Split Supreme Court Orders EPA to Act on Greenhouse Gases

WASHINGTON (Fox News) — The Supreme Court rebuked the Bush administration Monday for its inaction on global warming in a decision that could lead to more fuel-efficient cars as early as next year.

The court, in a 5-4 ruling in its first case on climate change, declared that carbon dioxide and other greenhouse gases are air pollutants under the Clean Air Act.

The Environmental Protection Agency has the authority to regulate those emissions from new cars and trucks under the landmark environment law, and the "laundry list" of reasons it has given for declining to do so are insufficient, the court said.
