States Sue EPA for 'Foot Dragging' on Warming

States, cities and environmental groups have teamed up to take on the federal government over global warming, the New York Times reports. The 18-state coalition is aiming to force the EPA to take action in the wake of last year's Supreme Court ruling that the agency should limit vehicle emissions if it finds greenhouse gases are endangering public health.

The EPA says it is trying to find a "holistic" solution to tackling greenhouse gases but the coalition accuses it of foot-dragging and wants the agency to release—and act on—its findings on vehicle emissions. "Every day that goes by without a solution, the window of opportunity to fix the problem closes a bit more," says a Massachusetts official. (More Environmental Protection Agency stories.)
