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 the 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.
The court’s four conservative justices — Chief Justice John Roberts and Justices Samuel Alito, Antonin Scalia and Clarence Thomas — dissented.
Kennedy, swung left on this one! I stand by my original asseesment, just regulating cars using the clean air act is inadequate, but the important matter resolved here is that CO2 is a pollutant, and this will, I hope, provide precedent in cases to come.
