with potentially 6 and 20 million fewer irritating symptoms annually cannot be reliably quantified but at $1 a symptom it adds up to an appreciable amountrsquo
Since the Air NEPM Impact Assessment ozone levels in Australian urban areas have not fallen significantly but the population and medical costs have increased since then However using the above figures to make a rough estimate the contribution made by engines used in lawnmowers (ie not including other garden equipment) to the health damages cost from ozone exposure would be at a minimum $36 - $108 million not including the cost of mortality or minor symptoms As any action on these engines is likely to only remove high emission engines over a decade or more a CBA would be required to include an assessment of the proportional health benefits that would accrue from only removing the high emitters over time
Costs and Benefits to the Consumer
In 1995 the USEPA estimated that on average the cost to the engine manufacturer to install the necessary emission control technology to meet Phase 1 standards (which didnrsquot have ABT) would be approximately $US2 per engine used in nonhandheld equipment and $US350 per engine used in handheld equipment It also estimated that this would translate to sales-weighted average price increases of about $US7
The introduction of phase 2 regulations USEPA estimated would result in price increases of between $US20 and $US64 for handheld equipment depending on the equipment class (USEPA 2000) where handheld engines ranges in price from $60 to $1000 (USEPA 1995)
In addition to emission reductions the implementation of exhaust emission limits has the advantage of reducing fuel consumption and lowering operating costs to the consumer For example the USEPA estimated that for Phase 1 limits that applied between 1995 and 2001 on an average sales-weighted engine basis would decrease fuel consumption by 26 percent for non handheld equipment and a 13 percent decrease in fuel consumption for handheld equipment (USEPA 1995) Phase 2
36
(current limits) would result in a further decrease in fuel consumption of approximately 30 percent for handheld engines
When the USEPA considered the fuel savings offset and the retail price increase it estimated that the average sales-weighted lifetime increase in cost would be about $US650 per handheld engine while nonhandheld engines will realize a lifetime savings of about $US250 per engine This does not include the lifetime savings in maintenance costs which should further benefit the consumer (USEPA 1995)
Euromot (The European Association of Internal Combustion Manufacturers) claims that compliance with European minimum performance standards that do not have ABT provisions adds around 30 to the cost of some products that have had to be brought into compliance4 compared to products sold under the ABT system in the US
Costs and Benefits to Industry and Government
As there is only one local manufacturer among the 43 distributors of powered outdoor garden equipment sold in Australia and all others are importers the main costs to reduce the emissions contribution made by these engines will be associated with program administration and compliance particularly if regulations are introduced
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of measures to improve the energy efficiency in household appliances As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs (ie regulated tiered benchmarks) and minimum mandatory energy efficiency requirements (ie a regulated simple benchmark) While the household appliance market is considerably larger than the garden equipment market the Commissionrsquos final report contains some information that is useful for determining the approach that could be used to establish an emissions reduction scheme for garden equipment A summary of relevant sections of this report is provided in Appendix 3
The Commission identified both administration and compliance costs associated with labelling programs and minimum mandatory energy efficiency requirements as well the impacts these had on product suppliers
The Department of the Environment and Water Resources provided details to the Commission on the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs The information provided showed that
bull the administration costs of the simple benchmark approach were substantially lower (less than one tenth) than for labelling and 84 per cent of administration costs were passed on to appliance purchasers with the remainder borne by governments
4 Presentation by Dr Holger Lochmann Rob Baker Axel Rauch Stihl 19 April 2006
37
bull the compliance costs for labelling are higher
bull minimum mandatory energy efficiency requirements can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between introduction and the implementation of the regulations
bull The increased cost to appliance purchasers of labelled appliances was about two and half times higher compared to appliances purchased under minimum mandatory energy efficiency requirements this being due to consumers voluntarily purchasing more efficient appliances
Overall the Commission considered that labels should be more actively considered as an alternative to minimum performance standards The Commissionrsquos support was based on the ability of labels to amongst other things
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood so they can help the consumer make better-informed choices
bull Have net social benefits and possibly have net benefits for consumers
bull provide a greater incentive for suppliers to sell environmentally better products
bull warn consumers through a disendorsement label that an appliance is very inefficient This approach can discourage but not prevent consumers from buying the poor performing product
71 Options to Reduce Emissions from Garden Equipment Engines
There is a range of options that could be considered for reducing emissions from engines used in outdoor garden equipment in Australia These include
1 Do nothing
2 Partnership Programs
3 Quasi regulation
4 Co-regulation
5 Regulations
In the following discussion about these options many Australian examples are mentioned Further details about these programs plus an overview are provided in Appendix 2
38
72 Option 1 ndash Do Nothing
