New fuel efficiency standards: Too much or not enough?

tailpipe greenhouse gas emissions pollutionThe Obama administration unveiled a plan to boost fuel efficiency standards for cars and trucks to an average of 35.5 miles per gallon by 2016—four years ahead of current schedule and up from an average of just 25 miles per gallon today.

The new standards (pdf) will also impose—for the first time ever—a limit on greenhouse gas emissions from vehicles at 250 grams per mile in 2016 under the new proposed rule. (That’s about 5.5 ounces per kilometer, for those of you who like your units mixed differently.)

There are very few vehicles capable of meeting the new standards today, which would mean more hybrids and possibly even electric or other alternative vehicles would have to hit the road within seven years for automakers to comply.

Accelerating an energy transformation in the auto industry

CAMBRIDGE, MASS.—By 2030, the people of the world will be driving as many as two billion cars—up from 700 million today—according to John Viera, director of sustainable business strategies for Ford Motor Company. Whether those cars are plug-in hybrids, hydrogen fuel cell vehicles or just supremely efficient internal combustion engines, the economic, environmental and social impacts will be huge—from lithium mining in Bolivia to road rage in China.
