US President George W Bush has announced a series of multi-million pound studies and initiatives aimed at reducing the impact of heat-trapping gases on the globe.
The package, including an £84 million NASA research project on climate modelling, was unveiled in a written statement less than a week before Mr Bush embarks on his second European trip.
Allies of the US have criticised Mr Bush for abandoning the 1997 Kyoto treaty which would put limits on the emissions of gases that many scientists say are warming the globe.
Mr Bush has promised European allies that he would help devise an alternative to the Kyoto treaty that would ease global warming without hurting the US and other economies.
He said, in a statement: "These initiatives represent important steps in putting our principals to work through partnerships with other nations, industry and non-government organisations."
The US government and a host of energy companies have agreed to develop new technologies for reducing the cost of capturing carbon dioxide from fossil fuel combustion plants.
The Department of Treasury entered into a £10 million "debt for forest" agreement to help El Salvador conserve its rain forests.
