With less than a week to go, significant differences remain between the aggregate emissions reductions from current national proposals and the mitigation targets released yesterday in a draft text at the UNFCCC climate talks in Copenhagen. This draft text from the Ad Hoc Working Group on Long-Term Cooperative Action (AWG-LCA) includes greenhouse gas emissions reduction targets that could limit global temperature increase by 2100 to 2.0°C (3.6°F) or less, relative to pre-industrial temperatures. However, current proposals from individual countries for their own actions would lead to temperature increase of approximately 3.8°C (6.8°F) in the same period. Achieving the potential declared in the draft texts will require sufficient commitment to financing, technology transfer, monitoring, verification, and accountability to allow nations to commit to and achieve higher reduction targets than they have currently put on the table. This analysis does not seek to analyze the political viability of the draft text or make any judgment as to the sufficiency of any elements of the draft other than the emissions reduction targets specified.
