U.N. climate talks advance, poor urge more CO2 cuts

BONN, Germany (Reuters) - Climate talks made progress on Friday towards a new U.N. treaty to curb global warming but ended far short of calls by developing nations for the rich to make deeper cuts in greenhouse gas emissions.

Four years of talks to widen the existing Kyoto Protocol have struggled to agree on how to share the cost of efforts to curb greenhouses gas mainly emitted by burning fossil fuels.

The United States and Europe warned in closing remarks on Friday that the private sector would finance the climate fight, not their governments.

"I look back on this as a significant session that has advanced our work in important ways," Yvo de Boer, head of the U.N. Climate Change Secretariat, told a news conference at the June 1-12 talks among 183 nations in Bonn.

He said governments staked out far clearer views after their first review of a draft legal text of the treaty due to be agreed in Copenhagen in December to succeed Kyoto.

But developing countries called for more, despite the global recession.

"We finally managed to have a positive exchange on the numbers" for developed nations, China's climate ambassador Yu Qingtai told Reuters. "But still we hear repeated statements resisting calls for further meaningful cuts."

China and many developing nations want the rich to cut by at least 40 percent below 1990 levels by 2020 to avoid the worst effects of global warming such as droughts, floods and rising sea levels.
