Post 2012 Climate Regime
"In this report, we address these questions (below) and explore the economic and environ-mental implications of the pledges and NAMAs submitted under the Copenhagen Accord (UNFCCC 2009). Furthermore, we analyze and assess the comparability of efforts of Annex I mitigation pledges compared to a range of socio-economic indicators that may provide a basis for a “fair” effort sharing agreement to achieve a given target. The analysis was performed using i) the ClimStrat tool which provides a flexible, ready-to-use analytical tool based on marginal abatement cost curves resulting from a partial equilibrium framework, and ii) the GHG effort sharing tool which has been designed to allocate GHG reduction targets for the Annex I Parties and uses a transparent set of indicators to reflect national circumstances when sharing the necessary reduction effort.
Four key questions arise:
- Do the pledges add up to the emission reductions required necessary by science?
- What are the costs associated with meeting the given targets?
- Are the proposed emission reduction efforts of Annex I parties comparable?
- What would comparable efforts look like taking country-specific socio-economic indicators into account?"
