WHICH REPORT?

The findings from this research project are presented in five reports. This page is intended to guide

you towards the report that will be of greatest use for you. There is a synthesis, or summary report,

looking across the whole project. This is supported by a detailed report on the findings from each of

the three phases of the research, each of which presents a brief method statement and an

explanation of the underlying theory.

In addition there is a technical annex which provides a detailed method. It includes materials

relevant to the context or delivery of the project which would be required to repeat the approaches

used, but which are too lengthy or detailed for inclusion in the main reports, for example, the

scoping review search strategies and focus group topic guide.

Synthesis Report

This report moves towards an understanding of what makes an effective model for reward and

recognition schemes intended to encourage household waste-related behaviour change by drawing

on all three phases of the research. It draws out key practical implications for those involved in

developing, delivery or implementation of waste-related reward and recognition schemes.

Phase 1 Report: Scoping review of evidence on the use of reward and recognition schemes in

enhancing recycling and waste prevention behaviours

This report would be of most use for those interested in the detail of the evidence available

specifically related to waste-related behaviours.

It presents the findings from the Phase 1 of the project - a scoping literature review - which

identified and synthesised existing evidence on the role of reward and recognition schemes in

changing household waste behaviours.

Phase 2 Report: Scoping review of evidence on the use of reward and recognition schemes in

enhancing non-waste behaviours

This report, on the evidence from a literature with widened scope, would be of most use to those

interested in the wider evidence about the effectiveness of reward and recognition schemes in

changing behaviour.

There is a brief summary of cross-cutting findings, drawing out lessons applicable to household

waste-related behaviour change. The main body of the report consists of a series of mini-reviews

summarising the evidence identified in each behavioural area, which were: health, education,

volunteering and sustainable use of: food, water, transport and energy, volunteering.

Phase 3 Report: Case studies and focus groups exploring waste-related reward and recognition

schemes

This report would be of most use for those looking for descriptions and participant experiences of

real-world reward and recognition schemes to understand strengths and weaknesses of potential

models. Five case studies were developed, complemented by focus groups involving participants of

some of the case study schemes.

KEY LEARNING POINTS FOR REWARD AND RECOGNITION SCHEMES

This project has identified the following key learning points for the delivery of reward and

recognition schemes which are successful at encouraging recycling. They draw on two literature

reviews, five case studies and six supplementary focus groups conducted during the project, details

of which are given in the full technical reports and annexes accompanying this Synthesis Report.

PUBLIC ENGAGEMENT, OUTREACH AND FEEDBACK

The evidence reviewed emphasises the importance of providing publicity, information and feedback

alongside the rewards in order to show residents exactly what recycling they are required to do, why

they should be doing it, and how to do it (Maunder et al., 2003). This may be in the form of leaflets,

fact sheets, feedback cards, recycling guides, newsletters, advice hotlines, public service

announcements, booths at community events, or websites.

Public engagement

The types of rewards or recognition must be tailored to local concerns and interests. Public

engagement prior to and during the roll-out of any reward or recognition scheme is essential to

identify the types of rewards that carry the greatest motivational appeal for the target group, to

understand how best to appeal to their broader lifestyle attributes, provide credible branding, and

inform and provide choice through targeted messaging (Iyer and Kashyap, 2007; Maunder et al.,

2003). The tone of communications needs to be carefully considered, ensuring the use of consumer-

friendly language, and bearing in mind local cultural identities (Brook Lyndhurst, 2009).

Participants in the focus groups called for a choice of rewards. Each focus group, be it with new or

existing recyclers, included a mix of participants who felt more motivated by community-based

rewards and those calling for better and more appealing rewards for individuals.

Tailored feedback

The literature highlighted that incremental and carefully tailored feedback delivered at the point of

service can have a valuable influence on recycling rates (Harder and Woodard, 2007; Nomura et al.,

2011; Schultz, 1999). The need for regular communication and feedback was also noted (Brook

Lyndhurst, 2009; London Assembly, 2011a; Timlett and Williams, 2008), in part to overcome the

natural tendency for participation to plateau over time following the implementation of any

intervention, and in part to overcome the challenge of population transience.

Woollam et al. (2003) note the importance of providing positive feedback that recognises

community and individual household achievements. This was also an important finding to emerge

from the Phase 3 focus groups, in which participants emphasised the importance of hearing about

the positive community benefits of their actions.

Positive publicity

Based on the 2006 evaluation of Defra’s Household Waste Incentive Pilots, AEA Technology (2006)

emphasise the need to inspire positive publicity, for example in the local media and amongst

relevant stakeholders, which will serve to advertise the reward being offered, motivate people to

participate through recognition of it being a joint effort, maximise campaign reach, and recognise

Page 6: Synthesis Report: Review of evidence on the use of reward ...psi.org.uk › pdf › 2015 › reward_and_recognition-SynthesisReport.pdf · developing, delivery or implementation of

3

and reward people for ongoing success. This links to the findings of Mitchell and Maunder (2005)

that the success of local authority-run voluntary reward schemes relies upon significant commitment

from support partners, such as charity partners coordinating the delivery of community rewards.

EXISTING INFRASTRUCTURE

Any successful scheme, whether reward-based or not, needs to be underpinned by comprehensively

planned, well-developed, and interconnected waste infrastructure (Fogarty et al., 2008). Reward

schemes intended to motivate engagement and raise awareness but that do not provide the

necessary supporting infrastructure will lead to a frustrated target audience unable to carry out the

intended action. Similarly, a poorly-promoted scheme with an excellent delivery system in place will

likely result in a lack of understanding and commitment (AEA Technology, 2006; London Assembly,

2011b; Maunder et al., 2003).

INTEGRATION INTO A WASTE MANAGEMENT STRATEGY

The ad hoc nature of many incentive schemes (AEA Technology, 2006; Mitchell and Maunder, 2005),

relying upon staff time, creativity and enthusiasm has meant that schemes were rarely properly

integrated into wider household waste prevention approaches, nor was there any systematic

monitoring or evaluation of the schemes. Local authorities contacted as part of that research

(Mitchell and Maunder, 2005) suggested that greater understanding of the longer-term impacts of

such schemes relied upon more secure, long-term funding for scheme implementation, integration,

monitoring and evaluation. This need for more robust evaluation of future reward and recognition

schemes was a clear conclusion to emerge from both the Scoping Reviews and the case studies.

PEOPLE WANT TO SEE THEIR EFFORTS MATCHED BY GOVERNMENT AND

INDUSTRY

Though not a new finding, a clear message from the literature reviewed is that consumers need to

feel that responsibility does not rest with them alone, as reflected in calls for greater producer and

retailer responsibility and reduction of waste at source (Maunder et al., 2003; Granville and

Mulholland, 2006). Common frustrations mentioned in the Phase 3 focus groups concerned the

barriers to recycling, reuse and repair resulting from irresponsible industry practices.

Box 1: Action plan for local authorities considering a new reward or recognition scheme

1. Undertake research locally to understand lifestyle trends and their impacts on the waste stream, and to identify the key barriers to improved recycling performance;

2. Identify the target audience and define measurable targets and objectives for a new scheme that will best address these barriers and appeal to the target audience;

3. Develop key messages to sell the benefits of a new scheme;

4. Engage stakeholders and partners to initiate and inspire action;

5. Ensure the necessary infrastructural and administrative support is available to the scheme;

6. Implement the scheme;

7. Monitor, review and evaluate regularly to quantify and ensure ongoing effectiveness of the scheme;

8. Feedback success to maintain motivation.

EXECUTIVE SUMMARY

This Synthesis Report presents an overview of the findings from the project ‘Review of evidence on

the use of reward and recognition schemes in enhancing recycling and waste prevention behaviours’

(EV0528). The project was commissioned by Defra to explore the effectiveness of reward and

recognition schemes in promoting waste-related pro-environmental behaviour and was conducted

by Policy Studies Institute (PSI). It follows a commitment in the Coalition Government’s Plan for

Government to ‘encourage councils to pay people to recycle’ (HM Government, 2010: 17), and the

launch of several high-profile schemes which seek to encourage recycling through individual and

community rewards.

The key objective of the project was to assess critically and summarise the existing evidence about

the role of reward and recognition schemes in influencing behaviour, in particular, recycling and

waste prevention behaviours. The project aimed to identify and synthesise the existing evidence on

reward and recycling schemes in changing waste-related and recycling behaviours and also transferable

lessons from schemes focused on non-waste behaviours.

The central research question for the project was: How effective, and cost-effective, are reward

and recognition schemes in changing behaviour? The project sought to explore the context in which

rewards and recognition schemes have been administered to understand what works for which

behaviours, with whom, when and in conjunction with which other policy tools. Where possible, the

cost-effectiveness of reward and recognition schemes was explored.

Research Method

A phased approach was adopted in the research, with the findings of the first phase determining the

nature of activities undertaken in the second. The four overarching research tasks included:

Phase 1 Scoping Review: To identify and synthesise evidence on the role of reward and

recognition schemes in influencing recycling and waste prevention behaviours. Of 440 sources

identified, 74 were shortlisted for inclusion, 37 of which were used to inform the review.

Phase 2 Scoping Review: To identify and synthesise existing evidence on the role of reward and

recognition schemes in influencing non-waste related behaviours, focusing explicitly on non-

waste pro-environmental behaviours (sustainable transport, energy, water and food

consumption) and volunteering and those relating to health and education. Of 364 sources

identified, 119 were used to inform the review.

a. Phase 3 Case Study Analysis: Five exploratory case studies were undertaken in order to: capture

learning from current or recent recycling reward schemes which is not yet available within the

published literature; to understand the extent to which these schemes are being evaluated and

opportunities for an improved approach to evaluation in future schemes. The case studies

included: (1) a community Recycling Reward Scheme in Ealing, London; (2) a food waste

recycling feedback trial in Oldham, Manchester; (3) the Marks and Spencer/Oxfam Clothes

Exchange, nationwide; (4) the Golden Ticket scheme, rewarding household recycling

participation with equipment for local schools in Wythenshaw, Manchester; and (5) a scheme

offering individual rewards, ‘Recyclebank’, run in the Royal Borough of Windsor and

Maidenhead, in Halton, and more recently in Lambeth in London.

b. Focus Groups: to complement the findings of the reviews and case studies, six focus groups

were held with participants of three of the schemes included in the case study analysis. These

aimed to explore participants’ perceptions of and responses to rewards, and how these vary

between low and medium-high recyclers.

The project was a scoping study, intended to gain an initial understanding of the state of the existing

evidence base, and to use this evidence to highlight emerging research needs and opportunities for

these to be addressed within ongoing and future reward and recognition schemes. As such, the

findings are limited by the quality of the existing evidence available.

Considerations for future reward and recognition schemes

The evidence base on the use of rewards and recognition to influence behaviour is currently patchy

and incomplete. In relation to waste, much of the research and policy effort has focused on recycling

rather than wider waste prevention activities such as repair, reuse and waste reduction.

Across the non-waste pro-environmental behaviours, there is: most evidence on the use of rewards

in the fields of health and, to a lesser extent, education; very limited evidence of the use of rewards

or feedback to influence sustainable water consumption or food-related behaviours; growing

evidence of the use of rewards to encourage sustainable transport (though this has not been widely

captured in the peer-reviewed academic literature); and significant evidence of the use of feedback

(but not rewards) to influence household energy conservation behaviour.

Based on the evidence reviewed within both Scoping Reviews and the Case Studies, and the issues

raised during the focus groups, we highlight conclusions for researchers, practitioners and policy-

makers engaged in current and future reward and recognition schemes or trials. Given the significant

evidence gaps identified we also highlight opportunities for future research and evidence gathering

on reward and recognition schemes.

Isolating the impact of rewards or recognition. There is a lack of robust evidence that successfully

isolates the specific impact of rewards or feedback on recycling and waste prevention behaviour

from the confounding impacts of accompanying activities such as communications, and

infrastructure improvements. Future reward or recognition schemes would benefit from more

rigorous evaluation approaches, ideally using randomised or matched control groups.

