States sue EPA over global warming

BOSTON, MA The high court decided a year ago that carbon dioxide and other greenhouse gases are air pollutants under the Clean Air Act and ordered the Environmental Protection Agency to take action.

But 16 states and others say in a court filing Wednesday that the EPA has not issued a decision on regulation. Their court filing seeks to compel the EPA to act within 60 days.

An EPA spokesman has not responded to a call seeking comment.
