WASHINGTON — The Environmental Protection Agency says another arm of the Bush administration may be low- balling the economic benefits of increasing fuel-economy standards for cars and trucks.
Echoing criticism previously voiced by Democrats and environmentalists, the EPA said in comments filed with the Transportation Department that the department would have been better off using higher estimates for future gasoline prices when it proposed increasing the average fuel economy of all vehicles to 31.6 miles per gallon by 2015.
