  1. Recent developments at CIAM Markus Amann International Institute for Applied Systems Analysis

  2. Issues • Revision of the NEC Directive • Revision of the Gothenburg Protocol • New GAINS features to model energy efficiency improvements and fuel substitution • Marginal costs of GHG mitigation in Annex1 countries

  3. Revision of the NEC directive • NEC report #6 published in July 2008 • Commission has postponed proposal on NEC until further notice • New call for tenders for NEC follow-up analysis published – without specific dates for calculations • New PRIMES 2009 baseline will be released in June 2009; will be used for EC4MACS interim assessment

  4. Revision of the Gothenburg Protocol • Call for national energy projections – deadline May 31, 2009.For appropriate format: contact Janusz Cofala • Baseline projection for WGSR in September 2009; traditional GAINS analyses will be complemented by quantifications of impacts by the various WGE Task Forces and Centres • Set of emission control scenario calculations for EB December 2009

  5. EC4MACS schedule • Model documentations are now on the Internet (www.ec4macs.eu) • Internet consultation on methodology has been started – deadline for comments: June 15, 2009 • Interim assessment (full model chain with recent PRIMES + CAPRI baseline projections): August 31, 2009 • EC4MACS review workshop (together with Task Force on Integrated Assessment Modelling): October 2009

  6. Marginal cost curves for GHG mitigation • GAINS has been used compare GHG mitigation efforts between Annex 1 countries, • all gases and sectors, • at detailed technical level (several 100 source categories, 300+ mitigation measures, etc.) • systems approach (integrated perspective covering demand and supply sectors), • consistent with UNFCCC 2005 inventories • Results, input data and an interactive calculator freely available in the public domain: http://gains.iiasa.ac.at

  7. New GAINS structure for domestic sectorto facilitate assessment of energy efficiency improvements Separate treatment of Residential and Commercial energy use Needs distinguished: • Space heating + ventilation + Air conditioning (HVAC) • Water heating • Cooking • Lighting • Large appliances • Small appliances, Up to 10 climate regions, Flats/Single family houses, Built before/after 2010, For each source category: • Up to 3 efficiency stages • Switch to less carbon-intensive fuels (coal to gas or biomass, solar…), • District heat with CHP instead of local boilers

  8. New GAINS structure for industrial sectorto facilitate assessment of energy efficiency improvements - Iron and steel • Raw steel, Finished products, Scrap, Coke oven coke, Sinter, Pellets, Pig iron, Direct reduced iron, Open hearth furnace, Basic oxygen, Electric arc furnace, Casting, rolling finishing, Thin slab casting, Other • Non-ferrous metals • Aluminum (primary, secondary), Other metals (primary, secondary), Other • Non-metallic minerals • Cement (of which clinker), Lime, Other • Chemicals • Ammonia, Ethylene, Chlorine, Other • Pulp and paper • Pulp (from wood, from recovered paper), Paper and paperboard, Other • Other industries Changes in production structure (e.g., primary vs. secondary metals, clinker content in cement) included in the baseline

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

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

  11. 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.

  12. 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.

  13. 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.

  16. 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

  17. 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

  18. An initial implementation • For largest Annex 1 countries (98% of 1990 emissions), EU27 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 • Domestic measures only • LULUCF excluded for now • Initial analysis compiled from publicly available information, received only limited review by national experts up to now
