  1. Agenda Markus Amann Methodology Fabian Wagner Initial results for emissions from energy use and industrial activities Ian McCallum Estimates of mitigation potentials in the LULUCF sector Anthony Patt The interactive Mitigation Efforts Calculator You: Discussion!

  2. Comparing GHG mitigation potentials and costs for Annex 1 countriesMethodology for emissions from energy use and industrial activities Markus Amann International Institute for Applied Systems Analysis (IIASA)

  3. Methodology Bottom-up approach • Detailed technical level, • all gases and sectors, • systems approach, • starting from IEA, FAO projections of economic activities, • technical, economic and market potentials (before trading). Based on earlier work with IIASA’s GAINS (Greenhouse gas – Air pollution Interactions and Synergies) model

  4. Advantages and disadvantagesof bottom-up approach Pro’s: • Explicit accounting of structural differences between countries at a technical level • Baseline projection of economic activities provided by countries or international organizations • Participatory approach Con’s: • No behavioural changes • No macro-economic feedbacks

  5. Disaggregation of emission sourcesin domestic and industry sectors • Domestic sector: • Residential/Commercial energy use, • Heating+ventilation+AC/Water heating/Cooking/Lighting/Large appliances/Small appliances, • Up to 10 climate regions, • Flats/Single family houses, • Built before/after 2010 • Industry: • 6 sectors:Iron and steel, Non-ferrous metals, Non-metal minerals, Chemicals, Pulp and paper, Other industries • For each sector up to 13 products:(e.g., Raw steel, Finished products, Scrap supply, Coke oven coke, Sinter, Pellets, Pig iron, Direct reduced iron, Open hearth furnace, Basic oxygen, Electric arc furnace, Casting, rolling finishing, Thin slab casting)

  6. Estimating mitigation potentialsFour steps • Inventory of ~300 mitigation measures, with technical and economic features

  7. Mitigation measures~300 options in each country Structural measures CO2 measures N2O measures F-gas measures CH4 measures

  8. Estimating mitigation potentialsFour steps • Inventory of ~300 mitigation measures, with technical and economic features For each source sector in each country: • For 2005: Match emissions reported to UNFCCC • with activity data from UNFCCC, IEA and national statistics, • adjust implementation rates of mitigation measures.

  9. Estimating mitigation potentialsFour steps • Inventory of ~300 mitigation measures, with technical and economic features For each source sector in each country: • For 2005: Match emissions reported to UNFCCC • For 2020: • Match baseline energy use of IEA World Energy Outlook 2008 • with activity rates projected by IEA modify implementation rates of energy efficiency measures to reproduce IEA energy projection. • Develop baseline emission projection • adjust implementation rates of mitigation measures as reported in National Communications.

  10. Estimating mitigation potentialsFour steps • Inventory of ~300 mitigation measures, with technical and economic features For each source sector in each country: • For 2005: Match emissions reported to UNFCCC • For 2020: Match baseline energy use and develop baseline emission projection • Determine further mitigation potential • from implementing the best available (energy efficiency and C mitigation) measures that are not assumed in the baseline, • considering constraints on replacement of existing capital stock, structural limits, etc.

  11. Energy intensity of ethylene production

  12. Energy intensity of ethylene production Efficiency frontier

  13. Estimating mitigation costsThree steps: • Determine unit costs for each mitigation option: • Annualized investments + operating costs – savings per unit of reduced emissions • Reflect resource costs without transfers (no taxes, subsidies, profits, transaction costs, etc.) • Alternative interest rates for annualization of investments: • Social (4%/yr) • Private (20%/yr) • For a given mitigation target: • Determine least-cost portfolio of mitigation measures (i.e., including upstream effects), through optimization model • Cost curves: Series of optimizations between baseline emissions and maximum mitigation case

  14. Marginal abatement cost curveAnnex I in 2020, 20% interest rate, excl. LULUCF Maximum mitigation case Baseline emissions Technical potential Market potential(at 20% interest rate) +7% +2% -3% -10% -16% Rel. to 2005 Carbon price (€/t CO2eq) 200 100 0 -100 -200 +3% -2% -7% -13% -20% Rel. to 1990 Analysis not completed yet for: Belarus, Croatia,Turkey, Cyprus, Malta

  15. An initial implementation • For largest Annex 1 countries (98% of 1990 emissions), EU25 presented in aggregate • Based on activity projections of IEA World Energy Outlook 2008 and FAO World Agriculture Perspective • Key assumptions: • Only currently available technologies • Natural turnover of capital stock, no premature scrapping • No behavioural changes • Before trading • LULUCF excluded for now • Initial analysis based on publicly available information, received only limited review by national experts