Understanding the differential effects of rewards on recycling compared to wider waste

prevention activities. There is some indication from the non-waste literature that rewards are most

effective in influencing simple, infrequent behaviours, or in encouraging initial engagement in more

complex habitual behaviours, with additional support needed to sustain engagement. Future trials

could usefully evaluate the influence of rewards and/or feedback on more infrequent repair and

reuse decisions in comparison to routine, habitual recycling activities.

Understanding which rewards are the most salient for different target groups. Greater public

engagement is needed prior to rolling out any future reward or recognition scheme to understand

which rewards will be most salient to the target populations and what additional support they may

need. Does the value of the reward matter? Are there thresholds in reward value at which different

groups respond? Or are certain groups more likely to respond to rewards? Does the framing of the

reward matter – how can they be presented to acknowledge achievements without creating an

expectation of additional rewards in response to sustained behavioural changes in the future?

Public awareness of waste disposal and recycling costs. Mentioned in the literature and focus group

participants was a feeling amongst the public that if they are recycling more, this should be reflected

Page 10: Synthesis Report: Review of evidence on the use of reward ...psi.org.uk › pdf › 2015 › reward_and_recognition-SynthesisReport.pdf · developing, delivery or implementation of

in their council tax bills. At the same time, there were calls for a more comprehensive recycling

service, in which more materials are collected. This tension between a desire for reductions in

council tax alongside the provision of a more comprehensive (and therefore expensive) kerbside

recycling service could usefully be explored further.

Measuring performance. Focus group participants noted the importance of fairness when designing

schemes. Concerns were raised, for example, that weight-based schemes effectively penalise

individuals who are making waste reduction decisions at the point of purchase and smaller

households who will likely generate less recycling. At the same time, the literature reviewed notes a

lack of conclusive evidence concerning the impact and cost-effectiveness of reward or feedback

schemes that are based on contamination rates rather than weight. This suggests a need for future

schemes to trial the effectiveness and cost effectiveness of rewards for recycling the correct items

and/or for reducing waste, rather than relying solely on weight-based or self-report systems.

Are rewards needed or is recognition sufficient? Whilst both reviews identified studies that have

explored the behavioural impact of providing feedback to study participants, very few studies were

identified that evaluated the impact of tangible rewards in comparison to the impact of feedback. Do

all individuals need a tangible reward or is verbal/written recognition sufficient? What is the

potential for introducing award-based schemes where rewards deliver reputational – rather than

tangible monetary or gift-based – benefits?

How can reward and recognition schemes be designed to encourage spillover? Very little evidence

was identified that explored the potential for rewards or recognition to influence behaviours beyond

the primary target behaviour (‘spillover’). The Phase 2 Review suggested that competition-based

schemes tend to attract those who are more ‘ecologically conscious’ who are more likely to

demonstrate spillover behaviours. Further research could explore the potential to use competition-

based models to encourage spillover behaviours amongst medium or high recyclers.

Do reward schemes promote consumption? A concern that is commonly raised in response to

proposals to introduce reward schemes is that monetary rewards could promote increased

consumption and thereby enhance waste generation. Neither review found any studies that have

explored this systematically; a gap which could usefully be addressed within evaluations of future

reward schemes. If schemes are seen to be increasing consumption, further research could explore

how such schemes could be redesigned to avoid such increases.

Longevity of behaviour change. Our reviews found very little research exploring the longevity of

behaviour changes triggered by different types of reward or feedback schemes. There is a need to

include a resource allocation for longer-term monitoring in evaluation budgets, and to identify how

best to sustain longer-term changes in behaviour following the implementation of a reward. Is it

better to reincentivise or to communicate with and educate residents continually to maintain their

interest in preventing waste?

Targeting moments of change. Though not a focus of this work, one area for further research is the

potential to target rewards on individuals undergoing transitions and moments of change, for

example new residents in an area who have not yet established their routines and habitual

behaviours. The potential for taking advantage of such windows of opportunity could usefully be

explored in future reward/feedback schemes, particularly given the finding in the existing literature

that highly transient populations are often harder to engage in recycling initiatives.

1. INTRODUCTION

This Synthesis Report presents an overview of the findings of the Defra-funded project undertaken

by Policy Studies Institute (PSI); ‘Review of evidence on the use of reward and recognition schemes in

enhancing recycling and waste prevention behaviours’ (EV0528). The project was commissioned to

explore the effectiveness of reward and recognition schemes in promoting waste-related pro-

environmental behaviour. It follows a commitment in the Coalition Government’s Plan for

Government to ‘encourage councils to pay people to recycle’ (HM Government, 2010), and the

launch of several high-profile schemes which aim to encourage recycling through rewards.

While waste composition analysis suggests that over two-thirds of the UK’s household waste (68%)

can be recycled or composted (Parfitt, 2002) and the amount of UK waste sent to landfill has

gradually decreased in recent years, the actual proportion of household waste that is recycled,

composted or re-used remains at 40.1% (Defra, 2011a). A variety of approaches have been used to

encourage recycling and waste prevention, such as improved kerbside infrastructure, education to

reframe waste as a resource, communication and feedback, leading by example, and taxes and

charges (disincentives) (Pocock et al., 2008).

Far fewer examples are apparent of the use of positive incentives - rewards and recognition - in

encouraging recycling and waste prevention behaviours (Harder and Woodard, 2007; Shaw and

Maynard, 2008; Timlett and Williams, 2008). The schemes that have been implemented tend to be

small, short-term pilots (AEA Technology, 2006; Maunder et al., 2003), primarily focused on recycling

rather than wider waste prevention behaviour. This project was therefore intended to identify,

assess and summarise the available evidence on reward and recognition schemes.

In this Synthesis Report, we briefly describe the project’s aims and methods, summarise the theory

underpinning reward and recognition schemes, present the cross-cutting findings from the evidence

gathered, and conclude with a discussion of the potential for future schemes to address gaps in the

evidence base on the use of reward and recognition schemes to influence recycling and waste

prevention behaviour.

What do we mean by ‘positive incentives’?

Incentives may be classified as ‘antecedent’ or ‘consequence’ intervention strategies (Abrahamse et

al., 2005). Antecedent incentives are provided prior to the performance of the desired behaviour, and

are assumed to work by influencing determinants of that behaviour, for example, offering new

residents a free bus pass to give them means to ‘test’ the local public transport system. Consequence

incentives are provided after the performance of the desired behaviour in order to ‘reward’ that

behaviour and encourage its continued performance (Breukers et al., 2009). Consequence incentives

may be provided unexpectedly following the behaviour, or promised beforehand in an effort to

motivate the behavioural change. They may be provided purely for engaging in a desired behaviour, or

could be contingent on achieving specific outcomes. They may involve tangible gifts (cash or

equivalents) or may constitute a more symbolic verbal reward (otherwise known as ‘positive

feedback’). Each of these differences has important implications for how incentives are perceived by

recipients and for how they do or do not influence behaviour. This project focused primarily on the use

of consequence incentives, which reward or recognise participation in a desired behaviour, rather than

directly enable it. However, a number of the schemes are accompanied by changes in the collection

systems for waste and recycling or approaches to communication with target participants.

2. PROJECT AIMS AND RESEARCH QUESTIONS

2.1 AIMS

The key objective of this project was to assess critically and summarise the existing evidence about

the role of reward and recognition schemes in influencing behaviour, focussing on schemes targeted

at recycling and waste prevention behaviours in particular. The project aimed to identify and

synthesise the existing evidence on reward and recycling schemes in changing waste-related and

recycling behaviours and also transferable lessons schemes focused on non-waste behaviours.

The project sought to explore the context in which rewards and recognition schemes have been

administered to date to understand what works for which behaviours, with whom, when and in

conjunction with which other policy tools. Where possible, the cost-effectiveness of reward and

recognition schemes was explored.

2.2 RESEARCH QUESTIONS

The overarching research question kept in mind throughout each phase of the project was:

How effective and cost-effective are reward and recognition schemes in changing behaviour?

Beneath this lay a number of more specific research questions:

1. Which types of rewards are likely to be most effective for which behaviours?

2. How does the effectiveness and cost-effectiveness of individual rewards compare with collective

rewards?

3. What context-specific issues help or hinder the success of reward and recognition schemes?

4. What package of approaches is more likely to lead to the success of the scheme, including most

effective mechanisms for communicating feedback?

5. What are the effects of rewards and/or feedback on people who may already be engaging in a

particular behaviour and what do the most successful schemes do to encourage those already

participating to continue to do so?

6. Is there any evidence of adverse outcomes of such schemes, such as increasing consumption

trends with greater purchasing power?

7. To what extent is the impact of any reward or feedback scheme limited over time? What does

the evidence suggest is likely to be effective in helping embed new behaviours over time?

3. THE THEORY BEHIND REWARDS AND RECOGNITION

In this section, as context to the following sections, we introduce the theories informing the way in

which rewards and recognition are expected to influence behaviour, drawing on the literature from

both scoping reviews. Full details are available in the accompanying technical reports.

3.1 HOW ARE REWARDS THOUGHT TO INFLUENCE BEHAVIOUR?

Reward-based interventions are based on economic and psychological theories about what drives

human behaviour. From an economic perspective, tangible rewards are assumed to provide extrinsic

motivation through overcoming personal costs (money, time- or effort-related) of undertaking the

desired behaviour or through increasing the financial benefit of doing so. From a psychological

perspective, the promise of a financial reward contingent on performing a specific behaviour is

thought to provide the extrinsic motivation needed to encourage behavioural change amongst those

whose intrinsic motivation is low (Jochelson, 2007). In addition, the provision of a reward can have a

‘signalling’ effect, raising awareness about the importance of the specific behaviour; this

demonstrates the potential ‘attention effect’ of rewards (Breukers et al., 2009).

Much debate surrounds the impact of offering tangible rewards to those whose intrinsic motivation

is already high. Frey’s theory of motivational ‘crowding out’ (Frey and Jegen, 2001) suggests that

extrinsic rewards can serve to ‘crowd out’ or undermine intrinsic motivations, since their

implementation underestimates the influence of wider social context on behaviour and the degree

to which individuals are motivated to act for pro-social reasons (Dobson, 2010). Frey suggests

‘crowding out’ effects could occur when: (a) the external reward is seen as controlling and therefore

lowers an individual’s level of self determination (i.e. their sense of competence, autonomy and

personal commitment), such that intrinsic motivation is substituted by extrinsic control; or (b) an

individual’s intrinsic motivations for participating are not openly acknowledged or appreciated by

the external reward-based intervention (Frey and Jegen, 2001). In the reverse circumstances, that is

when external reward-based interventions are seen as supportive and non-controlling, Frey (2007)

suggests they may ‘crowd in’ intrinsic motivation, through encouraging self-determination and

fostering self-esteem.

Very little research has been carried out to date to explore the existence of crowding out (or

crowding in) in real-world situations. Drawing on the findings of two meta-analyses of laboratory-

based experiments and econometric studies on crowding out (Cameron and Pierce, 1994; Deci et al.,

1999), it is suggested that interventions based on verbal or written feedback to participants may be

more successful in encouraging longer-lasting shifts towards desirable human behaviours. Feedback

may be based on the outcomes of personal behavioural efforts (individual feedback) or on the basis

of collective efforts (group feedback). Feedback may include a comparison, for example with

personal efforts made in the past (historic feedback) or with the efforts made by a meaningful

comparison group, such as other households living along the same street.

3.2 HOW IS FEEDBACK OR RECOGNITION EXPECTED TO WORK?

Darby (2010a), considering the area of energy, notes a range of theories that can provide valuable

insights into the potential mechanisms of feedback-based behavioural interventions, drawing from

those developed in economics, sociology, psychology and education.

The explanation based on the theory of rational economic actors is that energy is a commodity and

consumers will adapt their usage in response to price signals. However, the evidence for this is

mixed; for example, if this mechanism were strong, far greater investment in energy efficiency

measures would be expected in the home following fuel price rises (Darby, 2010a; Hargreaves et al.,

2010). Increasingly, insights from behavioural economics are being applied to feedback-based

interventions, drawing on Thaler and Sunstein’s ‘nudge’ theory, defined as ‘any aspect of the choice

architecture1 that alters people’s behaviour in a predictable way without forbidding any options or

significantly changing their economic incentives’ (Thaler and Sunstein, 2008: 8, cited in House of

Lords, 2011). The provision of norm-based feedback could be considered a ‘nudge’ as it exploits

individuals’ natural tendencies to measure the appropriateness of their behaviour through assessing

how far they are from a prevailing social norm and adjusting their behaviour accordingly.

