The US is trying to block sections of a draft agreement on climate change prepared for next month's G8 summit.
Washington objects to the draft's targets to keep the global temperature rise below 2C this century and halve greenhouse gas emissions by 2050.
The draft, prepared by the German G8 Presidency, says action is imperative.

Bush's administration has repeatedly pushed voluntary agreements as an alternative. The US is a key player in the Asia-Pacific Partnership on Clean Development and Climate, a six-nation pact which promises greenhouse gas mitigation without targets.
US officials are also questioning the draft's call for the establishment of a global carbon market. Many observers believe that such a market can only be effective if there are binding caps on emissions.
"I think the real objective (of the US negotiators) is not just to keep the lid on and have nothing happen while President Bush is in office, but they are trying to lay landmines under a post-Kyoto agreement after they leave office," commented Philip Clapp, president of the Washington-based National Environmental Trust, who has seen the US's proposed amendments.
