WASHINGTON -- A divided 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, a normally harmless gas, is a byproduct of burning fuel and is thought to cause global warming.
In the closely watched case, two judges of the U.S. Court of Appeals for the District of Columbia Circuit ruled against regulation, but issued significantly different opinions. One judge on the panel 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.
The lawyers say they don't think the divided opinion will help automakers in their effort to overturn California rules that aim to limit greenhouse gases from cars and trucks. Industry reaction was not immediately available.
