In 1975, after the oil embargo, Congress approved the most successful energy-saving measure this country has ever seen: the Corporate Average Fuel Economy system, known as CAFE, which set minimum mileage standards for cars. Within 10 years, automobile efficiency had virtually doubled, to 27.5 miles per gallon in 1985 from just over 14 miles per gallon in 1976.
The mileage standards are still 27.5 m.p.g. Except for minor tweaks, Congress has refused to raise fuel efficiency requirements or close a gaping loophole that lets S.U.V.’s and pickups be measured by a more lenient standard.
Americans who heard President Bush’s State of the Union address, including his pledge to reduce America’s gasoline consumption, can be forgiven for thinking he was finally ready to change that. But all Mr. Bush really asked for was the authority to set mileage standards in a different way. Rather than requiring companies to meet an average fuel-efficiency standard, balancing gas savers against gas guzzlers, he would assign targets model by model, based on factors like size and weight.
As for what those new targets might be, Mr. Bush would leave it to his secretary of transportation to decide. And he asked the country to take it on faith that this new measurement system, combined with technological advances, would lead to annual mileage improvements of 4 percent a year.