A perhaps more holistic view may be gained from sociological theories, which recognise that many

of the challenges in encouraging household energy conservation stem from the fact that energy use

is largely invisible, occurs through the performance of habitual, routine practices that are hardly

reflected upon in everyday life, and is shaped and constrained by complex socio-technical systems

and prevailing expectations of comfort (Darby, 2010a; Marechal, 2010; Shove, 2003 cited in Ellegård

and Palm, 2011). ‘Practice theory’ suggests that providing frequent and relevant feedback on energy

use can ‘make consumption visible, bring it more within the perceived control of the energy user, and

demonstrate the success or otherwise of different actions, behaviour patterns and investments’

(Darby, 2010a). Such sociological theories highlight the limitations of single, standalone

interventions for achieving sustained change in the long-term; interventions need to address the

wider socio-technical system in which energy use decisions are made.

Drawing on psychological theories, feedback may be expected to work through enhancing

individuals’ self-efficacy with respect to conserving energy (Abrahamse et al., 2005; Bandura, 1986

cited in Grønhøj and Thøgersen, 2011). Appropriate feedback is thought to ‘empower’ consumers to

save energy, improving self-efficacy through: (a) increasing and improving individuals’ and

households’ knowledge about their electricity consumption and how it relates to their individual and

collective behaviour; (b) enhancing individuals’ sense of competence, creating ‘mastery experiences’

whereby individuals are able to see positive outcomes of their efforts; and (c) providing additional

social encouragement and support in their efforts (Bandura, 1986 cited in Grønhøj and Thøgersen,

2011). On the flip side, feedback which reveals poor performance could decrease motivation.

Finally, educational theorists highlight that energy users are not a uniform category of learners but a

‘mixed ability, mixed age class’, with differing levels of skill and understanding and varied learning

motivations, and will ascribe different meanings to information (Darby, 2010a). With this in mind,

feedback is thought to have a role in teaching energy and management skills (Darby, 2010a).

Grønhøj and Thøgersen (2011) suggest the success of a feedback system may in part be judged on its

ability to impart improved ‘energy literacy’ to electricity consumers, propagating a ‘virtuous cycle’ of

learning and energy-efficient action.

The rest of this report draws on the two scoping literature reviews, five case studies and six focus

groups conducted during this project to provide a brief summary of the existing evidence on the

effects of tangible rewards and feedback on human behaviour.

4.1 SCOPING REVIEWS

For both reviews, the key elements of Rapid Evidence Assessment (REA) were followed, including a

systematic search strategy, inclusion and exclusion criteria and quality assessment of sources2. The

literature was supplemented by ‘Calls for Information’ through relevant research networks and

personal contact with experts. Details of the methods used can be found in the technical reports and

annex.

PHASE 1 SCOPING REVIEW: WASTE BEHAVIOURS

The aims of the first review were to:

a. Identify and synthesise evidence on the role of reward and recognition schemes in

influencing recycling and waste prevention behaviours;

b. Determine the volume of high quality literature (see discussion below for a definition of

‘high’ quality) on the topic.

Following the screening of 440 titles and abstracts, 74 were shortlisted for full review, with 37 used

to inform the synthesis.

PHASE 2 SCOPING REVIEW – NON-WASTE BEHAVIOURS

In light of the evidence gaps identified in the Phase 1 Scoping Review, a second review (the ‘Phase 2

Scoping Review’), was undertaken in order to:

a. Identify and synthesise existing evidence on the role of reward and recognition schemes in

influencing non-waste related behaviours, focusing explicitly on non-waste pro-

environmental behaviours (sustainable transport, energy, water and food consumption) and

volunteering3 and those relating to health and education4;

a. Highlight opportunities for testing insights gained from these wider behavioural areas in

future waste-related reward and recognition schemes.

Following the screening of sources on the basis of titles and abstracts/executive summaries, 364

articles were shortlisted, 119 of these were used to inform the synthesis. In addition, a number of

initiatives that have not yet been captured in the literature were identified through correspondence

with expert stakeholders5.

Review limitations: While the reviews drew on elements of REA they should be considered Scoping

Reviews. As detailed in the search strategies in the Technical Annex, tight limits were placed on the

search terms, databases and search time-frames, and inclusion and exclusion criteria were applied

to ensure manageable retrieval of data and minimise selection bias. Due to the limited number of

high quality peer-reviewed sources identified, some literature of medium quality was included in the

review, however any quality caveats are clearly indicated.

PHASE 3 CASE STUDIES

The Phase 1 Review was supplemented by five exploratory case studies, which sought to provide

insights into the functioning of existing schemes. The following schemes were selected:

Case Study 1: Recycling Reward Scheme, Ealing, London

Case study 2: Feedback on Food Waste Recycling Trial, Oldham

Case study 3: Marks and Spencer/Oxfam Clothes Exchange

Case study 4: Manchester Golden Ticket Recycling

Case study 5: Recyclebank (Windsor and Maidenhead, Berkshire and Halton, Cheshire).

Multiple data sources were used within each case study to enable methodological triangulation.

Case Studies 4 and 5 (Windsor and Maidenhead only) were also the subject of participant focus

groups to again first hand insights into perceptions and experiences. Descriptions of the five case

studies and other examples of schemes mentioned in this report are given in Annex 1 to this report

and the separate Technical Annex.

Case study limitations: Whilst these sources did provide valuable insights into the schemes, it should

be noted that no robust evaluation data was available for any of the five schemes6. Monitoring data

was provided but without the methodological details needed to assess the reliability of the data; and

also no qualitative research had been undertaken to understand the observed trends, so the

explanations given were based on personal observations from scheme representatives. These

factors significantly limit the potential to draw robust reliable conclusions and the case studies are

therefore only touched on briefly within this Synthesis Report. Their primary value is in reiterating

the need for rigorous monitoring and evaluation of future reward and recognition schemes.

PHASE 3 FOCUS GROUPS

Six focus groups were conducted to explore three schemes from the Phase 1 & 3 Case Study analysis.

These were: 1) the Golden Ticket community reward scheme in Manchester (Case Study 4), and the

Recyclebank reward schemes targeting individuals in 2) Windsor and Maidenhead (one of the

locations of Case Study 5) and, more recently, 3) Lambeth.

The focus groups conducted in each scheme area consisted of 7-10 participants, recruited to ensure

appropriate group composition, in terms of demographics and recycling habits. For each scheme: (i)

one group was held with new recyclers and (ii) another with existing recyclers who already recycled

conscientiously prior to the scheme, driven largely by intrinsic motivation. These groups were

chosen to allow consideration of how perceptions of, and reported responses to, the scheme vary

between low and medium-to-high recyclers, and potentially to explore the existence of any

‘motivational crowding out’ effects. Each focus group lasted 90 minutes. The full topic guide for each

focus group is presented in Annex 5 of the Technical Annex (though the scheme-specific section of

the guide was tailored for each scheme in question). The themes covered may be broadly

summarised as:

Perceptions of the scheme;

Positive and negative aspects of the scheme;

Attitudes to individual versus community rewards;

Appeal of the specific rewards provided and whether or not they are used as a cash

replacement;

The degree to which the scheme has raised awareness/interest in wider waste prevention

behaviours, such as repair, reduce and reuse.

How participants would modify or redesign the scheme to encourage sustained behaviour

change.

Analysis: All focus groups were recorded and transcribed and the transcripts analysed using the

qualitative analysis software, Nvivo 9.

Focus group limitations: The focus groups were not intended to be representative and the findings

should not be generalised to all scheme participants or the general population; the sample size is

small and we recruited only those who are currently recycling and therefore cannot comment on the

perspectives of those who have not engaged in the schemes, or why they may not have done so.

Nonetheless, the findings do provide valuable insights into the scheme attributes that are reportedly

encouraging engagement amongst those who previously reported recycling very little, and highlight

a variety of scheme perceptions and self-reported participant responses to the concept of rewarding

people for recycling, which could usefully be tested in future schemes.

5. EVIDENCE SYNTHESIS

This section summarises the cross-cutting findings emerging from the two Scoping Reviews, the case

studies and focus groups in relation to the project’s research questions7. Whilst acknowledging that

scoping rather than systematic reviews were undertaken, limited high quality evidence8 was

identified on the use of reward and recognition to influence the behavioural areas under review. As

a result, this section includes findings drawn from both high and medium quality sources, but

highlights concerns about quality where appropriate.

Much of the research and policy effort in relation to waste has focused on recycling rather than

wider waste prevention activities. As such, the findings reported in this section primarily relate to

recycling unless otherwise stated.

Findings from the non-waste literature are also included where they highlight potentially useful

hypotheses that could be tested in future waste-related reward and recognition trials. Across the

non-waste pro-environmental behaviours considered, the review identified:

the most peer-reviewed evidence on the use of rewards and incentives in the fields of health

and, to a lesser extent, education;

very limited evidence of the use of rewards or feedback to influence sustainable water

consumption or food-related behaviours;

growing evidence of the use of rewards to encourage sustainable transport (though this has

not been widely captured in the peer-reviewed academic literature); and

significant evidence of the use of feedback (but not rewards) to influence household energy

conservation behaviour (much of which has been peer-reviewed).

Descriptions of the main reward and recognition schemes named in the text are given in Annex 1 at

the end of this report.

5.1 HOW EFFECTIVE ARE REWARD AND RECOGNITION SCHEMES IN CHANGING

BEHAVIOUR?

The evidence available on the use of rewards and recognition to influence recycling suggests their

effectiveness may vary with the type of reward (for example, definite versus probabilistic, individual

versus community rewards – as discussed below), the target group and the reward value.

The Phase 1 Review included seven UK references that reported on surveys exploring attitudes to,

motivations for, or barriers to, recycling. Whilst these surveys track attitudes rather than behaviours

(and are also subject to social desirability bias), improvements to infrastructure and service provision

or to education and communication were more frequently volunteered by respondents than

financial incentives in response to open questions about what would encourage them to recycle

more (Maunder et al., 2003; Pocock et al., 2008). However, positive incentives are consistently rated

more highly than any form of waste charge. Though not peer reviewed, these surveys generally

found that attitudes to recycling reward schemes varied between recyclers and non-recyclers, with

7 The in-depth findings are presented, behaviour-by-behaviour, in the accompanying technical reports.

8 Sources deemed to be of ‘high’ quality included all peer-reviewed journal articles and book chapters. Also included in this

category were government-commissioned reports. However, as with all sources reviewed, care was taken during the data extraction process to note any sources of potential bias (e.g. relating to sampling approach, methods adopted, analysis etc.), together with any concerns about unexplained or unsubstantiated conclusions made within the sources.

some indication that low-medium recyclers tend to perceive rewards more favourably than existing

recyclers (Brook Lyndhurst, 2005 and unpublished).

Within the Phase 3 focus groups, participants conveyed positive perceptions of the use of rewards

for recycling. The low to medium recyclers reported greater recycling effort as a result of the reward

schemes9, even though many participants were yet to redeem the points they had collected10.

Amongst the high recyclers, the self-reported behavioural impact of rewards was limited, but no

adverse impacts were identified. High recyclers tended to see the rewards as ‘something for nothing’

and a positive recognition of their efforts. In particular, in the Maidenhead focus groups, participants

highlighted their appreciation of the Council’s decision to introduce a reward scheme for households

at a time when other councils in the country were introducing fines; ‘that made me feel sort of warm

towards the whole thing and that’s why I got actively involved in it’ [existing recycler, Maidenhead].

Whilst many of these participants were yet to redeem any rewards, it seems the reward scheme

changed the nature of the relationship between the focus group participants and the Council,

making them more predisposed to engage in the scheme.