Based on data supplied by OPEA the sales of high emitting two stroke carburettor engines as a percentage of engines used in outdoor equipment increased during the period 2002 to 2005-6 (see Table 12) from 463 to 593 and overall sales number increased by 38 during that period There is no indication that in the short to medium term that sales of equipment with two stroke carburetor engines will decrease in overall sales numbers or as a percentage of sales Therefore under the lsquodo nothingrsquo option emissions from outdoor garden equipment will continue at the same rate or perhaps based on sales figures of two stroke carburetor powered equipment at an even higher rate in the future
73 Option 2 ndash Industry - Government Partnership
In the discussion papers prepared for the NSW small engine project (2004) some examples of successful voluntary Government-Industry Partnership programs were provided The examples included were
bull the National Industry Reduction Agreement where the major newspaper and magazine publishers in Australia agreed to promote recovery and recycling of old newspapers and magazines
bull the NSW EPA-Oil Industry MOU on Summer Fuel the National Packaging Covenant (which has legislative backup) and
bull the EPA Victoriarsquos agreement with the Altona Chemical Complex
From the Australian programs reviewed it appears that the best indicators for successful partnership programs are
bull a relatively small number of firms within the industry
bull a commitment and involvement by all of the industry
bull clear program aims and objectives plus program targets and
bull a willingness by the industry to enter into a cooperative partnership with government
There are 43 identified distributors selling 97 brands of outdoor powered equipment in Australia Many of the major distributors are members of OPEA but there are many distributors who are not members It is therefore unlikely that the even the majority let alone all of the Australian distributors would commit to a industry-government partnership to reduce emissions
74 Option 3 - Quasi Regulation
Quasi regulations can take a range of forms the most usual being the establishment of a code of practice that industry endorses and implements A fundamental part of the code of practice would be emissions standards There are few examples of the use of codes of practice to limit emissions
39
Governmentrsquos role under this scenario is likely to be in assisting in the development of standards
The likelihood of this option being successful for similar reasons to the industry government partnership option is low
75 Option 4 -Co Regulation
Co-regulation is an agreement by industry and government to certain undertakings that support the uptake of cleaner products with a regulatory base It allows industry program flexibility to achieve certain negotiated targets Australian examples of coshyregulation include
bull The Green Vehicle Guide which operates through an industry government agreement where industry report test results to government in an agreed format within a certain timeframe Government manages the data and promotes the program This program is underpinned by Australian Design Rules for motor vehicles
bull The electrical appliance stand-by power program where there are agreed targets established that industry is required lsquovoluntarilyrsquo to meet failure to achieve the targets will result in regulation
bull The Packaging Covenant which is a program that allows industry the flexibility to design it own programs to reduce packaging waste and achieve certain target The Covenant is complemented by the NEPM on used packaging which specifies certain government responsibilities to support the program plus measures that will be introduced if targets are not met
Given the large number of distributors on the Australia market co-regulation for engines used in garden equipment using a similar form to the standndashby power program or the packaging program - an agreement by industry and government on a percentage reduction target for the sale of high emitting engines within a specified timeframe together with an agreement that regulation will be adopted if the target is not met ndash is also unlikely to be successful
76 Option 5 - Regulation
Regulation which requires a clear acknowledgement of a sufficient problem by Government places uniform mandatory compliance obligations on industry The costs associated with regulations are usually shared between government and industry with the development of regulations and program administration costs being borne by government with industry meeting compliance costs including emissions testing and if applicable labelling costs
It could argued that regulation should be introduced in the States or Territories where there are exceedances of the Air NEPM ozone standards However development of state based regulations for garden equipment engines emissions is unlikely as they would be incompatible with the 1992 Intergovernmental Agreement on the
40
Environment signed by the Commonwealth States and Territories and existing Commonwealth and State Government mutual recognition legislation The Intergovernmental Agreement on the Environment which underpins the development of National Environment Protection Measures obligates all jurisdictions to ensure equivalent protection from air pollution to all Australians
In addition enforcement of any state based legislation would be a key problem Under the Commonwealth Mutual Recognition Act 1992 and the Trans-Tasman Mutual Recognition Act 1997 goods that are imported into or produced in an Australian State or Territory or New Zealand that can be sold lawfully in that jurisdiction can be sold freely in a second jurisdiction even if the goods do not comply with the regulatory standards of the second jurisdiction This means non-regulated small engine products legally sold in one State could be legally sold in any other state regardless of whether emissions limits on small engines applied in that State
National regulation on the other hand would provide national consistency It would also provide the opportunity to adopt worldrsquos best practice standards and incorporate penalties for non-complying parties
Under the Australian Constitution the Commonwealth does not possess specific legislative powers in relation to the environment and heritage There are however a number of legislative powers that can support environment and heritage legislation Furthermore Commonwealth legislative powers can be used cumulatively For example the Commonwealth Parliament can make laws under section 51(20) of the Constitution with respect to ldquoforeign corporations and trading or financial corporations formed within the limits of the Commonwealthrdquo
