Global Climate Change Negotiations: A Perspective on Intergenerational and Social Equity P.R. Shukla
NORTH-SOUTH EQUITY: UNFCCC Article 3.1 M “common but differentiated responsibilities” Article 3.2 Special attention and considerations for parties: N “that would have to bear a disproportionate or abnormal burden under the Convention” N “vulnerable to the adverse effects of climate change”
Carbon Emissions per Capita (1993) Africa India China Other Asia Latin America Other Europe EU12 Former USSR Japan Australia USA Canada Carbon emissions per Capita (tC/cap)
Historic CO 2 and Methane Contribution (%)
EFFICIENCY: UNFCCC Article 3.3 “policies and measures to deal with climate change should be cost-effective so as to ensure global benefits at the lowest possible cost”

PROTOCOL WITH INCOME BASED ENTRY AND TECHNOLOGY CONDITIONS EQUITY CRITERIA / Non- Annex I enters when income (in PPP) equals 2020 Annex I Income TECHNOLOGY CONDITIOS TECHNOLOGY CONDITIOS (Annex I to implement after 2020) / New Fossil Power Plants to scrub and dispose carbon from exhaust / New Synthetic fuels to capture and dispose carbon released in conversion WHEN SOME NON-ANNEX JOIN IN? / China in 2045; India in 2062EFFICIENCY / 30 percent expensive than most cost-effective mitigation
SEPARABILITY OF EQUITY AND EFFICIENCY COASE THEOREM Stipulates çin absence of transaction costs, market exchange will lead to efficient resource allocation regardless of distribution of rights Implies çthe process of minimizing burden size is independent of the burden sharing scheme
SEPARABILITY OF EQUITY AND EFFICIENCY COASE THEOREM: TWO INTERPRETATIONS 1. Neo-Classical/ Northern World View Equity is irrelevant to global co-operation 2. Developing Country Perspective Efficiency is simple - just needs agreeing on instruments. Equity (sharing of burden) is vital
Sharing the Burden 1. Stabilization Burden shall be substantive 2. Significant mitigation shall be in NA-I (“Where” Flexibility for Cost Effectiveness) (“Where” Flexibility for Cost Effectiveness) 3. Transition from Cost to Welfare Effectiveness (“Justice” in Burden sharing is vital)
Conclusions: A Fair Agreement Burden Sharing JExplicit Burden Sharing Regime Fair Competition JPolluter Pays JMarket Price for CDM Mitigation Minimize Welfare Losses JAbility to Pay JCompensation for Impacts Precautionary Principle JHedge against extreme events JProtect most vulnerable
“ It is the nature and the advantage of strong people that they can bring out the crucial questions and form a clear opinion about them. The weak always have to decide between alternatives which are not their own.” Dietrich Bonhoeffer German Philosopher, anti-Nazi thinker (executed in Flossenburg concentration camp, April 9, 1945)