Little evidence was identified in either Scoping Review that successfully isolates the specific impact

of rewards or recognition from the confounding impacts of additional or related activities - such as

communications campaigns and infrastructure improvements - that typically accompany the launch

of new schemes. Although there is evidence of specific schemes effectively promoting waste

prevention behaviours, there is no conclusive evidence that attributes effect size (that is, the size of

the impact) to the different scheme components (Schultz, 1999). So while the Recyclebank (Case

Study 5), for example, has led to increased recycling participation rates11, it is not clear how much of

this increase is due to the reward scheme itself and how much is a result of the accompanying

communications activity or the fact that participants find the single recycling container easier to use.

We found only one Randomised Control Trial (Nomura et al., 2011) that attributed observed

increases in food waste recycling participation directly to the specific intervention (in this instance, a

short-term feedback trial – Case Study 2).

A finding emerging from the Phase 2 Scoping Review on health behaviours is that rewards appear

most effective in encouraging simple one-off behaviours (Jochelson, 2007; Sutherland, 2008), rather

than more complex habitual behaviours that require sustained and repeated effort. However, it

should be noted that the barriers to changing the health behaviours under study are very different

to those limiting waste-related behaviours; for example, the personal psychological barriers to

engaging in smoking cessation, healthier eating or physical activity programmes are significantly

greater than those preventing participation in recycling or many other household pro-environmental

behaviours such as reducing energy use or purchasing energy-efficient products. The health

literature does suggest that the success of rewards for these more complex behaviours may be in

encouraging initial engagement and discussion, with additional measures supporting sustained

change in the longer-term (discussed below).

9 Though it should be kept in mind that focus groups can only discern self-reported behaviours which do not always reflect

actual behaviours. 10

Given the small sample size, we cannot comment on whether this is true for the wider population of non to low recyclers, particularly since we did not hold groups with those who are still not recycling despite registering for the Recyclebank scheme.

11 As indicated by the recycling rate data recently released: http://www.Recyclebank.com/corporateinfo/index/pressreleasearticle/id/164

17

Though not explored in depth, a small number of sources suggest the actual reward may not be

directly responsible for observed changes in behaviour, but this requires further exploration in

future research. Three studies identified in the health field (Kane et al., 2004; Sutherland et al.

2008), for example, measured significant changes in simple behaviours as a result of a reward-based

intervention, but observed that few participants actually claimed the rewards provided, including

taxi vouchers, free bus passes and clinic fee vouchers. Similarly, in the energy field, few of the

winners of the Dormitory Energy Competition (see Annex 1 for a summary of the trial) attended the

ice-cream party, organised as the prize for the dormitory that achieved the greatest energy use

reductions (Petersen et al., 2007). This aligns with the findings of one recycling reward-based

experimental trial (Harder and Woodard, 2007) highlighted in the Phase 1 Review, which notes low

leisure voucher redemption rates (between 8 and 11%), despite large increases in recycling

participation and no other changes in service provision.

Whilst acknowledging the small sample size, a similar finding was identified in the Phase 3 focus

groups with Recyclebank participants; whilst participants reported collecting their recycling points,

many were yet to redeem the points for actual rewards. In part this was due to the limited appeal of

the rewards currently available and the belief that additional rewards may be introduced to the

schemes in the future. In part, it was due to the logistics of redeeming rewards; for example, those

without access to a printer were discouraged by the delay between choosing the rewards online and

receiving vouchers through the post, and others reported simply forgetting to carry the appropriate

vouchers when shopping.

5.2 HOW COST EFFECTIVE ARE REWARD AND RECOGNITION SCHEMES IN

CHANGING BEHAVIOUR?

Very few sources in either review (or the case studies) discussed the cost-effectiveness of the reward

or feedback intervention under study. The very limited number of recycling-related studies identified

that compared the use of feedback and rewards suggest feedback may be a more cost-effective

mechanism to use, particularly where significant recycling effort is wasted through contaminated

loads (Harder and Woodard, 2007; Timlett and Williams, 2008). However, this result appeared to be

dependent on the mechanism by which rewards and feedback are awarded (e.g. on the basis of

individual versus communal recycling loads, weight-based versus composition-based) Shaw and

Maynard, 2008). Existing research proves inconclusive on whether monetary rewards impact

positively on contamination rates and future research could usefully explore this further.

In the Phase 2 Review, a small number of studies in the areas of health (Kavanagh et al., 2006) and

volunteering (Seyfang, 2003, 2004b, 2006a, 2006b and 2009b) did note the vulnerability of reward-

based schemes to funding cuts or changes in funding priorities. Also highlighted in the health field

was the risk that reward-based schemes tackling long-term complex behaviours can be resource-

intensive as they require constant monitoring and logging of behaviours. On the other hand, a

number of studies, such as the Food Dudes healthier eating intervention for schools (Horne et al.,

2004; Lowe et al., 2004) and the Personal Travel Planning programmes (DfT, 2005; Williamson,

forthcoming), illustrated that rewards need not be large or expensive as long as they are salient to

the recipients and combined with complementary interventions.

5.3 WHICH TYPES OF REWARDS ARE MOST EFFECTIVE FOR WHICH

BEHAVIOURS?

Unsurprisingly, there is no ‘one size fits all’ approach to rewards; different people will respond to

different rewards in different ways depending on the nature of the reward, the behaviour in

question, and the existence or perceived existence of wider socio-technical constraints to change.

Nonetheless, more specific insights can be drawn from the non-waste literature which could be

explored further in future waste-related reward or recognition trials.

Firstly, cash-based rewards may be effective in encouraging simple changes amongst low-income

and/or vulnerable groups, particularly where they lower the financial barriers to entry. This was

apparent in the peer-reviewed health literature relating to the provision of cash rewards to

reimburse the costs (e.g. transport, childcare) of attending immunisation, screening, and pre- or

post-natal care appointments (Jochelson, 2007; Sutherland et al, 2008). It was also observed in the

(non peer-reviewed) Merseyside ‘Let’s Get Moving’ scheme which offered free bus passes and

bicycles to ensure transport affordability for those transitioning from welfare to work (Lucas,

forthcoming). On the other hand, a journal article that explored the impact of providing rebates for

solar panels (Higgins et al., 2011) suggests little uptake by low-income groups, since the panels were

still perceived as too costly even with the rebate. The differential impact of monetary rewards on

low and higher income households was hinted at within the Phase 1 Review (Bennett et al., 2008;

London Assembly, 2011b), but no trials had systematically tested this in relation to waste prevention

behaviours. One peer-reviewed study identified in the Phase 1 Review highlighted that, where

vouchers are used, they need to be redeemable locally and in appealing locations (Harder and

Woodard, 2007).

Based on the limited evidence available, probabilistic rewards (such as prize draw entries) tend to be

less appealing than guaranteed rewards (AEA Technology, 2006; Bennett et al., 2008, Ongondo and

Williams, 2011a), though this may vary depending on the value and nature of the prize (as also

mentioned by the Phase 3 focus group participants). No studies were identified that have

systematically looked into the threshold at which such a prize becomes an effective reward for

changing behaviour.

In relation to recycling, evidence from Europe has found deposit schemes to operate effectively

(Fogarty et al., 2008). Council tax incentives are often favoured by participants in survey-based

studies (a preference also apparent within the Phase 3 focus group discussions), though support

wanes when the likely details of such schemes (particularly the potential value of the rebate) are

explained (Brook Lyndhurst, 2009; Maunder et al., 2003). Whilst we did not identify any recycling-

related experimental trials in which council tax rebates or reductions have been introduced, British

Gas works in partnership with several UK local authorities to offer residents council tax rebates for

investing in home insulation12. This scheme may provide a useful opportunity to explore the

potential for such reductions to influence household behaviour.

Both the Phase 1 and 2 scoping reviews highlight the importance of undertaking public engagement

prior to rolling out any reward or recognition scheme, in order to understand which rewards (or

recognition) will be most salient to the target populations. Very few trials explained why they had

chosen the particular reward in question or how they expected it to motivate the target group, and

few indicate trying to understand the interests or needs of their target population prior to

implementing the trial. The rewards used in the Food Dudes healthier eating intervention (Horne et

al., 2004; Lowe at al., 2004) (evaluated in a peer-reviewed study, summarised in Annex 1) were

designed on the basis of prior research exploring children’s preferences and the types of rewards

they would likely respond to, with the ‘Food Dude’-branded stickers and stationery proving popular.

Although not formally evaluated, discussions with Merseyside TravelWise noted the effectiveness of

offering stickers to primary school children; identifying them as a simple but alluring reward for that

age group. For older children, there is some indication in the grey literature that leisure-related

rewards may be effective; for example, the free cinema tickets provided in the Merseyside ‘Big

Walk’, the cinema tickets and retail vouchers offered by the Step2Get scheme (Bird, not dated), and

those provided in the volunteering-related schemes, Orange RockCorps13 and Spice (University of

Wales, 2008) (see Annex 1 for brief descriptions of these initiatives). Such initiatives would benefit

from more rigorous evaluation to provide a more reliable indication of the potential for such

rewards to influence behaviour.

The findings from the focus group participants indicated a preference for choice in the rewards

offered. Each focus group, be it with new or existing recyclers, included a mix of participants who

felt more motivated by community-based rewards and those calling for better and more appealing

rewards for individuals. Many participants appreciated community or charity rewards for providing

an additional societal benefit of their recycling efforts (with a particular preference for smaller

charities and local causes), but most felt there should be options for both individual and community

rewards. With respect to individual rewards, participants indicated a general lack of interest in

rewards tied to minimum spends or those trying to encourage them to go to places they would not

normally visit. Participants called for a wider variety of reward options to choose from, including:

reductions in council tax bills (perhaps the most frequently volunteered suggestion across the

groups); rewards linked to transport, such as reduced fares or free passes; rewards linked to leisure

time, be it free gym passes and swimming sessions or days out for the family; or rewards linked to

improvements in local recycling service provision, for example being given a free green bin and food

waste collection.

With regard to feedback-based interventions, a number of robust conclusions can be identified from

within the peer-reviewed energy literature and, to a lesser extent, the non-peer reviewed water

conservation literature. Feedback appears to be most successful when:

(a) provided as soon as possible after undertaking the behaviour in question (Grønhøj and

Thøgersen, 2011);

(b) presented in a simple way, using meaningful units, and providing the option for

particularly interested individuals to find out more detail about the breakdown of energy

use by appliance or activity (Anderson and White, 2009; Faruqui et al., 2010; Hargreaves et

al., 2010);

(c) it acknowledges the way in which energy and water use is negotiated by the whole

family, rather than one household member (Darby, 2010a);

(d) combined with goal setting, be it group or individual goals (Abrahamse et al., 2005, 2007;

McCalley et al., 2011; Wood and Newborough, 2007);

20

(e) it includes a meaningful comparison of some kind, be it personal use during the same

time period the previous year (historical feedback) or the average use of a relevant

comparison group (socially comparative feedback) (Iyer et al., 2007);

(f) it combines both descriptive and injunctive norms, an approach which shows some

potential (though based on small sample sizes and short-term feedback trials) for

overcoming ‘boomerang’ effects14 amongst low-consuming households (Ayers et al., 2009;

Schultz, 2007); and

(g) combined with support and advice concerning how to respond to the feedback gained

(Harder and Woodard, 2007; Staats et al., 2004).

In contrast to the discussion about individual level feedback, the participants in the focus group did

not call for feedback in terms of waste diverted from landfill or increased recycling tonnage; they

wanted to know the positive community benefits of their actions15 (how many Golden Tickets had

the schools collected? What equipment had they bought?) or to see where their recycling goes,

what is it used to produce and what quantity of resources was saved by recycling rather than

producing products from new?

5.4 WHAT CONTEXT-SPECIFIC ISSUES HELP OR HINDER THE SUCCESS OF THE

SCHEMES?

It is difficult to identify the context-specific issues that contribute to scheme success because the

relative impact of different contributory factors is rarely evaluated. Nonetheless, a clear message

emerging from both reviews is that, for many individuals, rewards and feedback will be most

effective when complemented with additional measures that will support and enable the desired

behaviour changes over the long-term (a finding that is common to many behavioural interventions).

It should be noted that the level of additional support required will likely vary depending on the

nature of the behaviour in question; greater social support or skills development may be needed, for

example, to change behaviours constrained by significant psychological influences (such as the

addictive behaviours discussed in the health literature) than more simple behaviours such as

recycling.

