US President George W Bush said today he would urge major industrialised nations at a summit next week to join a new global framework for fighting climate change after the Kyoto Protocol lapses.

"The United States will work with other nations to establish a new framework on greenhouse gas emissions for when the Kyoto Protocol expires in 2012," he said in a speech laying out his agenda for the June 6-8 G8 summit in Germany.

Bush, weighed down by the Iraq war and facing European criticisms over the US approach to global warming, also urged rich countries to eliminate barriers poor countries face to getting new environment-friendly technologies by 2008.

"If you're truly committed to helping the environment, nations need to get rid of their tariffs, need to get rid of those barriers that prevent new technologies from coming into their countries," he said.

Bush's initiative may deepen a dispute with Germany, the current G8 president, which seeks a strong resolution on fighting climate change at the summit and which wants to bring as many nations as possible to the table.
