EPA Proposes 62-mpg Fuel-Efficiency Standard by 2025
1 October 2010 4:32 pm
The U.S. Environmental Protection Agency has proposed fuel economy and greenhouse gas emissions standards that could require cars and light trucks to get as much as 62 miles per gallon of gasoline by 2025. The proposed rules would not be finalized for 2 years and would not take effect until 2017. Some perspective from the nonprofit Center for Biological Diversity:
The most ambitious of today's proposals would increase fuel efficiency by 6% a year, which would mean U.S. fuel efficiency would be approximately 37 miles per gallon for new cars and light trucks in 2017. By comparison, Europe and Japan reached 42 mpg in 2008. The United States could reach 62 mpg in 2025 (again, under the most aggressive option), but Europe has set a more ambitious target of 64.8 mpg by 2020—5 years earlier.
Automobile manufacturers are ambivalent about the proposal.
