1.1.1 The purpose of this technical appendix is to present the methodological and technical detail underpinning the information presented in the main document of the Second Report on Policies and Proposals ( RPP2).
1.1.2 Scotland's annual climate change targets are explicit in the rate of greenhouse gas ( GHG) emissions reduction required each year and the target level of annual emissions that is permitted under the Climate Change (Scotland) Act 2009 over the period 2010 and 2027. The robustness of the evidence base that underpins the potential impacts of policies and proposals is key to ensuring that appropriate decisions can be made on the most effective means of meeting the targets.
1.1.3 This technical appendix provides information on historical GHG emissions in Scotland, the methodology used to estimate future business-as-usual ( BAU) emissions projections and the emissions abatement potential from implementation of policies and proposals. It also provides the basis on which estimates of the required financial investments to deliver the policies and proposals have been derived.
1.1.4 This appendix has three parts:
- Part 1 presents the context in which the RPP2 is set, the statutory targets that are to be achieved and how progress against those targets is measured.
- Part 2 presents historical emissions data for Scotland and the methodology adopted to estimate a BAU future emissions projection for Scotland. It also explains the degree to which there are uncertainties associated with estimating future emission projections.
- Part 3 presents the methodologies adopted to estimate the emissions savings, investments and benefits identified for the policies and proposals within each sector.