The literature identified in the Phase 1 Review stresses that reward-based interventions need to be

underpinned by comprehensive recycling infrastructure and service provision (AEA Technology,

2006; Maunder et al., 2003) and accompanied by targeted communications, public engagement and

feedback (Iyer and Kashyao, 2007). Participants in all six focus groups emphasised the importance of

improved education (from school onwards), communications and outreach, and supporting

infrastructure to make it easier for them to recycle. In particular, a key constraint highlighted by

both new and existing recyclers was the disparity between materials that can technically be recycled

and those which the Local Council will actually collect. For existing recyclers, this leads to frustration

as they feel they cannot recycle all that they would like to, whilst for new recyclers, it leads to

confusion and anxiety about what can and cannot be recycled. Further frustrations concerned the

barriers to recycling, reuse and repair resulting from irresponsible industry practices, which was

mentioned by participants in all focus groups.

The ‘boomerang effect’ is a concern raised when comparative feedback interventions are used with households who are already demonstrating relatively low levels of energy consumption, and which may react to the feedback by increasing their consumption so as to reduce their deviation from the norm.

15 This mirrors a finding identified in the Phase 1 Review, in which Woollam et al. (2003) emphasise the importance of providing positive feedback of local achievements.

21

Similarly, the literature reviewed in the Phase 2 Review in relation to energy-use behaviours, notes

that existing behaviours suffer from two sources of inertia; the habitual routines and practices at the

level of the individual and the wider socio-technical systems that drive and reinforce these practices

(Marechal et al., 2010). Interventions, such as rewards or feedback, that only target the individual

will come across barriers unless they occur in the context of broader socio-technical transitions that

can sustain personal changes in energy-use patterns, ensuring they become part of the prevailing

social structure or social practices (Breukers et al., 2009).

5.5 WHAT ARE THE EFFECTS OF REWARDS ON PEOPLE WHO MAY ALREADY BE

ENGAGING IN THE DESIRED BEHAVIOUR?

Critics of reward schemes may cite Frey’s theory of ‘motivational crowding out’ (Frey and Jegen,

2001; Frey 2007); the risk that external rewards ‘crowd out’ (i.e. undermine) the intrinsic

motivations of those already engaging in the target behaviour. Very few studies within the literature

reviewed have sought explicitly to test this theory in a real world situation. One study (Carpenter

and Myers, 2010) notes that the provision of a small stipend reduced the motivation amongst a

small subset of volunteer firefighters to continue volunteering, but these were primarily those for

whom a key initial motivation for volunteering related to the desire for improved self image.

As discussed earlier, two meta-analyses (Cameron and Pierce, 1994; Deci et al, 1999) (primarily

synthesising lab-based and econometric crowding out studies) found evidence of crowding out only

when tangible, as opposed to verbal, rewards were promised prior to task completion, which was

found to be particularly detrimental amongst school children. The Food Dudes school-based

healthier eating trial offers useful insights here, with the authors (Horne, 2004; Lowe 2004) noting

that the context and method of reward delivery were critical to the scheme’s success over the long

term. The context in which the rewards were given in these trials was designed to avoid coercive or

negative associations; they focused on the intrinsic virtues and enjoyment of eating fruit and

vegetables, extolled by the Food Dudes, and rewards were presented as positive indicators of

children’s positive achievements. Teachers were asked to use the rewards as marks of achievement,

accompanying them with positive encouragement and praise, rather than as a bribe prior to eating

the fruit and vegetables provided. This perhaps reflects Frey’s (Frey and Jegen, 2001; Frey 2007)

theory of ‘crowding in’ whereby rewards seen as supportive, rather than controlling (i.e. used to

praise or recognise efforts made rather than as a bribe), may actually serve to ‘crowd in’ more

intrinsic motivation, and encourage further participation in the target behaviour.

The limited primary research undertaken for this project identified no crowding effects amongst the

existing recyclers engaged in the Recyclebank or Golden Ticket reward schemes, but due to the

sample including only participants, no clear conclusions can be drawn about those who were not

engaged by the scheme. For participating high recyclers, the self-reported behavioural impact of

rewards was limited, but no adverse impacts were identified, nor any indication of motivational

crowding out. High recyclers tended to see the rewards as ‘something for nothing’ and positive

recognition of their efforts.

The case studies suggest that competition-based models seem particularly attractive to those who

are already performing a desired behaviour but who could be doing more, as demonstrated by the

enthusiasm of participants in the Energy Neighbourhood competition (Intelligent Energy, not dated)

(summarised in Annex 1) and the various workplace Cycle Challenge schemes (TravelWise

MerseySide, 2009). Whilst none of these schemes have been evaluated or discussed in a peer

Page 25: Synthesis Report: Review of evidence on the use of reward ...psi.org.uk › pdf › 2015 › reward_and_recognition-SynthesisReport.pdf · developing, delivery or implementation of

22

reviewed source, scheme representatives suggest such individuals may be motivated more by the

challenge posed by the competition rather than the actual prize itself.

One negative outcome observed of providing comparative feedback to those already participating in

a desired behaviour is the ‘boomerang effect’, explored in two energy-related studies where norm-

based feedback was provided to influence household energy consumption (Schultz et al., 2007;

Ayers et al., 2009) and in a food waste recycling feedback intervention (Nomura at al., 2011). In the

context of energy conservation, the ‘boomerang effect’ refers to occasions where households who

are already demonstrating relatively lower than average levels of energy consumption react to the

provision of descriptive norm-based feedback by increasing their consumption. The two energy-

related studies sought to overcome this through combining the descriptive norm with an injunctive

norm (indicating approval of their current level of consumption with a positive emoticon). Whilst

Schultz et al. (2007) found this to reverse the effect (based on a small study sample and short-term

feedback trial), very minor boomerang effects persisted in the larger-scale study undertaken by

Ayres et al. (2009), suggesting this is an area where further research would be of value. No evidence

of this effect was found amongst participants discussing the impact of ‘smart communications’ on

household water use (Rathouse, forthcoming) but this was a small-scale study, which only explored

self-reported behaviours in a focus group context.

5.6 TO WHAT EXTENT IS THE IMPACT OF ANY REWARD SCHEME LIMITED OVER

TIME?

Concerns have been raised in the grey literature that incentivising recycling using financial rewards

runs the risk of establishing the recycling of waste, rather than its reduction, as the social norm

(Mitchell and Maunder, 2005), and that adverse effects on behaviour could occur over the long-

term, particularly if the rewards are withdrawn at a future date.

We found no long-term research in the Phase 1 Review on the longevity of changes to waste

prevention behaviour triggered by different types of reward or feedback schemes. While both

Recyclebank schemes in the UK appear to have resulted in increased recycling participation rates16,

neither have been running long enough to evaluate the longevity of these changes or the impact on

longer-term behaviour of removing the reward component of the schemes.

Similarly, despite the significant body of evidence on the use of rewards to influence health and

education behaviour and on the use of feedback to influence household energy conservation, very

few studies were identified that have undertaken the systematic, long-term monitoring required to

be able to draw reliable conclusions concerning the long-term impacts of rewards on behaviour (for

example, see Cahill and Perera, 2008). In one large-scale, longer-term study exploring the impact of

rewards on smoking abstinence (Volpp, 2009), 9.4% of the reward group remained smoke-free at

15/18 months, compared to just 3.6% of the control group. However, the degree to which these

findings can be generalised is limited since participants were all employees of a large American

company, were predominantly white, and enjoyed relatively high levels of education and income.

Furthermore, the psychological barriers to smoking cessation are likely to be significantly greater

than those preventing engagement in recycling and wider waste prevention activities.

16

As highlighted by a recent Recyclebank press release: http://www.Recyclebank.com/corporateinfo/index/pressreleasearticle/id/164

23

Many of the initiatives discussed in the review have been in place for a while and reportedly

continue to attract new participants, such as the Bike Miles scheme17, Personal Travel Planning

programmes (DfT, 2005, 2008a, 2008b; Williamson, forthcoming), the EcoTeams initiative (Hargraves

et al., 2008; Staats et al., 2004) and community currencies (Seyfang, 2003, 2004b, 2006a, 2006b,

2009b). However, in all of these initiatives, the rewards and/or feedback constitute just one

component in a much wider package of measures, and whilst the rewards/feedback are considered

to be an important part of the intervention, the literature suggests they are rarely sufficient to drive

longer-lasting change (though not all of this literature was peer-reviewed).

One point to note from studies that have used electronic feedback to influence household energy

behaviours is the ‘draw of the gadget’ (Grønhøj and Thøgersen, 2011). Changes in behaviour that

stem primarily from curiosity of new technology, such as smart meters, appeared to wear off over

time. Households’ use of the electronic feedback appeared to change with prolonged exposure;

shifting from a detailed inspection of the consumption of individual devices in the beginning to

undertaking a periodic scan to check nothing ‘unusual’ was happening at later stages.

5.7 IS THERE ANY EVIDENCE OF INCREASING CONSUMPTION TRENDS AS A

RESULT OF THE GREATER PURCHASING POWER PROVIDED BY REWARDS?

None of the studies reviewed explicitly explored the impact of rewards on the consumption patterns

of participating individuals, though the concern was raised within two Phase 1 grey literature

sources (London Assembly, 2001a, b).

One initiative to note in relation to this is the NU Spaarpas initiative piloted in the city of Rotterdam

in the Netherlands (Seyfang, 2006a, b) (summarised in Annex 1). This scheme rewarded city

residents for specific pro-environmental behaviours (e.g. separating their waste for recycling, using

public transport, shopping locally or purchasing ‘ethical’ products) with ‘green points’. These points

could be redeemed locally, but only for public transport tickets or discounts on sustainable products,

or they could be donated to charity. Although it is not clear from the source whether this design was

explicitly adopted to minimise the risk of increasing consumption trends, there may be value in

learning more about the successes (or otherwise) of this initiative, particularly given the recent

launch of the London Green Points scheme in Bexley18. This scheme will be rewarding residents for

recycling, reuse and waste reduction with green points, which may be redeemed for a range of eco-

products, days out or donated to selected local charity projects.

5.8 IS THERE ANY EVIDENCE THAT REWARDS TARGETING ONE TYPE OF

BEHAVIOUR CAN LEAD TO GREATER PARTICIPATION IN ANOTHER?

Very few studies identified in either review explicitly examined or reported the existence of spillover

effects (the idea that an intervention targeting one behaviour also leads to changes in another,

usually, linked behaviour) as a result of reward or feedback-based interventions. Hargreaves et al.

(2010) undertook a series of semi-structured interviews with participants who had been trialling

three different types of smart energy monitors in a ‘Visible Energy Trial’. A range of spillover

behaviours was observed amongst a small number of participants - including cutting consumption in

other lifestyle areas (often transport-related) or making efforts to encourage others to reduce

24

consumption as a means for reducing their expenditure. However, it should be noted that these

participants had already expressed strong pro-environmental values prior to the trial.

A different type of ‘spillover’ was highlighted in an evaluation of the British Gas Green Streets

competition (IPPR, 2011), in which 14 groups from varied communities across England, Scotland and

Wales were selected to compete for a prize of £100,000 (see Annex 1 for a summary of the

competition). Each community was given a share of £2 million investment of capital, together with

technical advice and support from British Gas, to spend on a range of microgeneration and energy

efficiency measures in community buildings and surrounding households in the pursuit of three core

objectives: saving energy, generating energy and engaging the ‘wider community’. An unexpected

benefit of the competition was identified within the responses to a post-competition survey of

approximately 1300 non-participants in households within a distance of, on average, 1.25km of

community buildings that participated in the projects. The survey analysis highlighted the potential

for such a challenge to catalyse wider community engagement in energy issues: (a) 30% respondents

said that, though not directly involved, being aware of a Green Streets project had changed their

attitudes towards energy efficiency and renewable energy; (b) 46% respondents had been inspired

to take action on energy efficiency and renewable energy, such as installing insulation (50%),

installing a new boiler (23%), installing solar PV panels (11%) and undertaking smaller actions such as

installing energy efficiency light bulbs and switching off plugs; and, (c) 61% said they would be more

likely to take action in the future. Whilst the risk of social desirability bias should be acknowledged,

this does point to the potential ‘spillover’ of the desired behaviour from the target populations to

non-participating households nearby. This could usefully be explored further in future waste-related

community competitions.

