Rich and poor nations alike criticized a new blueprint for a U.N. climate treaty on Friday as two weeks of talks among 185 countries ended with small steps toward an elusive deal.

A streamlined climate draft, meant to help talks on a new pact, cut out some of the most draconian options for greenhouse gas and dropped all references to “Copenhagen” — where a U.N. summit in December fell short of agreeing a treaty.

“The group is dismayed that the … text is unbalanced,” developing nations in the Group of 77 and China said in a statement. Several of them said the 22-page text wrongly put emphasis on greenhouse gas curbs by the poor, not the rich.