Legislative mechanisms may also be created through the development of a National Environment Protection Measure (NEPM) that then becomes law within each jurisdiction A NEPM can accommodate flexibility of implementation where jurisdictions that have elevated ozone levels can tailor their NEPM program to their specific air quality needs An example of this flexible approach is the Diesel NEPM which has a suite of programs which can be implemented by jurisdictions
From the review of Australian regulations to reduce the environmental impacts of products and the overseas approaches to control emissions from small engines two regulatory approaches become apparent a simple benchmark or tiered benchmarks These are outlined below
Regulatory Option1 - A Simple Benchmark Approach
The most basic regulatory approach that could be taken would be to have a single emission standard (or as per the USA Europe and California a number of emission standards based on power and application) for combined HC + NOx emissions All equipment with new engines sold in Australia from the date the regulations are introduced This approach would
bull remove the all high emission engines from sale
41
bull be supported by an Australian Standard and
bull provide consumers with confidence that all products meet certain emissions standard
Regulatory Option 2 -Tiered Benchmarks
Current Australian directions to reduce the environmental impact of consumer products favour tiered benchmarks using a lsquostarrsquo rating system (see Appendix 2 for examples)
For engines used in garden equipment a tiered emissions labelling system could be based on the USEPA Phase 1 and Phase 2 standards use a system of lsquostarsrsquo to provide information to consumers about environmental performance but not limit consumer choice A tiered lsquostarrsquo system approach would
bull reward those products with more stars that meet the more stringent overseas standards
bull either operate with minimum emissions performance standards or disendorsement labels
bull be supported by a product label and possibly a web database
bull provide consumers emissions information and the option to purchase a lower emission engine
bull be supported by an Australian Standard and
bull be devised to meet worldrsquos best practice which is an overarching approach supported by Government
Table 16 summarises the main strengths and weaknesses of the above options
42
Table 16 Main Strengths and Weaknesses of Each Option
Strengths Weaknesses
Do Nothing Does not limit consumer choice Emissions contribution likely to grow No cost to government No barrier to new market entrants selling
high emitters Consumers have a wide choice of products Industry unchecked amp product dumping
likely No enforcement recourse on environmental grounds available
Partnerships Some sharing of responsibility government Slow if any reduction in high emitters
ndash industry
Potential for Government assist in Few if any companies likely to join and no advancing reductions in high emitters restrictions on non signatories Reduction targets set Below worldrsquos best practice
Quasi Regulation Similar strengths to partnership option Similar weaknesses to partnership option as
few if any companies likely to adopt code of practice
Co-Regulation Ongoing consultation between industry and Due to industry diversity targets unlikely to government recourse to regulation be met Targets set and can require new market Slow reduction in emissions entrants to achieve targets Can have implementation flexibility Emissions test standard adopted
Regulation Option 1- Simple Benchmark Worldrsquos best practice standards can be ovide incentives to manufacturers to promote low adapted and is mandatory emitters
Recourse to legal action available for non Does not provide consumers with emissions compliance information Significant quantifiable health benefits Cost of enforcement borne by taxpayers Requires compliance by all industry and High cost to government bans high emitters
Regulation Option 2 ndash Tiered Benchmarks Provides consumers with emissions information but does not limit choice Incentives for manufacturers to sell low emitters Potentially significant quantifiable health benefits Can be designed to overcome ABT issue
Significant administration and compliance costs to Government High cost to government and industry and will increase retail price of engines Does not ban high emitters
43
77 Preferred Approach
From the above discussion and from the review of garden equipment on available to the Australian consumer there are many companies selling powered garden equipment on the Australian market and the market is very competitive Furthermore from the Expert Panel discussions and stakeholder consultation it is apparent that it is highly unlikely that all the companies in the garden equipment industry would engage in or commit to a voluntary program to reduce their productsrsquo exhaust emissions It is therefore clear that the only feasible path to reduce emissions from these small engines is through regulation
While regulations of emissions from small engines used in garden equipment in Australia are likely to be based on overseas regulations they need to strike a balance between improved environmental outcome harmonisation with international standards and the characteristics of the local industry With regulation optimum emissions reductions are achievable especially by combining minimum emissions standards with tiered product labelling Whether this approach is justifiable on economic grounds that is the benefits outweigh the costs can only be determined through a detailed impact assessment Based on these findings it is recommended that a formal assessment of the costs and benefits of nationally regulating 2 and 4 stroke lawn mowers and handheld power equipment should now be commenced

Appendix 2 Examples of Current Australian Benchmarking Programs
The following describes in varying degrees of detail a number of current Australian benchmarking schemes classified by program type simple bench mark approaches tiered benchmarks and government industry partnerships This appendix concludes with a summary table of these programs with an assessment of their effectiveness
1 Introduction
Simple benchmark schemes (described below) such as the woodheater standards set a single point hurdle rate whereas the green vehicle guide use tiered benchmarks The new water efficiency labelling scheme and minimum energy efficiency performance standards uses both a simple benchmark through minimum performance requirement plus tiered benchmarks incorporated into labels as lsquostarsrsquo Other approaches such as the stand-by power program and the Victorian Altona Complex VOC reduction target set goals for achievement within a specified time period Other approaches taken to reduce environmental impacts include the National Packaging Covenant which uses a program based on individual companies developing tailored approaches to suit their circumstances and is supported by enforcement capability through the National Environment Protection (Used Packaging Materials) Measure (the NEPM)
