"If adopted, the plan would have the effect of compelling the industry to make the cars, sport utility vehicles and other vehicles it sells in California much more fuel efficient. Unlike the particles and gases that contribute to air pollution and smog, whose emissions can be reduced technologically, the gases linked to global warming are an inevitable product of fuel combustion, and no way yet exists to filter them from engine exhaust. The only way to comply with the proposed rules would be to build vehicles that burn less fuel."
