Background and Introduction
• The NCCRP calls for the defining of desired sectoral mitigation contributions and the defining of “Carbon Budgets for significant greenhouse gas (GHG) emitting sectors and/or sub-sectors of the economy. This should be informed by:
o an in-depth assessment of the mitigation potential,
o best available mitigation options,
o science, evidence and
o full assessment of the costs and benefits”
• The 1ST MPA was done in 2013- 2014 and approved by parliament in 2014

1) Project national greenhouse gas emissions into the future
2) Identify and analyse mitigation opportunities
3) Assess the socio-economic and environmental impacts of the identified mitigation options

MPA 2014 Shortcomings 1 Shortcomings • It did not cover all the sectors:
Industry: limestone production and dolomite, soda ashproduction and use, asphalt roofing, road paving withAsphalt, glass production PF6 used in aluminium andmagnesium, food and drink industries, production ofHFCs, PFCs and SF6, an consumption of HFCs, PFCs andSF6, Transport: maritime transport associated with inlandand coastal navigation as well as shipping; Waste(industrial waste); these will however depend on theavailability of data;

MPA 2014 Shortcomings
• It was not done according to IPPC sectors
• The modelling was mainly done on Excel which makes it difficult to follow
• Number of errors were identified in the Excel model
A Decision was taken to develop a user-friendly model (Lumina Analytica)

Changes: Overall assumptions
• Populationo Income category split: updated to include middle income
and linked to GDP growth
• Emission factors o Corrected to be consistent across the modelo Aligned with the Technical Reporting Guidelines
• Exchange rateso Original MPA applied 2010 exchanges to all costso Updated version includes historic exchange rates from
2000 – 2015

Changes: Overall assumptions
• Discount Rate
o The original MPA uses a discount rate of 11.3%.
o The update include a choice of discount rate of 1%, 3%, 5%, 8.2% as well as 11.3%

Changes in Methodologies
MPA 2014
• GHG emission projectionstied to forecasted economicgrowth (moderate growth to2050 = 4.2%)
• IRP used as the basis forelectricity demand
-
MPA UPDATE 2018 • Realistic growth projections
per subsector: For somesectors, using GDPprojections to projectproduction output isnonsensical (Similar approachadopted for the Pathwaysproject)
• Production across sectors arelinked within the model: Forexample Coal demand forelectricity generation is linkedto coal mining output.

Changes in Methodologies Road Transport:
• The 2014 MPA used the Ricardo-AEA’s SULTAN modelwhich was based on the UK data, they could not sharethis with us (IP).
• The transport sector was built from scratch, this is basedon a vehicle parc model developed by the ERC inpartnership with SANEDI
• Both models require some adjusting to ensure theywork together
• Still to be linked with the power sector to includeelectricity use from electric vehicles

Electricity sector
• IRP no longer used as a basis for the electricitysector, however costs are aligned to the draft IRP2016 this will be update to 2018 IRP
• This is a work in progress
– We are collaborating with the IRP modelers to assess for system adequacy for the power sector

Results:
• Results can be viewed in many ways:
– At 5 year intervals: 2020 25, 30… 50
– By subsector, sector, IPCC Category
– By measure type: e.g. energy efficiency, fuel

Challenges • Lack of data remains an issues :
– Costs : capital , O&M
– Industry limestone production and dolomite, soda ashproduction and use, asphalt roofing, road paving with Asphalt,glass production PF6 used in aluminium and magnesium, foodand drink industries, production of HFCs, PFCs and SF6, anconsumption of HFCs, PFCs and SF6, Transport: maritimetransport associated with inland and coastal navigation as wellas shipping; Waste (industrial waste); these will howeverdepend on the availability of data;
• Building Internal Capacity

Future modifications will consider :
Input assumptions : Relevant official governmental sources, stakeholder inputs
Activity data: GHG inventory and direct from industry, research, government entity
Obtaining costs and net benefit information for new sectors
Modelling methodology: external model reviewers, internal studies

NEXT STEPS
• Finalise the power sector model & integrate with other sectors
• Stakeholder engagement (end Jan /beginning of February)
• Final MPA digital model ( March 2019)

Benefits of Analytica over Excel
• Better suited for multiple dimension spreadsheets/models
• Easier to use common assumptions – updates across model components– E.g. emission factors, exchange rates
• More difficult to make mistakes (particularly around cell references)– Analytica has a number of ways to preventing formula
errors
• Visual representation of your model• Very good annotation functions
