Keep climate promises - Cameron
London - British Prime Minister David Cameron said the climate agreement struck in Mexico on Saturday represented a success but warned that countries had to stick to their promises.
Cameron said in a statement that following the deal struck in Cancún there was still some tough ground to cover in the run-up to the climate conference in SA in a year's time.
"The Cancún agreement is a very significant step forward in renewing the determination of the international community to tackle climate change through multilateral action," he said.
"Now the world must deliver on its promises. There is more hard work to be done ahead of the climate change conference in South Africa next year.
"I am clear that Britain will meet its international obligations. This will be the greenest ever British government. And I will continue to make the case for a global, comprehensive and legally-binding climate agreement."
He said Mexican President Felipe Calderon had shown "tremendous skill" in producing a consensus.
The global talks on climate change set up a new fund to manage billions of dollars in aid to poor nations in a hard-fought package urging deep cuts in industrial emissions.
Turning the page a year after the chaotic climate summit in Copenhagen, more than 190 countries meeting in Cancún kept ambitions in check and made headway on sticking points instead of seeking a wide-ranging treaty.