2 Simple Benchmarks
21 Minimum Energy Performance Standards (MEPS)
Purpose
MEPS prescribe a minimum allowed energy performance for specific appliances Appliances that are less efficient than the relevant standard are excluded from the market
Background and Strategy
In October 1999 as part of the National Greenhouse Strategy (1998) nationally consistent MEPS and labelling schemes were adopted across Australia
Independent NATA accredited laboratories undertake product compliance checks to see whether products perform in compliance with MEPS requirements For example
bull In 2003 the government conducted check tests on eight appliance models all of which were found not to meet the claims made on the energy performance labels Two products were deregistered one was found to have not been registered and action was pending on the remaining five products (AGO 2003b)
55
bull Other regulatory actions undertaken in 2003 included fines of $3000 and $8000 against two Western Australian retailers who were found to have sold appliances without energy performance labels Queensland and Victorian retailers received infringement notices and fines totalling $10 000 (AGO 2003b)
Summary RegulNated minimum performance standards based on an Australian Standard
22 Energy Star
Purpose
An endorsement label that indicates an electronic product has achieved a specified standard when it is not performing its core function (ie on stand by)
Background and Strategy
Energy Star is a voluntary endorsement labelling program developed by the US Environmental Protection Agency (US EPA) It has been operating in the USA since 1992 and has been adopted by a number of countries including Australia Energy Star sets voluntary standards for reducing the electricity consumption of electronic equipment when it is not performing its core function
The Government stand ndash by program which is outlined below complements the energy star labelling program
Summary Voluntary endorsement label
23 Woodheater Standards
Purpose
To reduce particle emissions through Australian Standard compliant woodheaters
Background and Strategy
Since 1992 Australian StandardNew Zealand Standards have been introduced to improve the performance of wood heaters
The first standard for wood heater emissions AS4013 (1992) was published in 1992 and was revised and published as a joint AustralianNew Zealand Standard in 1999 ASNZS4013 (1999) Domestic solid fuel burning appliances - Method for determination of flue gas emission This Standard provides a test method to measure particles emitted by residential solid-fuel burning heating appliances
56
The 1992 Standard included an upper limit for acceptable particle emissions of 55 grams of particles per kilogram (oven-dry weight) of fuel burnt This emission factor was reduced to 4 gkg in the 1999 revision of the Standard The Standard applies to solid-fuel burning space-heating appliances (including those fitted with water heating devices) with a heat output of 25KW or less It does not apply to masonry fireplaces cooking stoves central heating appliances or water-heating-only appliances
AS 4013 (1999) is complemented by ASNZS4014 (1999) Domestic solid fuel burning appliances - Test Fuels and ASNZS4012 (1999) Domestic solid fuel burning appliances - Method for determination of power output and efficiency
The woodheater industry was instrumental in initiating the development of standards and it lobbied states and territories to enact legislation to mandating that woodheaters be required to meet the standards As the health affects of particle pollution have become more apparent and as some jurisdictions are having difficulty in meeting national particle standards Government has become more proactive in controlling woodheaters and more supportive of tighter standards
All states and territories with the exception of South Australia have regulations that restrict emissions from new woodheaters although Victoria for example only introduced its regulations in 2004 compared to Tasmania who introduced regulations in 1993 These regulations require that new woodheaters comply with the Australian Standard ASNZS 4013 The State regulations however are not uniform
Many woodheaters that are currently certified for sale do not comply with the revised standard as verified in a National Woodheater Audit Program undertaken in 2004 Seven of the 12 wood heaters tested failed to meet the ASNZS 4013 particle emission limit In addition 55 of heaters were found to have deviations from the original designs and 72 had labelling faults that could adversely affect emissions performance
Testing and certification are administered by the industry association
Summary State and regulations requiring compliance with Australian Standards Certification administered by industry association
24 Standby Power
Purpose
To reduce lsquoexcessiversquo energy consumed in electrical appliance standby mode sold in Australia through in the first instance voluntary targets Appliances covered by the program range from information technology equipment such as PCs and photocopiers entertainment equipment such as TVs DVDs and sound systems major appliances such as water heaters dishwashers and refrigerators and small appliances such as smoke detectors and bread makers
57
Background and Strategy
In 2000 standby power was estimated to constitute 116 per cent of Australiarsquos residential energy use costing households over $500 million and leading to the emission of over 5 million tonnes of carbon dioxide equivalent (AGO 2002c) Holt and Harrington (2004) estimated that standby power consumption in Australia could be reduced by 56 per cent by 2020 (Productivity Commission 2005)
In August 2000 all Australian jurisdictions agreed to pursue efficiencies in standby power consumption of energy-consuming products through support for the International Energy Agencys One -Watt program and endorse its incorporation into theprogram of work
Australia reportedly has taken the lead on implementing the One- Watt program even though many of the products sold in Australia are imported
During 2002 government agencies consulted with stakeholders about ideas to reduce standby The standby strategy which proposed a list of targeted potential product types was presented to the Ministerial Council on Energy
