Methodologies, Technical Resources and Guidelines for Mitigation

1. Methodologies, Technical Resources and Guidelinesfor Mitigation Festus LUBOYERA and Dominique REVET Programme Officers UNFCCC secretariat (FLuboyera@unfccc.intand DRevet@unfccc.int)

2. (1) Contents • Deciding on the Methodological Approaches for mitigation analysis • Steps to follow • Structure of the analysis • Technical Resourcesand Guidelines (*) Almost all Partiesincluded information on “programmes containing measures” that could contribute to addressing climate change. Furthermore, they also provided information on methodologies, scenarios, models and criteria used for the assessment.

3. (2) Deciding on the Methodological Approaches for Mitigation Analysis • Decide on the methodological approach to be adopted for the analysis • “Bottom-up” or “Top-down” – checksuitability, strengths and weaknesses • Select the analytical tool/model to be used • Consider the requirements of the analysis such as: importance of the sector considered, data availability, skills required/available, etc.

4. (2) Deciding on the Methodological Approaches for Mitigation Analysis (Cont.) • Analytical structure of the Analysis • Evaluation of national social and economic development framework for climate change mitigation (Slide 3) • Baseline scenario projection – no policies in place on GHG reduction (Slide 4) • Mitigation scenarios projections – taking into consideration the baseline scenarios (Slide 5) • Macroeconomic assessment (Slide 6) • Implementation issues (Slide 7)

5. (3) Evaluation of national social and economic development framework • Comprehensive description of national framework for CC mitigation including: base year statistics on GDP structure, social conditions, energy balance, aggregate GHG inventory, major land use activities, population, etc. • Evaluation of main national economic and social national development trends and the GHG emissions that are expected to occur as a result of economic development • Overview of mitigation reports together with other climate change studies including impact, adaptation, GHG inventories

6. (4) Baseline scenario projection • Select/develop modeling approach • Choose base year and time horizon • Definebaseline scenario – baseline economic and demographic trends and assumptions • Examinetrends in energy consumption, production, technology, fuel prices land use change and forestry

7. (5) Mitigation scenarios projections • Identification of mitigation options related to the most important future sources and sinks of GHGs • Screening of mitigation options • Assessment of reduction potential and the related cost of mitigation scenarios • Integration of GHG reductions and costs across measures and sectors, through construction of GHG mitigation marginal cost curves

8. Sample Format for the Reporting of Mitigation Options

9. (6) Macroeconomic assessment • Qualitative description of main macroeconomic impacts of national climate change mitigation strategies • Assessment of key macroeconomic parameters

11. (7) Implementation issues • Identification of main implementation requirements including financial support, technologies, institutional capacity building, regulation policies and further improvements of the national decision framework

12. (8) Some Technical Tools Examples of “Bottom–up” models • COMAP (COmprehensive Mitigation Assessment Process for forestry): spreadsheet model • COPATH (Carbon Pasture Agriculture Total Harvesting): spreadsheet model for the estimation of carbon flows associated with forest use • ETO (Energy Technology Optimization): optimization model which compares energy supply sources to identify the lowest cost option • EM (Environmental Manual for power development): tool for the inclusion of environmental and cost data into decision-making for energy projects, especially in developing countries • GACMO (Greenhouse GAs Costing MOdel): a spreadsheet module for project-based mitigation analysis

13. (8) Some Technical Tools (Cont.) • LEAP (Long-range Energy Alternatives Planning system): end-use accounting modeling system for energy • STAIR (Services, Transport, Agriculture, Industry and Residential energy model): accounting model for long-term mitigation scenarios Examples of “Top-down” models • MARKAL-MACRO (MARKet ALlocation MACRO-economic model): an energy-economy-environment optimization model (combined bottom-up and top-down approaches) • ENPEP (Energy and Power Evaluation Program): iterative equilibrium model for the energy system (partial bottom-up characteristics)

14. Examples of Analytical Tools Available for Mitigation Assessments

15. (9) Selecting a Model • The model should be simple enough (i.e.: not hinder analysis process) • Simple spreadsheets can be constructed for a specific analytical purpose • Complex models should be supported by training • Output of the model should be useful to the stakeholders (especially for national planning).

16. Key Design Features of Selected Sector Models

17. (10) Some Useful Technical Resources • IPCC Technical Paper I - Technologies, Policies and Measures for Mitigating Climate Change • IPCC 3rd Assessment Report - Climate Change 2001: Working Group III: Mitigation • UNEP/RISO: Economics of GHG Limitations • GHG Mitigation Assessment : A Guidebook (US Country Studies Program (*) TheCD-Romof this workshop contains a number of guidelines as well as software such as LEAP and COMAP together with their manuals and some training exercises in various languages.
