Interactive demonstration of the FAIR model developed by MNP/RIVM Workshop on Quantitative Tools & Negotiating Capacity Time scales of stabilization Source: IPCC Synthesis Report, 2001 Workshop on Quantitative Tools & Negotiating Capacity Possible temperature trajectories Source: IPCC Synthesis Report, 2001 EU climate target of 2°C above pre-industrial level • 1000 to 1861, N. Hemisphere, proxy data; • 1861 to 2000 Global, Instrumental; • 2000 to 2100, SRES projections Workshop on Quantitative Tools & Negotiating Capacity Linking temperature to concentration Levels of CO2 concentration EU climate target Preindustrial: 280 ppm Current: 360 ppm Source: IPCC Syntheses Report, 2001 Workshop on Quantitative Tools & Negotiating Capacity 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1990 Reference 120% 100% 80% 550ppm 60% 40% 20% 450ppm 0% -20% 400/350ppm -40% -60% -80% 2000 2010 Source: post SRES scenarios (stabilization paths), CO2 only 2020 2030 2040 -100% 2050 Change to 1990 GtC Stabilization pathways Workshop on Quantitative Tools & Negotiating Capacity Approaches • Contraction and Convergence (C&C) • Common but Differentiated Convergence (CDC) • Multistage • South North Dialogue – Equity in the greenhouse • Brazilian Proposal • Sectoral approaches • Triptych Workshop on Quantitative Tools & Negotiating Capacity Contraction and Convergence • Contraction: Definition of global emission path (e.g 450ppmv) • Convergence: Per capita emissions of all countries converge by 2050 Emissions per capita (tCO2eq./person) 30 Annex I 25 Global total Non-Annex I 20 15 10 5 0 1990 2000 2010 2020 2030 2040 2050 2060 2070 2080 2090 2100 Workshop on Quantitative Tools & Negotiating Capacity Common but differentiated convergence • Three stages – No commitments – Positively binding emission targets – Convergence to an equal per capita level within e.g. 40 years as of entry – World average GHG/cap N. Höhne, M. den Elzen, M. Weiß “Common but differentiated convergence (CDC) - A new conceptual approach to long-term climate policy” submitted to climate policy GHG/cap • Threshold: Threshold Time Workshop on Quantitative Tools & Negotiating Capacity Multistage approach • Participation in e.g. four stages: Reduction Moderate reduction No commitments Sustainable development policies and measures • Countries “graduate” to a next step, if threshold is passed, e.g. emissions/cap Workshop on Quantitative Tools & Negotiating Capacity South North Dialogue Quantitative commitment Qualitative commitment Financial support 1. Least developed countries - SD PAMS optional Receive payments 2. Other developing countries - SD PAMS obligatory, co-funded Receive payments 3. Rapidly industrializing developing countries Limitation if funding provided SD PAMS obligatory, co-funded Receive high payments 4. Newly industrialized countries Limitation SD PAMS obligatory Co-funding 5. Annex I but not Annex II Absolute reduction - Low/no payments 6. Annex II Strict absolute reduction - Make high payments • Thresholds: CO2/GDP, GHG/cap, emission growth, cumulative emissions, GDP/cap, HDI; show members of the groups • Adaptation commitment Workshop on Quantitative Tools & Negotiating Capacity Brazilian proposal • Calculate countries’ contribution to temperature increase • Countries reduce proportional to their contribution to temperature increase Workshop on Quantitative Tools & Negotiating Capacity Sectoral approaches • Discussed quite actively in various fora, but their exact specification is often unclear • The common goal: avoid competitiveness concerns Options: • Goal for one global industry sector, e.g. the automobile industry • Emission standard or benchmark for a particular sector described, e.g., in gCO2/t steel • Emission targets are defined for all individual sectors as function of their respective output (e.g. t of steel, kWh produced, etc.) and added to a national emission target Workshop on Quantitative Tools & Negotiating Capacity Industry Adjusted BAU production growth with efficiency improvement Electricity Adjusted BAU production growth with limit on sources Domestic Converging per-capita emissions Fossil fuel production Decline to low level Agricultural Percentage reduction below BAU Waste Converging per-capita emissions Land use change and forestry Decline to zero (here excluded) National emission target Triptych Workshop on Quantitative Tools & Negotiating Capacity Overview of tools CAIT Emission allocation FAIR X (X) Contraction and Convergence (C&C) X X Common but Differentiated Convergence (CDC) X (X) Multistage X X South North Dialogue – Equity in the greenhouse X (X) Country level historical data XX EVOC Brazilian Proposal Sectoral approaches Triptych Mitigation costs X (X) X (X) X Workshop on Quantitative Tools & Negotiating Capacity Content 1.

Not acceptable due to different national conditions and development stage • All countries do the same: increase efficiency, reduce fossil fuels in electricity production and converge in domestic emissions. • Triptych was developed to calculate the respective emission allowances • Values served as the basis for the negotiations within the EU.

Quantitative Tools & Negotiating Capacity Conclusions • Most sophisticated approach to share emission allowances • Can be applied to any group of countries (here globally) • For stabilization at 450 ppmvCO2 applied globally: – Substantial reduction requirements for the industrialised countries, especially those more inefficient or slower growing – Substantial emission increases are allowed for most developing countries, however, mostly below their reference scenarios • Weaknesses: – Rather complex and requires many separate decisions – Requires much data – Modelling requires many assumptions, including projections of production growth rates for heavy industry and electricity • Strengths: – Can accommodate national circumstances through sectoral detail – Explicitly allows for economic growth and improving efficiency – Successfully applied (on EU level) as a basis for negotiating targets Workshop on Quantitative Tools & Negotiating Capacity Sectors of Triptych version 6.0

Emission trading possible • Simple: Simple rules, only countries with high per capita emission need to participate Workshop on Quantitative Tools & Negotiating Capacity Conclusions • New concept for an international climate regime • Simple, but eliminates two concerns often voiced in relation to C&C: – Delayed participation of DCs – No resource transfer and hot air • For 450 CO2: participation at roughly world average and convergence to 3 tCO2eq./cap within 40 years • For 550 CO2: participation at roughly 50% above global average and convergence to 4.5 tCO2eq./cap within 40 years • Additional mechanisms needed for vulnerable developing countries to adapt to climate change. • Future decisions on post 2012 regime guided CDC principles: – Developed countries per capita emissions converge – Developing countries do the same but delayed and conditional to developed country action.

Tools & Negotiating Capacity Conclusions • EU target of 2°C above pre-industrial levels: below 450 ppmv CO2 (average climate sensitivity) • If no efforts are made to reduce emissions and if the Kyoto Protocol is not implemented, there is a significant probability that staying below 450 ppmv CO2 would be out of reach already as of 2020. • To keep 450 ppmv CO2 within reach – Developed country emissions would need to be reduced substantially – USA needs to be involved in the system most likely with stronger action than the national target of 18% intensity improvement in 10 years – Developing country emissions need to deviate from the reference as soon as possible, for some countries even as of 2020 (Latin America, Middle East, East Asia) • Reduction difference between

specially in Latin America and Middle East Workshop on Quantitative Tools & Negotiating Capacity Conclusions • 450 ppmv CO2 concentrations is not a ‘safe’ option: – – – – – Likely to result in global temperature increase above 2°C Coral reefs affected, Considerable melting of ice, Increased extreme whether events, Risk of large scale singularities low but not excluded • Stabilization requires global emissions to drop below 1990 levels (for 450 ppmv CO2 within a few decades) Workshop on Quantitative Tools & Negotiating Capacity 5.
