US President Barrack Obama and other world leaders on Sunday supported delaying a legally binding climate pact until 2010 or even later. This came under a compromise deal for next month's Copenhagen Summit. Danish Prime Minister Lars Rasmussan told the leaders that the Copenhagen agreement should mandate continued legal negotiations and set a deadline for their conclusion. Rasmussan's two-step plan would pave the way for a political accord at the December talks, to be followed by debates over legally binding commitments over targets, finance and technology transfer on a slower track, though still with a deadline. The move will give breathing space for the US Senate to pass carbon-capping legislation, allowing the Obama Administration to bring a 2020 target.<br/><br/>