5.9 A TYPOLOGY OF REWARD AND RECOGNITION SCHEMES

One specific aim of the Phase 1 Review and Case Study Analysis was to propose a typology for the

different types of reward and recognition schemes that are in operation, or have operated, within

the context of waste and recycling.

In doing so, an obvious starting point was the distinction that emerged from the literature between

schemes which monitor and reward individual behaviour and those which are collective in focus.

However, this distinction is muddied by the fact that reward and recognition schemes have two

components ‒ the monitoring of behaviour and the subsequent reward or recognition of that

behaviour ‒ and that each of these components may be individual or community-based. So, some

schemes may monitor the behaviour of a community but reward or feedback to individuals, while

others may monitor the behaviour of individuals but provide community-based rewards. This leaves

four possible ways in which a scheme might operate19:

One-to-one: a scheme that monitors individual behaviour and rewards individuals

One-to-many: a scheme that monitors individual behaviour but rewards a community

Many-to-one: a scheme that monitors community behaviour but rewards individuals

Many-to-many: a scheme that monitors community behaviour and rewards communities.

19

Note that ‘rewards’ here is used to mean rewards and recognition, which may include just feedback.

Page 28: Synthesis Report: Review of evidence on the use of reward ...psi.org.uk › pdf › 2015 › reward_and_recognition-SynthesisReport.pdf · developing, delivery or implementation of

25

Note that the term ‘community’ does not necessarily imply a geographical community or

neighbourhood; in the case of Manchester’s Golden Ticket scheme (Case Study 4), the community

rewards are offered to a local primary school.

While this distinction is useful, it is not always possible to classify a scheme discretely because some

schemes are flexible or implemented differently in different areas. For example, the kerbside

Recyclebank schemes included in Case Study 5 have different models that monitor both individual

and collective behaviour. Similarly, while participants in the Recyclebank scheme can choose to

spend their vouchers in shops or other local leisure facilities, they can also donate their points to

local schools at certain times during the year. An overriding message from the focus group

participants is the need for schemes which present options for both individual and community

rewards.

As well as distinguishing between schemes according to the way in which participation is monitored

and rewarded, a second useful distinction is between monetary and non-monetary schemes. As

above, schemes do not necessarily fall into one of these two categories neatly. While cash rewards

or cash back schemes lie squarely at the monetary end of this spectrum, a number of other schemes

offer vouchers or non-monetary gifts as a reward. For example, reverse vending machines like those

found in the car parks of supermarket Tesco, reward people for recycling with Tesco Clubcard points.

At the other end of this spectrum, are schemes which offer gifts (such as the temporary Teignbridge

organic box scheme trialled in the Defra Household Waste Incentive Pilot Scheme) or provide purely

verbal or written feedback on performance.

Figure 2, below, illustrates how different schemes map according to both the way in which

monitoring and rewards are offered, and the types of reward.20 Note that Recyclebank (Case Study

5) crosses the boundary between both ‘one-to-one’ and ‘one-to-many’ because of the different ways

in which the scheme can be structured, and the different types of incentives which it offers to

participants.

20

More information about the different schemes featured can be found in Annex 1 to this report and the separate Technical Annex.

Figure 2: Mapping reward and recognition schemes according to scheme and incentive type (5 case studies

in darker shading)

In our initial proposal, we suggested devising a detailed typology based on incentive types, collection

design, scheme providers, and community context. However, we have not been able to gather

enough information about existing reward and recognition schemes to do this. In part, this is

because it is difficult to obtain reliable and detailed information about past schemes and trials that

are no longer in operation. Contacting local authorities to try and obtain information has proven a

time-consuming and largely fruitless task. In addition, there are still relatively few waste-related

reward and recognition schemes currently in operation. While we would not claim that the list in

Annex 3 in the Technical Annex is comprehensive, there do not appear to be enough schemes

currently in operation for the development of a more detailed typology.

6. OPPORTUNITIES FOR FUTURE RESEARCH

In this section, we present a range of research opportunities for researchers, practitioners and

policy-makers engaged in current or future reward and recognition schemes or trials. These are

based on the evidence gaps identified within both Scoping Reviews and the case studies, and the

issues raised during the focus groups.

Isolating the impact of rewards or recognition

The Phase 1 Review and, more specifically the case studies, noted the lack of robust evidence that

successfully isolates the specific impact of rewards or feedback on recycling and waste prevention

behaviour from the confounding impacts of wider accompanying activities such as communications,

infrastructure improvements, or extended producer responsibility (Meneses and Palacio, 2004;

Dahlén and Lagerkvist, 2009; Timlett and Williams, 2008). Are other components of the scheme

more important that the rewards themselves? Schultz (1999) suggests value in trying to generate

effect sizes (i.e. identifying the size of the impact) for different types of interventions in different

contexts.

Similarly, the Phase 2 Review noted the need to gain a better understanding of the mechanisms by

which reward schemes work; why are rewards, such as vouchers or points, found to be an effective

mechanism for encouraging initial changes in behaviour if they are not then redeemed? One

possible reason for this, which could usefully be explored further in future schemes, is highlighted by

the focus group findings. In the Maidenhead focus groups, participants highlighted their

appreciation of the Council’s decision to introduce a reward scheme for households at a time when

other councils in the country were introducing fines; ‘that made me feel sort of warm towards the

whole thing and that’s why I got actively involved in it’ [existing recycler, Maidenhead]. Whilst many

of these participants were yet to redeem any rewards, it seems the reward scheme changed the

nature of relationship between the focus group participants and the Council, such that they were

more predisposed to engage in the scheme.

In light of these remaining evidence gaps and uncertainties, future reward and recognition schemes

and/or trials would benefit from rigorous evaluation approaches21, using randomised or matched

control groups, in an effort to estimate the counterfactual and determine the importance of the

rewards themselves and the influence of rewards in isolation from confounding factors.

Understanding the differential effects of rewards on recycling compared to wider

waste prevention activities

There is a clear lack of empirical testing of the impact of rewards or recognition on reuse, repair or

reduce behaviours. With the exception of a handful of schemes (such as those that promote the use

of real nappies and the reuse of plastic carrier bags), much of the focus of waste-related reward and

recognition schemes to-date has been on recycling initiatives.

The health and energy literature reviewed in Phase 2 suggested that rewards are most effective in

influencing simple, infrequent behaviours, or in encouraging initial engagement in more complex,

habitual behaviours, with additional support needed to sustain engagement. Whilst the

21

28

psychological barriers to changing health behaviours may be significantly greater than those

inhibiting participation in recycling or wider waste prevention activities (particularly where an

addiction is involved), future reward and recognition trials or schemes could usefully explore the

differential effect of rewards and/or feedback on one-off versus more routine waste-related

behaviours. For example, efforts could be made to evaluate the influence of rewards and/or

feedback on more infrequent repair and reuse decisions in comparison to routine, habitual recycling

activities to see if the simple-complex behavioural distinction is also true for recycling and waste

prevention behaviours.

Understanding which rewards are the most salient for different target groups

Are particular types of rewards more or less appealing to different groups? For example, drawing on

the Phase 2 findings, do low income groups prefer cash-based rewards? Do teenagers prefer leisure-

related rewards? Do stickers always work for primary school children? What constitutes a

meaningful comparison group for households receiving socially comparative feedback? Does the

value of the reward matter? Is there a certain threshold in reward value at which different groups

are more likely to respond? Are certain groups more likely to respond to rewards than others? Both

the Phase 1 and Phase 2 Reviews suggest the greatest changes may be observed when rewards

and/or feedback are targeted on ‘average’ (rather than low) performers who express an interest or

willingness to do more if given the support to do so. This hypothesis could usefully be tested in

future reward and recognition trials.

The London Assembly (2011a) ‘Carrots and Sticks’ inquiry report highlights the need for a better

grasp of the impact of rewards and feedback targeted at different groups, for example on low/non-

recyclers versus medium or high recyclers (Allen et al., 1993), those living in high rise flats versus

those in mid-rise flats; and rural versus urban areas. Brook Lyndhurst (2009) also emphasise the

need for more specialised research on minority ethnic groups that acknowledges and explores the

diversity of experience both within and between groups. This mirrors the call in Bennett et al. (2008)

for more research into the recycling habits of individuals within specific ethnic and socio-

demographic groups, particularly within socially deprived localities. Bennett et al. also suggest

further research is needed into the value of different types of reward scheme for encouraging waste

prevention amongst more transient populations.

All of these queries reiterate the need to undertake more extensive public engagement prior to

rolling out any future reward and recognition schemes, to understand which rewards will be most

salient to the target populations and what additional support they may need alongside the rewards.

Public awareness of waste disposal and recycling costs

The appeal of rewarding household recycling and waste prevention efforts with council tax rebates

was mentioned both within the literature (Brook Lyndhurst, 2009; Maunder et al., 2003) and

amongst the focus group participants. There was a clear sense amongst the focus group participants

that if they were doing more to help the Council by recycling more, this should be reflected in their

bills. At the same time, there were calls for a more comprehensive kerbside recycling service, in

which more materials are collected; if a product label indicates that the packaging is recyclable,

participants felt it should also be accepted by the kerbside recycling service (especially in relation to

plastics). Therefore, whilst individuals want to see their Council tax reduced, they also want an

Page 32: Synthesis Report: Review of evidence on the use of reward ...psi.org.uk › pdf › 2015 › reward_and_recognition-SynthesisReport.pdf · developing, delivery or implementation of

29

increase in the scope of materials collected by (and therefore the costs of providing) the kerbside

recycling service.

Future research could usefully explore this tension further, together with the extent to which council

tax rebates continue to appeal when participants realise the (low) proportion of council tax

payments actually spent on waste disposal and recycling.

Framing of the reward

How can rewards be awarded or presented in a way that acknowledges achievements without

creating an expectation of additional rewards in response to sustained behavioural changes or

additional achievements in the future? Should they be contingent on attaining specific behavioural

outcomes or given solely for engaging in a particular programme of behavioural change? One meta-

analysis (Cameron and Pierce (1994) of largely laboratory-based and econometric crowding out

studies concluded that tangible rewards produced no effect when delivered unexpectedly, and were

not detrimental when expected and contingent on level of performance or completing or solving a

set task. However, no studies were identified in either review that have explored this in a real world

setting, and this could therefore be addressed in future reward or recognition trials.

Measuring performance

A number of focus group participants noted the importance of fairness when designing schemes.

There was a sense that weight-based measures are flawed since they effectively penalise individuals

who are making waste reduction decisions at the point of purchase (and therefore reducing both

their residual waste and recycling generation) and smaller households who will likely generate

recycling. Participants also felt that there is no way of checking that people are actually filling their

bins with materials that can be recycled, rather than non-recyclable but heavy items. Similarly,

participants in the Lambeth scheme were suspicious that people could cheat the self-report system

and called for rewards to be based on actual performance. At the same time, a finding of the Phase 1

review was a lack of conclusive evidence concerning the likely impact and cost-effectiveness of

reward or feedback schemes based on contamination rates rather than weight. This suggests a need

for future schemes to trial the effectiveness and cost effectiveness of rewarding participants for

recycling the correct items and/or for reducing waste, rather than relying solely on weight-based or

self-report systems.

Are rewards needed or is recognition and reassurance sufficient?

Whilst both reviews identified studies that have explored the behavioural impact of providing

feedback to study participants, very few studies were identified that evaluated the impact of

tangible rewards in comparison to the impact of feedback. Do all individuals need a tangible reward,

or is verbal/written recognition sufficient? What is the potential for introducing award-based

schemes where rewards deliver reputational – rather than tangible monetary or gift-based –

benefits?

Linked to this, many of the focus group participants called for greater feedback, not in terms of their

personal recycling performance (waste diverted from landfill, increased recycling tonnage), but

rather in terms of: (a) the tangible community benefits gained as a result of their recycling efforts

(e.g. in the case of the Golden Ticket scheme, how many Golden Tickets had the schools collected?

