"The White House is poised to order all federal agencies to evaluate any major actions they take, such as building highways or logging national forests, to determine how they would contribute to and be affected by climate change, a step long sought by environmentalists.

Environmentalists say the move would provide new incentives for the government to minimize the heat-trapping gas emissions scientists blame for global warming. Republicans have opposed it as potentially inhibiting economic growth.

The new order would expand the scope of the National Environmental Policy Act, or NEPA, a landmark statute that turns 40 today. The act already requires federal agencies to consider environmental impacts such as land use, species health and air and water quality when approving projects."