In September 2003 an interim test method for the measurement of standby power ASNZS 62301-2003 (int) based on an internationally recognised standard was published Also during this period work commenced on developing draft product profiles for high priority targeted products
Once product profiles are completed interim voluntary date-specific targets are made The product sales are then monitored to determine progress towards the interim target If it is then determined that inadequate progress is being achieved by a significant number of suppliers then government will regulate
For example the interim 2007 target for clothes washers is as follows
Product Off mode power End of program mode
lt 1W lt 4 W
The National Standby Strategy Target to be achieved by 2012 for clothes washers is as follows
Off mode power End of program mode lt 03 W lt 1 W
In support of the clothes washer program Government will
bull consider creating a Government Purchasing Policy to buy low standby clothes washers where available and fit for purpose
bull collect data on all modes for new clothes washers and analyse trends
bull highlight the range of performances by publishing performance data on clothes washers on a website or by other means
58
bull progressively include standby energy consumption into the Comparative Energy Consumption for labelled products such as clothes washers and clothes dryers
bull work with the Standards Committees to finalise the details of modes and test methods for the relevant standards
bull determine in 2008 if progress is inadequate and if regulation is required
Summary Industry targets possible future regulation
3 Tiered Benchmarks
31 Mandatory Energy Efficiency Label ndash the Energy Star Programs
Purpose
To enable consumers to easily compare the energy performance of electrical appliances used by households and firms through a labelling scheme
Background and Strategy
Several Australian states commenced mandatory energy efficiency labelling for major appliances in the mid-1980s In 1992 it became mandatory across Australia for initially refrigerators and later freezers clothes washers clothes dryers dishwashers and air-conditioners (single phase only) to carry the label when they are offered for sale This labelling program is regarded as one of the most successful in the world (Wilkenfeld and Assoc 2003) It is administered through the Australian Greenhouse Office
The energy rating label for dishwashers
(ldquoa joint government and industry programrdquo) and a website address (wwwenergyratinggovau) and has two main features
bull the star rating which gives a quick comparative assessment of the models energy efficiency and
bull the comparative energy consumption (usually kilowatt hoursyear) which provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria Appliances must meet these criteria before they can be granted an Energy Rating Label
The Energy Rating Label includes an endorsement

Since its introduction the star rating label seems to have established a high level of recognition with consumers Consumer research (Artcraft 2003) indicates that the different information on the label appeals to different consumer segments interested in purchasing an appliance
When a manufacturer gains approval to use the label they pay for and produce the label in accordance with specifications on size colours fonts layout and design A similar colour scheme and design to the energy consumption label is also used for the compulsory fuel consumption label on new passenger and light commercial vehicles
The labelling scheme is underpinned by regulation whereby regulated Minimum Energy Performance Standards (MEPS) provide the environmental benchmarks that the appliances are required to meet Appliances that do not meet the minimum energy performance standards can be withdrawn from the Australian market
When the energy rating program was reviewed in 2000 technology had advanced to the point where a large percentage of appliances had achieved the maximum number of stars so the rating system was tightened It is estimated that over the 25 year period 1980 to 2005 there will have been an overall reduction in energy consumption of around 70 by the most popular sized refrigerators (with freezers) (Harrington L and Holt S 2002)
In addition to the energy consumption label there is a website (wwwenergyratinggovau) with a comprehensive database of all appliances their star rating and energy consumption In 2002 there were around 220000 hits on the programrsquos various websites and 523000 in 2003 reportedly representing 80000 visits by individual inquirers The website hit rate is estimated to represent almost 10 of consumers who are considering purchasing an appliance (Holt et al 2003)

When the energy rating program was reviewed in 2000 technology had advanced to the point where the Scheme had to be tightened because a large percentage of appliances had achieved the maximum number of stars For example energy use by refrigerators was around 70 compared to that used when the scheme started (Harrington L and Holt S 2002)
60
Regulations
State and Territory legislation refer to the relevant Australian Standards This approach simplifies the State and Territory legislation and makes it relatively straightforward to maintain national consistency of appliance and equipment energy efficiency standards even when standards are continually being revised
The testing procedures and technical requirements for the label and also Minimum Energy Performance Standards (MEPS see below) are incorporated into the applicable Australian Standards Products for sale must be registered with one of the State regulators
Program Administration
The labelling program and MEPS program are administered by the National Appliance and Equipment Energy Efficiency Committee (NAEEEC) which is ultimately directed by the Ministerial Council on Energy
Requirements for Appliance Suppliers
Appliance suppliers are required to
bull Submit applications for product registration and these must include a test report or other data to demonstrate that the appliance meets the relevant Australian Standard
bull While test reports on three separate units are required for most products there is no particular requirement for test laboratories to be accredited or products certified for registration for energy labelling and MEPS in Australia Test reports from the manufacturers laboratory are satisfactory However if there is evidence that results from a particular laboratory are unsatisfactory regulators can mandate test reports from an accredited laboratory
