The U-S auto industry will appeal a federal judge’s ruling in Vermont that said states could regulate greenhouse gas emissions from vehicles.
The Alliance of Automobile Manufacturers argues that federal law prohibits states from regulating fuel economy.
The industry says technology cannot be developed to meet the tough standards pushed by California, Vermont and other states.
Automobile Alliance President Dave McCurdy says greenhouse gas emissions must be dealt with at the national level.
Vermont Attorney General William Sorrell says the appeal was expected. But Sorrell says the court ruling was well reasoned and sound.
