Power to Take Action

Does the Environmental Protection Agency (EPA) have the power to regulate pollution from cars, which contributes to global warming? The U.S. Supreme Court says yes. The court's April 2 decision urges the EPA to take action, and adds that the agency cannot avoid its responsibility.

Vehicles spew carbon dioxide when they burn fossil fuels, such as oil and gasoline. Scientists have evidence that the heat-trapping gas adds to global warming.

Lawyers for the EPA had argued that an existing law called the Clean Air Act did not give it the authority to enforce rules about vehicles' carbon dioxide emissions. Now, environmentalists hope that the EPA will make tougher rules.