Summary Mandatory labelling scheme backed by regulations and an Australian Standard
32 Water Appliances Water Efficiency Labelling and Standards (WELS) Scheme
Purpose
A labelling scheme backed by legislation to promote domestic water efficient appliances
Background and Strategy
A voluntary water efficiency industry administered labelling scheme has been in existence since 1988 The water efficiency ratings and details on the label design are covered in ASNZS 6400 The main incentive of the voluntary lsquoAAAAArsquo scheme
61
has been the publicity and cash rebates offered by water utilities However the coverage water efficiency performance requirements and impact of this program have been limited
In 2003 the Environment and Heritage Ministers agreed to implement a national Water Efficiency Labelling Scheme (WELS) for products such as shower heads washing machines dishwashers and toilets Consultation with industry and stakeholders was undertaken in 2003 with a strategic study published that identified the products to be included in the new labelling Scheme A Regulation Impact Statement (RIS) which identified the costs and benefits of various options and made various recommendations was published in March 2004 Following public review of the RIS some modifications were made to WELS
The WELS Scheme is backed by the following legislation and standard
Water Efficiency Labelling and Standards Act 2005 which establishes
bull the products subject to the Scheme and the requirements for registration and labelling
bull the standards to apply to WELS products setting requirements for water efficiency performance registration and labelling of these products
bull enforcement provisions including penalties bull the appointment of inspectors to investigate possible contraventions and sets
out their powers and obligations bull review and dispute resolution bull a program Regulator bull the making of regulations bull a requirement for annual reports and for an independent review after five years
Water Efficiency Labelling and Standards Regulations 2005 which
bull prescribes the circumstances in which a person other than the manufacturer of a WELS product may be taken to be the manufacturer of the product (eg an importer)
bull sets out procedures for the issuing and the payment of penalty infringement notices as an alternative to prosecution for offences against the WELS Act
bull specifying the information to be included on an identity card issued to a WELS inspector
Water Efficiency Labelling and Standards Determination 2005 amongst other things determines and establishes product registration fees and calls up the Australian Standard ASNZS6400 2005 Water-efficient products - Rating and labelling which
bull defines the products
bull specifies the assessment procedures (ie identifies test procedures in other Australian Standards)
bull provides the formulas to give products their star rating
bull specifies the labels and their application to products
62
Approximately twenty organisations were represented on the Standards Committee that developed the Standard
State and Territory legislation
The States and Territories have also enacted or agreed to enact complementary legislation to ensure that the WELS Scheme has comprehensive national coverage State and Territory legislation which is almost a mirror of the Commonwealthrsquos Water Efficiency Labelling and Standards Act 2005 enables the States and Territories to for example undertake certain responsibilities delegated to them by the Commonwealth Regulator appoint their own inspectors and enforce the WELS
Other features of WELS include
bull A product web database
bull With the exception of toilets no other products are required to meet mandatory water efficiency requirements (WES) but this may change over time The introduction of mandatory WES means that products not meeting the minimum performance requirements can not legally be sold
bull Products must be tested in accordance with the relevant Standard and must meet any minimum performance and water efficiency requirements in the Standard before they can be granted a WELS Water Rating label
bull It is up to manufacturers or their agents (eg importers in the case of imported products) to ensure that their products are correctly registered and labelled and comply with any other requirements of the Standard
There is a transition phase which gives manufacturers and importers time to test register and label products and to sell pre-existing stock From 1 January 2008 all products are required to display the WELS Water Rating labels irrespective of their date of supply
63
The WELS Water Rating label
Label Features
bull A star rating for a quick comparative assessment of the models water efficiency
bull Labels with 1 to 6 stars
bull Some products may also be labelled with a Zero Star Rated label which indicates that the product is either not water efficient or does not meet basic performance requirements
bull A productrsquos water consumption figure
bull There are provisions for swing tags if there is inadequate surface area for label or the item is likely to be marked by sticking the label on the product
Summary Mandated product labelling using lsquostarrsquo rating system Has a disendorsement label and has provisions to ban products
33 Gas Appliance Rating Scheme
Purpose
A gas labelling program to improve the energy efficiency of gas powered products
Background and Strategy
The Gas and Fuel Corporation of Victoria introduced energy labelling for gas water heaters in 1981 This scheme was taken over by the AGA in 1985 who in 1988 introduced a six star energy performance label This label was intended to be visually consistent with the star rating labels already familiar to consumers of electrical appliances
The labelling scheme is currently voluntary and still administered by the industry body
A range of gas appliances have been subject to minimum energy performance standards (MEPS) since the 1960s The current MEPS levels were set in 1983 and

34 Green Vehicle Guide
Purpose
To provide web-based comparable and accessible environmental data on new motor vehicles
Background and strategy
65
The Commonwealth government started publishing a booklet of fuel consumption data for new passenger and light commercial vehicles in the early 1980s and a low cost web database in more recent years
