Eighteen states, led by Massachusetts, filed an unusual legal petition in federal court yesterday to pressure the US Environmental Protection Agency to regulate greenhouse gas emissions from cars and trucks - a move that could lead the automobile industry to produce cleaner-burning cars.

The filing came on the first anniversary of a landmark US Supreme Court ruling that such greenhouse gases are pollutants, and was designed to highlight the lack of progress since then. It also came in the face of suggestions that the White House is stalling approval of a document that would declare these emissions are harmful to public health.
"Once again the EPA has forced our hand, which has resulted in our taking this extraordinary measure to fight the dangers of climate change," Attorney General Martha Coakley of Massachusetts, which is leading the petition, said in a statement. "The EPA's failure to act in the face of these incontestable dangers is a shameful dereliction of duty."
