No money, no deal on climate change

Developing nations, who say wealthy countries are largely to blame for climate change to date, want cash to help them green their economies. Money to adapt to rising seas and greater extremes of weather is also essential, they say.
 
Without cash and clean-energy technology, they see no point in taking anything more than voluntary steps to curb the growth of their greenhouse gas emissions.

Rich nations have so far failed to put significant sums on the table and instead talk of "fast-start" cash in Copenhagen for initial adaptation and technology transfer programmes.
 
Details on larger and longer-term funding would come later but there remains disagreement on whether this should be mostly public money or raised through carbon markets and levies on shipping and aviation fuels.
 
The United States says its hands are tied until the Senate passes a climate bill. The European Union will likely have clarity on funding after a leaders' meeting in a few weeks.