Page 33: Synthesis Report: Review of evidence on the use of reward ...psi.org.uk › pdf › 2015 › reward_and_recognition-SynthesisReport.pdf · developing, delivery or implementation of

30

What equipment had they bought for the children?); and (b) reassurance that their recycling efforts

are worthwhile (e.g. where did their recycling go? What has it been used to produce and what

quantity of resources was saved by recycling rather than producing products from new?). Future

trials could usefully evaluate the behavioural impact of providing this type of reassurance and

recognition alongside rewards in comparison to the impact of providing reassurance and recognition

alone.

How can reward schemes be designed to encourage spillover?

Very little evidence was identified in either review that explored the potential for rewards or

recognition to influence behaviours beyond the primary target behaviour. The Phase 2 Review

suggested that competition-based schemes tend to attract those who are more ‘ecologically

conscious’ and it is these individuals who are more likely to demonstrate spillover behaviours.

Further research could explore the potential to use competition-based models to encourage

spillover behaviours amongst medium or high recyclers; for example how could future recycling

reward or recognition schemes be designed in a way that also encourages greater reuse or waste

reduction behaviours, or even wider pro-environmental behaviours? In the focus groups, a reward

considered to be appealing by some individuals was the idea of rewarding recycling with tickets for

free public transport, which may potentially also encourage a shift towards more sustainable

transport behaviours. The London Green Points scheme, recently launched in Bexley, may provide

valuable insights in this regard.

Do reward schemes promote consumption?

A concern that is commonly raised in response to proposals to introduce reward schemes is that

tangible monetary rewards could serve to increase consumption and thereby enhance waste

generation. This concern was mentioned within grey literature sources included in the Phase 1

Review but neither review found any empirical evidence to support it. Furthermore, whilst the

findings cannot be generalised to the wider population, a number of focus groups participants

reported ignoring rewards which require a minimum spend or buy-one-get-one free options, both of

which would otherwise increase consumption. Much more research is needed to explore whether

reward-based schemes promote increased consumption, and if so, how could such schemes be

designed to avoid such increases? This should be considered in any future scheme in which tangible

monetary-based rewards are provided.

Longevity of behaviour change

Our Phase 1 Review found no long-term research on the longevity of waste-related behaviour

change triggered by different types of reward or feedback scheme (Lyas et al., 2004), and very few

sources explored this in the Phase 2 Review (the issue was only considered in the health incentives

and energy feedback literature, but few studies had systematically explored such effects). As Hornik

et al. (1995) point out, there is a need to understand which interventions promote intrinsic as well as

extrinsic motivations to engage in waste prevention behaviours, and the implications of this for

inducing long-term waste prevention behaviours. Linked to this is the need to identify how best to

maintain increases in recycling participation over time following implementation of a reward. Is it

better to reincentivise or to communicate with and educate residents continually to maintain their

interest in preventing waste? (London Assembly, 2001a). The ongoing Recyclebank scheme could

provide a useful starting point for exploring this further.

Page 34: Synthesis Report: Review of evidence on the use of reward ...psi.org.uk › pdf › 2015 › reward_and_recognition-SynthesisReport.pdf · developing, delivery or implementation of

31

The evaluation budget of future reward and recognition trials should include an allocation towards

longer-term monitoring, allowing the evaluator to conduct annual evaluations whilst the scheme is

still running and, should the rewards be withdrawn at any stage, to return to participants at least

one year after their removal to see if any changes in behaviour triggered by the rewards have been

sustained.

Targeting moments of change

Though not a focus of this work, one area for further research is the potential to target rewards on

individuals undergoing transitions and moments of change, for example new residents in an area

who have not yet established their routines and habitual behaviours? Bamberg (2006) observed a

significantly greater increase in public transport use amongst new residents who received a free bus

pass and public transport schedule information upon arrival in their new home than amongst new

residents without this intervention. The potential for taking advantage of such windows of

opportunity could usefully be explored in future reward and recognition trials, particularly given the

Phase 1 Review finding that areas with highly transient populations are often harder to engage in

recycling initiatives.

CONCLUDING COMMENTS

This project has sought to bring together existing evidence on the potential for rewards and

recognition to influence behaviour, both in relation to recycling and waste prevention behaviours (in

the Phase 1 Review) and to seven non-waste behaviours (in the Phase 2 Review). The findings

identified in the two scoping reviews were built on and complemented by those of the focus groups.

It is clear that, whilst a number of reward and recognition trials and schemes have been introduced

to influence behaviour, a number of evidence gaps remain. Defra’s recently commissioned Reward

and Recognition pilots offer a valuable opportunity to begin to address these gaps in the context of

recycling and waste prevention behaviours. Perhaps the most pertinent gaps to consider include:

the need for more rigorous and long-term approaches to evaluation in order to

understand the specific mechanisms by which rewards and recognition work, and their

influence on different target groups;

the cost effectiveness of reward and recognition/feedback schemes;

the influence of rewards on consumption i.e. potential rebound effects; and

the long-term effects of rewards and recognition on behaviour (including the target

behaviour and other linked behaviours), and an understanding of the additional measures

needed to support and sustain behaviour change beyond the initial introduction of the

rewards or recognition.

8. ANNEX 1. REWARD AND RECOGNITION SCHEME DETAILS

This annex provides a brief description of the Case Studies and other reward schemes referred to

within this Synthesis Report. Further details are provided in the accompanying technical project

reports and Technical Annex.

Case Study 1. Recycling Reward Scheme, Ealing:

A community competition, run between wards in Ealing from November 2010 to May 2011, in which prizes of £20,000 were awarded to the local wards with the highest, and those with the most improved, rates of recycling. Awards were based on participation monitoring rather than the weight of recycling collected. The prize money has been awarded to local ward forums which any resident can attend, which means local people can have a say in how the prize money is spent.

Case Study 2. Trial providing feedback on food waste recycling, Oldham:

A randomised control trial to explore the impact of street-based feedback on household participation in food waste recycling. The eight-week trial was conducted during the autumn of 2009, with 9082 households (5009 in the control group and 4073 in the treatment group). Though only a short-term trial, the feedback provided had a modest positive impact on household food waste recycling participation rates, with an effect size of 2.8%.

Case Study 3. Marks and Spencer/Oxfam Clothes Exchange:

An individual reward scheme, which awards individuals with Marks and Spencer vouchers for recycling unwanted clothes through Oxfam. Customers who include at least one item of Marks and Spencer clothing in their donations to Oxfam may request a Marks and Spencer voucher worth £5 to use against their next purchase of over £35 worth of clothing, homeware or beauty products at Marks and Spencer. The scheme sought to increase donor loyalty to Oxfam at a time of rising demand for ‘rag’ and corresponding increases in bogus textile collections.

Case Study 4. Golden Ticket recycling scheme, Wythenshaw:

A community-based reward scheme, run in the Sharston Ward, Wythenshaw, from January to May 2011, in order to encourage greater household participation in dry recycling. Each time householders put their recycling bin out for collection with the correct materials inside, a ‘Golden Ticket’ was attached to the bin’s handle. These tickets were collected by two participating local schools which could exchange the tickets for money to buy teaching equipment (such as books, new technology or sporting equipment) or to be spent directly within the school.

Case Study 5a. Recyclebank, RBWM:

An individual reward scheme introduced to the RBWM in June 2010. Points are awarded to participants on the basis of the weight of dry recyclables placed in new individual (or for flats, communal) blue wheelie bins, which are embedded with a Radio Frequency Identification Device (RFID). This chip enables individual bins to be linked to households (or groups of households for communal schemes) using encrypted coding. Waste collection vehicles are fitted with scanners and scales, allowing them to capture the weight of the materials collected. This data is then sent to a central database. Participants claim rewards at participating retail and entertainment outlets, based on the number of points they collect.

Case Study 5b. ‘I Recycled’, Recyclebank Lambeth:

A variant on the RBWM Recyclebank scheme, introduced specifically to estate residents in Lambeth in May 2011. The ‘I Recycled’ scheme relies on self-reporting by participants, be it online (logging in to click ‘I recycled’), by phone or using a smart phone app. For every week that participants report having recycled, they receive 10 points, and additional rewards are shared equally at the end of each month based on the total weight of all recycling collected across the Borough.

Let’s Get Moving, Merseyside; (Lucas, forthcoming)

This scheme, funded by the European Social Fund, has been running since 2008, with the aim of promoting social inclusion in Merseyside by overcoming transport barriers and ensuring transport affordability for those who are transitioning from welfare into work. The scheme includes a wide range of initiatives, including: the provision of free face-to-face travel information, tailored advice, and guidance in an accessible format for those with disabilities or learning difficulties, and in other languages where necessary; personal journey plans; regular travel surgeries; attendance at job fairs and job cafes; feedback to Merseyside authorities on issues such as transport gaps, service demands, information needs; and travel passes, enabling up to one month’s free travel to work using public transport in the first month of employment, which is designed to cover the cost of travelling to work in the period between coming off benefits and receiving the first month’s pay. In addition, where public transport is not available, the scheme offers a low-cost loan of a motor scooter, ‘Scooter Commuter’, and all its associated set-up costs (including training and insurance) or a free bicycle, ‘Wheels to Work’. In a recent qualitative evaluation of the scheme (Lucas, forthcoming), there was unanimous agreement amongst participants that their biggest barrier to job uptake was finding the money to pay for travelling to work in the first month of employment; most of the clients who were in receipt of the free travel pass retained their employment status for at least 3-6 months [figures were not available regarding the average employment retention prior to the scheme].

TravelWise’s Big Walk, Merseyside; (personal correspondence)

A school-based scheme, run by the Merseyside TravelWise team, which aims to increase the number of children walking to school through biannual ‘Walk to School’ weeks. Each day a child walks to school in those weeks, they receive a sticker as a reward. Building on the success of this, an initiative called ‘The Big Walk’ was run throughout the summer term last year in partnership with the Liverpool Picturehouse cinema. Again, each day a child walked to school they received a sticker, but it was also recorded as a point in a class log book. Every pupil within the class that logged the most walking points at the end of the six-week period was given a free Picturehouse cinema ticket. Whilst evaluation data is not yet available, the TravelWise team highlighted school children as being particularly receptive to rewards, often more so than any of the other groups that had been targeted by travel-based reward schemes in the Merseyside area.

Step2Get, piloted in Bexleyheath (with 290 male students) and Wimbledon (with 299 female students); Bird (no date)

A walk to school scheme, created by the Smarter Travel Unit at Transport for London and Intelligent Health Ltd, offering rewards to secondary school children who walk to school. Each participant is given a personal radio frequency identity (RFID) card which they swipe at touch points (a series of battery operated receivers containing NFC mobile technology) along a designated walking route. The data is sent via mobile phone technology to a central database. When a participant has completed a designated number of walks, they can redeem a reward, choosing either cinema tickets (Odeon) or shop vouchers (TopShop). Participants can log on to a website to monitor their progress; viewing the number of days they have walked the route and how many more walks are required before earning a reward.

Bird (no date) has published an evaluation of two pilot Step2Get schemes online; as a result of the scheme, the modal shift from bus use to walking is in the region of 18% of the target market (the student population of a school taking part in a Step2Get scheme). The Bexleyheath pilot recorded an 18% reduction in the number of students boarding buses. In the Wimbledon pilot, the number of bus pick-ups at peak time fell by 57% as a result of the scheme, and 45% participants said they would switch to walking from other means of transport. In addition, wider benefits of the scheme included: improved student cohesion; improved road safety; increased levels of healthy, active travel; reduced

stress for bus drivers; reduced traffic and bus congestion; and, a reduction in the number of students arriving late to school each day (in the Wimbledon pilot), which could be enhanced by programming the system to discount swipes outside of set times or by providing free breakfasts for those who arrive earlier. The evidence of sustained behaviour change post-scheme is mixed and it is noted that extending the duration of the scheme would require improvements in cost-effectiveness.

