In about turn, Bush signs climate change bill 

President George Bush, after years of holding out against proposals to combat climate change, yesterday signed into law an energy bill establishing higher fuel-economy standards for new cars and other conservation measures. 

Bush described the bill as 'a major step toward energy independence and easing global warming'.

The White House claimed itwent part of the way to fulfilling promises made at the environmental conference in Bali last week. 

The legislation, though limited in scope, represents the biggest fuel efficiency push by the US since the 1970s oil crisis.
