G77

Reporting from Barcelona, Spain

A new global warming pact coming out of Copenhagen in December must be a legally enforceable treaty, not just promises from politicians, developing nations said at the Barcelona talks on Wednesday.

The statement was in response to rich nations' newest push for a "politically binding" deal, the idea being it's way too late to get a legal one on the books by December.

Political agreements "are worth very little," said Lumumba Stanislaus Di-Aping (above), the Sudanese chair of the Group of 77 and China.

"Tell me of any politician who delivered on his political manifesto?"

Danish Prime Minister Lars Lokke Rasmussen started the firestorm on Monday when he said, "We are working very strongly to reach a politically binding agreement in Copenhagen." Swedish Prime Minister Fredrik Reinfeldt added to that on Wednesday, stating on Swedish Radio that a legal treaty is "simply not possible to deliver."
