WASHINGTON -- A federal court panel refused on Friday to order the EPA to regulate carbon dioxide emissions from cars and trucks.
In so doing, the three-judge panel sided with the EPA and automakers.
Carbon dioxide is thought to cause global warming.
Two judges of the U.S. Court of Appeals for the District of Columbia Circuit ruled against regulation but issued significantly different opinions. The other judge ruled for regulation.
Lawyers for the states, cities and environmental groups that brought the case say the split ruling will help them in a further appeal, either to the full appeals court or to the U.S. Supreme Court.
