U.S. to limit greenhouse gas emissions from autos

The Obama administration plans to announce on Tuesday that it will set national restrictions on greenhouse gas emissions from automobiles, in what environmentalists are hailing as a major step to curb global warming and spur development of more fuel-efficient cars.

The national policy will mimic, with slight modifications, a California policy that state officials fought the Bush administration for years to implement, two sources with knowledge of the agreement said.

California officials have signed on to the policy, one of the sources said. So have major U.S. automakers.