In 2004 the Government through the Department of Transport and Regional Services (DOTARS) expanded the fuel consumption guide into the Green Vehicle Guide The Green Vehicle Guide is a web based database that rates new passenger and light commercial vehicles on air pollution greenhouse emissions and fuel consumption and gives an overall lsquostarrsquo rating for each vehicle within each vehicle category (small medium luxury sports etc)
The data on which the scores are derived are provided voluntarily by the vehicle manufacturers however this data is based on mandatory Australian Design Rule certification test data
The Guide uses a 5 star rating system however it also assigns half stars resulting in a total of 10 levels
The Greenhouse Ratings are based on carbon dioxide emissions and the Air Pollution Ratings take into account the relative environmental impact of oxides of nitrogen hydrocarbons and particles The relative harmfulness of the pollutants (shown in table below) has been quantified based on the allowable concentrations under the Ambient Air Quality National Environment Protection Measure (NEPM)

NOx and HC were given equal final weightings despite the slight difference in the calculated relative harmfulness primarily because under ADR7900 a combined HC+NOx limit is prescribed rather than individual limits for each pollutant
The higher weighting for particulate matter recognises its significant health impacts The Air Pollution rating scale was devised in such a way that a lsquotypicalrsquo car (that is most petrol engined passenger cars meeting the current emission standard at the time) receives a mid-point rating (5 out of 10)
66
The overall rating or stars is derived from the sum of the air pollution and greenhouse scores ie they are equally weighted
Development of the Green Vehicle Guide (see extract below) involved extensive consultation with vehicle manufacturers
Website Costs
The new highly automated web database which contains data on approximately 1400 vehicles and has sophisticated search facilities cost approximately $200000 to develop plus around $100000 was spent recently to improve the sitersquos usability This compares to the previous low cost database which together with the printed guide cost less than about $80000 per annum The low cost version lacked the automation was only updated annually and did not have the ability to compared vehicles
The manufacturers provide the data on line using special access codes This data is checked by DOTARS before it is uploaded onto the website It takes close to a full time position within DOTARS to administer the website and respond to website related queries
Market Research and Marketing
Before the new greenvehicleguidegovau website was launched DOTARS commissioned consumer surveys to determine the level of knowledge about the environmental impacts made by vehicles This research showed that around half of those surveyed had the belief that ldquoall new cars have the same level of impact on the environmentrdquo
It became apparent through the surveys that there was a need to provide consumers with meaningful information on the relative performance of different vehicles This was a view shared by the Productivity Commission who said that while markets provide extensive information to consumers regarding fuel consumption of motor vehicles ldquothe Australian Governmentrsquos Fuel Consumption Labelling Scheme and Green Vehicle Guide provide relatively low cost accessible and comparable information to consumers and may be justified as part of the more fundamental objective of encouraging consumers to reduce the adverse environmental impacts of motor vehicle userdquo The Productivity Commission also commented that government
67
sources of information of this type were seen as credible and reliable and held in higher regard than information provided by others
DOTARS has scheduled some follow up consumer research for 200062007
DOTARS has spent about $600000 in marketing the Green Vehicle Guide This has included advertising in weekend guides in newspapers developing facts sheets plus targeted marketing to motor vehicle journalists
Summary Website - voluntary but legislative base
4 Government-Industry Partnership programs
Government-Industry Partnerships are the basis of many environmental initiatives and can take a number of forms Industry and government negotiate the terms of the program which are normally detailed in a formal agreement which sets out the environmental objectives and the responsibilities of each party towards their achievement
The GovernmentIndustry Partnership programs outlined below indicate the varied nature of these initiatives
41 The National Packaging Covenant
The National Packaging Covenant (the Covenant) commenced in 1999 and is a voluntary agreement between all levels of government and companies throughout the packaging chain including raw material suppliers packaging producers and retailers The Covenant commits signatories to the implementation of best practice environmental management in areas such as packaging design production and distribution and research into life cycle issues Signatories to the Covenant produce action plans on the measures they will implement to reduce packaging waste and they report annually on their progress In this sense the Covenant provides flexibility to signatories to develop plans suitable to their own circumstances The Covenantrsquos success (it currently has over 600 signatories) is due to the active promotion of it by Government and key industry players
The Covenant is complemented by a regulation the National Environment Protection (Used Packaging Materials) Measure (the NEPM) which enables states and territories to use enforcement action to require companies that donrsquot sign the agreement to take steps to reduce their packaging waste Preceding the Covenant and the NEPM were a number of voluntary industry agreements but these were limited in scope and largely focused on companies in the beverage industry
42 National Industry Reduction Agreement
The Publishers National Environment Bureau (PNEB) was formed in 1990 as an association of the major publishers of newspapers and magazines in Australia to promote the recovery and recycling of old newspapers and old magazines primarily from community kerbside collections organised by local councils
68
The PNEB and a newsprint manufacturer have voluntarily entered into a series of five-year Industry Waste Reduction Agreements with the Commonwealth and State Governments Under the current (third) plan 2001-2005 newsprint recycling in Australia has grown to 754 nationally in 2005 from the 28 level when the PNEB was formed in 1990
43 StateLocal target based programs