Bike Miles, GlaxoSmithKline (GSK), Brentwood; personal correspondence

Introduced to employees in 2003 when the GSK headquarters moved to a new-build site where parking availability was limited. The Bike Miles reward scheme offers £1 per day to employees who choose to cycle to work (regardless of the distance cycled). Each employee registered on the scheme is given a sticker book, to which a sticker is added by the onsite security guard each time they cycle in. As stickers are collected they can be exchanged for vouchers, which may be redeemed at local bike stores. After filling the first £260 book, equivalent to a year’s cycling, cyclists progress to a gold and then platinum book, which comes with a special card bringing added benefits. The arrival of an onsite Evans bike store in 2007 resulted in a significant increase in the level of participation in the scheme (according to personal correspondence, a 3% increase in the number of participating employees was observed within the first year of the store opening). The store began administering the Bike Miles, and also provides onsite cycling retail, advice, bike maintenance and general support.

Whilst an evaluation of the Bike Miles scheme was not available, the scheme coordinator noted the importance of: putting the necessary supporting infrastructure in place alongside any reward scheme to ensure supported and sustained change (e.g. showers, secure bike racks, lockers, maintenance support); recognising that different people will require different types and levels of support to achieve a modal shift (for example, employees with dependents are much less likely to engage in the scheme due to other commitments, such as dropping off children at school en route to work); ensuring there is at least one dedicated person responsible for considering, enabling and encouraging sustainable travel modes in the workplace; and partnering with organisations who champion the different sustainable modes (e.g. Evans and, in relation to GSK’s walking promotions, Living Streets). GSK estimates the scheme to cost approximately £400 per cyclist per year.

Energy Neighbourhoods, multiple locations across Europe; Intelligent Energy, no date

A six-month community-based competition that ran from November 2008, with the aim of raising awareness of how behavioural changes can be used to save energy around the home. Originally developed in Belgium, the initiative spread to eight other European countries, including Bulgaria, France, Germany, Ireland, Italy, Spain, Sweden and the UK. An ‘Energy Neighbourhood’ consists of 8 to 10 households who form a team and compete with other ‘neighbourhoods’, all of which accept a ‘bet’ offered by the city council; that they could make energy savings of at least 8% over a six-month period, compared to the same period the previous year. Each team is coached by an ‘Energy Master’ who pulls the team together and provides ongoing support and advice. The municipality plays the role of referee and supporter, informing their citizens on how to save energy, organising get-togethers and ensuring the teams abide by the rules. Based on the results over the six-month period, an evaluation of the energy savings made was undertaken, and prizes given to the neighbourhoods that saved 8% of energy or more, awarded at one of a series of Regional Award Ceremonies. These national-level prizes consisted largely of energy saving packages, such as fleece blankets, light bulbs, solar games, and vouchers for organic stores. The special prize was a trip to the International Award Ceremony in Brussels, where each of the three households with the greatest national energy savings were awarded.

According to the project evaluation (Intelligent Energy, no date), around 60% of all participants managed to reach the target 8% energy saving and 80% of participating neighbourhoods saved energy in comparison to the previous year. All participants together achieved an energy saving of 11%, with the energy saved compared to the previous year amounting to 3320 tons of carbon

dioxide and 9,149,756kWh. However, it should be noted that the competition primarily attracted those who were already socially or environmentally engaged in their communities in some way.

Dormitory Energy Competition, US; Petersen et al., 2007

Petersen et al. (2007) report on a two-week campus-wide ‘Dormitory Energy Competition’ organised for students in March 2005. The aim of the competition was to encourage students to reduce both water and energy consumption within their dormitories. The study tested three types of feedback: (a) feedback received once per week on the aggregate electricity and water consumption of an entire dormitory (termed ‘low resolution’); (b) real time feedback on the aggregate use of an entire dormitory (‘high resolution’); and (c) real time feedback on the electricity use by students on individual floors within a dormitory (also ‘high resolution’). Feedback was socially comparative in the sense that each dormitory could see how other dormitories were doing during the competition through a competition website. The competition was intended to provide an incentive for conservation, and a context for advertising, educating and delivering the feedback on resource use within college dormitories. The feedback, education and the competition together resulted in a 32% reduction in electricity use, but only a 3% reduction in water use (perhaps due to the lower resolution22 of water feedback available and the limited emphasis placed on water use within the competition and accompanying materials).

British Gas Green Streets, multiple UK locations; ippr, 2009, 2011

14 groups from varied communities across England, Scotland and Wales were selected to compete for a prize of £100,000. Each community was given a share of a £2 million investment of capital, together with technical advice and support from British Gas, to spend on a range of microgeneration and energy efficiency measures in community buildings and surrounding households in the pursuit of three core objectives: saving energy, generating energy and engaging the ‘wider community’. The challenge ran from January 2010 until March 2011 and has since been evaluated by the Institute for Public Policy Research (ippr, 2011). This competition, Green Streets 2, built on the success of an earlier competition, Green Streets 1, which took place in 2009. Both Green Streets 1 and 2 have resulted in significant increases in energy savings, which are primarily attributed to the technology installations but also to the high levels of community engagement stimulated by the competition.

The EcoTeam Initiative, multiple locations across Europe; Hargreaves et al., 2008, Staats et al., 2004

Studies of this initiative, in which participating groups receive a combination of goal setting, information, support and group feedback, have identified significant changes in energy (and wider pro-environmental) behaviours (discussed by Staats et al., 2004; Hargreaves et al., 2008). An EcoTeam consists of 6-10 people who are recruited from the same neighbourhood and meets once a month (for approximately four to eight months). Each meeting is focused on a different household pro-environmental behaviour, for example waste prevention, gas, electricity, water, transport, and consumer behaviour. During the meetings the group, assisted by a facilitator, discusses the local and global issues relating to the behaviour in question, together with their personal experiences. Using information provided in the EcoTeam workbook and video, the group decides which practical changes they could make at home as well as the limits to what could be achieved. Between meetings, the EcoTeam members try out these changes at home, take regular measurements to monitor the impacts of these changes, ready to discuss their experiences and progress made at the next meeting. The results of the EcoTeam, in terms of reductions of waste and savings of gas, electricity and water are recorded in the EcoTeam log book, and results sent to a central database at the Global Action Plan office. The results of all active EcoTeams are compiled and used to give individual teams feedback about the amount of savings realised. During and after their active period,

EcoTeam members also receive feedback about the cumulative results of all EcoTeams operating during the same period by means of the EcoTeam newsletter, distributed every three months.

Staats et al.’s (2004) three-year longitudinal study of the Dutch EcoTeam programme found that eco-team participants (N=150) changed half of 38 household behaviours examined (based on both self reported behaviour change and physical measures of solid waste disposal, natural gas, electricity and water consumption). These improvements were sustained or increased two years after completion of the programme, resulting in savings of 6.7% on water consumption, 7.6% in electricity consumption, 16.9% in natural gas consumption, and 32.1% on solid waste deposition. Similarly, Hargreaves et al. (2008) present quantitative evidence of the effectiveness of the UK Eco-Team initiative in reducing waste and electricity consumption, drawing on the data collected by 58 Eco-Teams over a six-year period. This data suggests the programme has catalysed an average reduction in participating households’ electricity consumption of 6.86%, average increases in recycling of 7.71%, and average reductions in municipal solid waste of 19.66%. Early qualitative research suggests the EcoTeams programme encourages participants to minimise their waste by, for example, refusing packaging when shopping.

It should be noted, however, that many participants were already pro-environmental and undertaking activities at home prior to joining the scheme, particularly in the Dutch scheme, which raises questions concerning the potential of this group-based pro-active approach to encourage behavioural shifts amongst less environmentally-engaged households.

Food Dudes, trialled in multiple locations around the UK; Horne et al., 2004, Lowe et al., 2004

This scheme, a reward-based intervention for younger age groups (4-11), deploys a combination of taste exposure to fruit and vegetables at snack and lunch times during school hours, role modelling in the form of video adventures and letters from heroic peers, the ‘Food Dudes’, and rewards given to children according to the volume they eat of the fruit and vegetable portions given to them (Lowe et al, 2004; Horne et al, 2004). Following a baseline period where children are just given the free fruit and vegetable portions, the intervention was rolled out; over 16 days, children watched video adventures in which the ‘Food Dudes’ battle against the evil ‘Junk Punks’ who plan to take over the world by depriving people of their life-giving fruit and vegetables. To help them in their battle, the Food Dudes eat (and, importantly, are seen to enjoy), a variety of fruit and vegetables. Throughout the videos and through ‘letters’ read to the children by their class teacher, the Food Dudes urge the children to ‘keep the life force strong’ by doing the same. Throughout the 16-day period, children who eat their fruit and vegetable portions are given rewards, ranging from Food Dude stickers given for eating some of their fruit and vegetables to more potent rewards (e.g. Food Dude-branded pens, pencils, pencil cases) when they ate the whole serving. The intervention has been trialled and shown to be effective amongst schools in socially deprived and non-deprived schools, though it is noted that the context and method of reward delivery were critical to the scheme’s success over the longer term. The context in which the rewards were given in these trials was designed to avoid coercive or negative associations; they focused on the intrinsic virtues and enjoyment of eating fruit and vegetables, extolled by the Food Dudes, and rewards were presented as positive indicators of children’s positive achievements in, for example, keeping the ‘Life Force’ strong. Teachers were asked to use the rewards as marks of achievement, accompanying them with positive encouragement and praise, rather than as a bribe to encourage them to eat more of the fruit and vegetable portions.

NU Spaarpas Initiative, the Netherlands; Seyfang (2006)

This scheme was piloted in the city of Rotterdam from 2002 to 2003 with the aim of promoting pro-environmental consumer behaviour. Within the scheme, “green points” are earned when city residents separate their waste for recycling, use public transport, or shop locally. Extra points can be earned by buying “ethical” products. These points can be redeemed for public transport tickets or

discounts on sustainable products; alternatively, they can be donated to charity. The points circulate in a closed-loop system, and card scanners in participating shops feed data into a central set of accounts. In October 2003, 10,000 households owned the card, over 100 shops were participating, and 1.5 million points had been issued. It was a partnership between local government, local businesses, and non-governmental organisations. The pilot NU project cost €2 million to establish and run during the trial period. It is reported to have resulted in the following benefits: (a) supporting localisation; (b) reducing the local environmental footprint; (c) encouraging positive shifts in consumer behaviour; (d) channelling collective action through the public sector; and (e) creating new institutions of exchange (Seyfang, 2006).

Spice, multiple locations across England and Wales; University of Wales, 2008

Spice is a social enterprise active in England and Wales that develops agency-related time banking systems for communities and public services, covering various activities such as housing, schools and local communities. For example, in housing projects social housing tenants can earn credits by contributing to a series of residential activities. These include community programmes (e.g. organisation of social events), community support (e.g. childcare, health groups) and core tenant participation (e.g. interview panels, board meetings, sub-groups). Tenants can exchange Spice time credits for leisure, learning and recreation services organised and brokered by the landlord in partnership with local community centres. In part, the credits utilise “excess capacity” in local venues, such as spare seats at local rugby matches. In addition, tenants can exchange credits among themselves with services and activities.

Similarly, school projects are based around ‘Time School’ credits, which may be earned by students, parents and community members who offer support to their school community. The credits may be redeemed for tickets to school concerts, use of school IT facilities, local leisure and recreational services. The ‘Time School’ scheme has been introduced to four secondary schools (namely, Glyn Derw High School, Michaelston Community College, Pontypridd High School, and Tonypandy Community College) with the purpose of promoting an active culture and cohesion between the schools and their wider communities.

Orange Rockcorps, multiple locations in the US, UK, France; personal correspondence

The RockCorps movement was started in the US in 2005; the idea is that four hours of volunteering in the community is rewarded with music: tickets to a unique gig cannot be bought, but only earned through volunteering. Whilst the movement started in the US, it has now spread to France and the UK. In 2008 RockCorps was launched in the UK, working in partnership with Orange, Blackberry and Channel 4. The last concert was held at the Wembley Arena in July 2011, attracting over 11,000 volunteers, all of whom had dedicated at least four hours of time to an Orange RockCorps volunteering project. Orange RockCorps broadened the scheme with the launch of the “Orange RockCorps Collective” in 2009. Mindful that not everyone can get to London for a specific gig and may not live near an Orange RockCorps project, the Collective scheme rewards people who have volunteered four hours of their time to any genuine charity with a Ticketmaster voucher, which they can redeem for a gig of their choice (once the volunteering story has been validated).
