The leaders of the world's richest nations have agreed to a compromise deal on tackling climate change.
The British Prime Minister, Tony Blair, has welcomed the deal to cut greenhouse gases.
The German Chancellor, Angela Merkel, has said the G8 summit had agreed that CO2 emissions must first be stopped and then followed by substantial reductions.
Leaders have also agreed to hold talks on a replacement to the Kyoto Protocol within a United Nations framework.

However, the United States has resisted calls for targets to be fixed.
Earlier, US President George W Bush said he hopes developing countries such as China and India can work with his country to bring about climate change.
He said the US had made strong commitments to reduce petrol use by 20% over the next ten years.