There have been a number of agreements signed by state government departments and an industry group where there is a stated goal to reach a specific environmental target For example in the early 1990s there was a voluntary agreement with the EPA Victoria and companies in the Altona Chemical Complex in the western suburbs of Melbourne (which includes Australian Vinyls BASF Dow Chemicals and Qenos) to reduce hydrocarbon emissions by 50 within a specified timeframe The target was met and further emissions reductions were negotiated The NSW EPA-Oil industry petrol volatility agreement outlined below is another example of a target based program
44 NSW EPA-Oil Industry Memorandum of Understanding on Summer Petrol Volatility
In 1998 NSW established arrangements for the supply of low volatility petrol in summer in the Sydney Greater Metropolitan Region implemented through a Memorandum of Understanding between the then EPA and oil companies The principal reason for controlling petrol volatility in summer is to reduce evaporative emissions of VOCs (from vehicles and production and storage sites) which contribute to ozone formation
The Memorandum of Understanding operated over four summer periods from 1998 to 2002 and involved companies voluntarily reducing petrol volatility (measured in kilopascals (kPa) of vapour pressure) over three summer periods from a base of 76kPa to 70kPa in the first summer 67kPa in the second and 62 kPa in the last two years
Although the Memorandum of Understanding was successful in progressively reducing petrol volatility over the period of its operation it was not supported by all industry members Consequently agreement was reached with industry that summer petrol volatility limits should be regulated to ensure a level playing field for all industry participants and regulated limits will apply from the summer of 200405

Appendix 3 Productivity Commission Comments on Labelling and Minimum Performance Standards
The Productivity Commission an independent agency which is the Australian Governmentrsquos principal review and advisory body on microeconomic policy and regulation recently examined the cost effectiveness of improving energy efficiency As part of its review lsquoThe Private Cost Effectiveness of Improving Energy Efficiencyrsquo it examined labelling programs minimum mandatory energy efficiency requirements and other means of providing consumer information The final report contains some highly relevant material that is applicable to establishing a benchmarking scheme for small engines
The following is a summary of relevant conclusions from the Inquiry
Government Operated Labelling Schemes
From consumer research provided to the Commission it concluded that ldquothere is some evidence to suggest that consumers are now paying more attention to labels than they have in the pastrdquo
The Commission was positive about labelling programs as labels
bull directly address ldquoa source of market failure mdash the asymmetry of information between buyers and sellers of energy-using productsrdquo
bull provide information to the consumer that is readily-accessible and easily-understood and therefore can assist in helping the consumer make better-informed choices
bull are likely to have produced net benefits for consumers
bull do not directly limit consumer choice
bull could provide a greater incentive for suppliers to sell products that use energy cost effectively
bull probably produced net social benefits
bull are most suited where there is a wide spread in the range of performances of comparable appliances and where information failures are most pronouncedrdquo
bull can be used to warn consumers that an appliance is very inefficient (through a disendorsement label) which could be effective in discouraging but not preventing consumers from buying the poor performing product
The Commission was supportive of Governmentrsquos role of drawing together and packaging information through labelling programs as this ensures that ldquorelevant and trusted information gets to those who would otherwise not get itrdquo In material reviewed by the Commission George Wilkenfeld and Associates and Energy Efficient Strategies (1999) claimed that labelling is unlikely to be effective if purchasers rarely inspect appliances in a showroom where they can compare performance across
71
different models or the purchaser is not the ultimate user and so has little interest in operating costs
Labelling programs involves both administration and compliance costs such as those incurred by suppliers in having their products tested but the Commission considered that labels should be more actively considered as an alternative to minimum performance standards
Minimum Performance Standards
Governments can prevent the sale of inefficient products by using minimum standards for example the Minimum Energy Performance Standards (MEPS) that apply to appliances such as refrigerators and freezers air conditioners and electric water heaters If appliances do not meet the minimum standard they cannot be sold in Australia Some appliances are covered by both MEPS and by labelling (for example refrigerators)
The Commission considered that MEPS and labels can be complementary as MEPS act to penalise the worst energy performers whereas labels rewarding the better performers
Costs comparisons of schemes
The Department of the Environment and Water Resources provided details about the costs involved in administering both the labelling scheme and the minimum performance standards for energy programs It stated that
bull the administration costs of MEPS are substantially lower than for labelling but the compliance costs can be higher
bull MEPS can have a greater cost for suppliers than labelling since suppliers must adjust their model ranges to meet the MEPS levels by the given date These compliance costs are however influenced by the lsquolead inrsquo time between the introduction of the regulatory proposal and the implementation of the MEPS
bull it is estimated that the administration costs for MEPS would be $3 million over the period 2000ndash15 compared to $39 million for labelling (in present value terms) (George Wilkenfeld and Associates and Energy Efficient Strategies 1999) Furthermore it was assumed that 84 per cent of administration costs were borne by appliance purchasers with the remainder borne by governments
It estimated that MEPS would increase the cost of appliances by $266 million over 2000ndash15 compared to $688 million for labelling (the latter cost being due to consumers voluntarily purchasing more efficient appliances)
