California consumers would pay several hundred dollars more for every vehicle they buy under regulations proposed Monday to cut greenhouse gas emissions.
Proponents hope the regulations will decrease those emissions by nearly 30 percent over the next decade and force similar steps across the nation.
The California Air Resources Board´s staff estimated today that the average cost of meeting the first phase of the new requirements would add 241 dollars to the cost of a light-duty passenger cars.
It would add 326 dollars to the sticker price of a large pickup or sport utility vehicle.
Automakers have promised to sue over standards they say should be set only by the federal government.
