The Environmental Protection Agency is being spurred by the U.S. Supreme Court to revamp its regulatory policies regarding greenhouse gas emissions from cars—a major concern in the debate over global warming, and one that the agency had previously reserved the right to ignore.

The Supreme Court ordered the federal government on Monday to take a fresh look at regulating carbon dioxide emissions from cars, a rebuke to Bush administration policy on global warming.
In a 5-4 decision, the court said the Clean Air Act gives the Environmental Protection Agency the authority to regulate emissions of carbon dioxide and other greenhouse gases from cars.
Greenhouse gases are air pollutants under the landmark environmental law, Justice John Paul Stevens said in his majority opinion.
