Why did Copenhagen fail to deliver a climate deal?
The summit failed to deliver a way to halt dangerous climate change
About 45,000 travelled to the UN climate summit in Copenhagen - the vast majority convinced of the need for a new global agreement on climate change.
So why did the summit end without one, just an acknowledgement of a deal struck by five nations, led by the US.

2. THE US POLITICAL SYSTEM
Just about every other country involved in the UN talks has a single chain of command; when the president or prime minister speaks, he or she is able to make commitments for the entire government.
Not so the US. The president is not able to pledge anything that Congress will not support, and his inability to step up the US offer in Copenhagen was probably the single biggest impediment to other parties improving theirs.
Viewed internationally, the US effectively has two governments, each with power of veto over the other.
Doubtless the founding fathers had their reasons. But it makes the US a nation apart in these processes, often unable to state what its position is or to move that position - a nightmare for other countries' negotiators.
