BONN, Germany — The United States, China and Brazil on Friday joined dozens of other nations criticizing a draft climate treaty issued in Bonn, leaving in place divisions holding up a United Nations agreement on global warming.
Delegates urged the diplomat who produced it, Zimbabwe's Margaret Mukahanana-Sangarwe, to revise it.
The document is intended to guide discussions leading up to an eventual treaty aimed at curbing greenhouse gas emissions from factories and power plants. It also would channel aid to nations most at risk and encourage the spread of clean energy technologies such as wind and solar power.
"The text contains a number of ideas that the United States could not accept in an agreed outcome," U.S. negotiator Trigg Talley said.
Chinese delegation chief Su Wei called the text "unbalanced." Yemen, which spoke on behalf of the G-77 group of developing nations, objected, along with India and Brazil. So did Spain, speaking for the European Union's 27 members.
Without a global agreement, the 1997 Kyoto Protocol's limits on greenhouse gases for more than 35 nations will expire in 2012, ending the only global restrictions on the heat-trapping gases that scientists have linked to rising global temperatures.
Delegates will meet again in Bonn in August.
