(convergence to eff. benchmark) Electricity BAU production growth with limit for renewables, CHP, coal and gas National emission target Values served as the basis for the negotiations within the EU (1997)

7 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 7 Differentiated participation in convergence Source: Ott et al. 2004 like South Korea, Saudi Arabia, Singapore like Argentina, Brazil, China, Mexico, South Africa like Egypt, India, Indonesia, Nigeria, Pakistan like Afghanistan, Bangladesh, Tanzania, Zambia).

8 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 8 1.Strong scenario: Early convergence to final convergence level (p.c. emissions or energy eff. level) (large coalition) 2.Medium scenario: Medium convergence to final convergence level; delayed convergence for the developing countries Before participation DCs implement Sustainable development policies and measures or no-lose targets (10% below BaU) Differentiated participation in convergence

9 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 9 Industry Considerable per capita growth in industrial production from IPCC SRES scenarios Energy efficiency varies between countries Differentiated convergence of aggregated energy efficiency index (EEI) –EEI: specific energy consumption (SEC) divided by SEC under best current practices (reference SEC) –Convergence-level 0.7 (bottom-up studies)

10 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 10 Differentiated convergence in Energy Efficiency Index Convergence level 0.7 EU, USA: 2050 India 2070 Medium scenario

11 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 11 Electricity Growth in electricity generation from IPCC SRES scenarios Energy mix varies between countries Emission factors per fuel vary between countries

12 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 12 Differentiated convergence of emissions/kWh Convergence level 600 gCO2/kWh Medium scenario

13 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 13 Decrease in the share of coal and oil in the fuel mix by 90% in 2050 Medium scenarioReduction by CCS, renewables etc.

14 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 14 Sectoral development: Global 450 CO2-eq case A1B scenario

15 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 15 Medium scenario corresponds with stabilisation 550 ppm CO 2 eq, and strong with 450 ppm CO 2 eq Reduction of countries are given in MNP report (www.mnp.nl\en)

16 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 16 Strengths and weakness Weaknesses: Rather complex Requires much sectoral data Requires agreement on projections of production growth rates for industry and electricity Strengths: compatible with technical emission reduction potentials Account for national circumstances Allows level playing field industry Account for equity principles Explicitly allows for economic growth and improving efficiency Successfully applied (on EU level) as a basis for negotiating targets allows delayed developing country participation

17 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 17 Conclusions reductions are ambitious but compatible with technical reduction potentials 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

20 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 20 Introduction 1997: How should the EU Kyoto target of –8% be shared among the individual member states? All countries reduce the same at –8%? 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.

21 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 21 Methodology: the FAIR 2.1 country model Base year data (1990-2005): Emissions: IEA database (CO 2 ) and EDGAR 3.2 (non-CO 2 ) All Kyoto gases, excluding land use change and forestry, including international transport Future population, GDP and emissions scenario for countries IMAGE IPCC SRES scenarios at 17 regions Using an improved downscaling method Tries to deal with the limits of present down-scaling methods

22 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 22 Domestic Domestic per capita emissions vary substantially between countries Triptych 7.0: Participating countries –Differentiated per capita emissions converge to 1.5 tonCO 2 /capita.year

25 Michel den Elzen, The Triptych approach revisited, MNP report, see: www.mnp.nl/en/publications/2007/ 25 Agriculture Large increase in emissions expected in developing countries Stabilization expected in developed countries Emission reduction options available Triptych 7.0: Reduction below reference emissions by a percentage (by 2050 -30% for low income countries, -40% for high income countries)
