World leaders have recognized that nothing will be completed in Copenhagen on the environment. The second best plan - according to them - is to use Copenhagen as a springboard and complete a real agreement shortly after. Without the time line pressure it's going to be difficult but maybe they will surprise us.
Postponing many contentious decisions on emissions targets, financing and technology transfer until the second-stage, leaders will instead try to reach a political agreement in Copenhagen that sends a strong message of intent.
While this falls short of hopes that the meeting would lock in place a global action plan to replace the Kyoto protocol, it recognises the lack of progress in recent preparatory talks and the hold-ups of climate legislation in the US Senate.
Michael Froman, US deputy national security adviser for economic affairs, said: "There was a realistic assessment ... by the leaders that it was unrealistic to expect a full internationally legally binding agreement to be negotiated between now and when Copenhagen starts in 22 days."
