The Obama administration will finalize strict new fuel-efficiency vehicle standards Tuesday, requiring the U.S. auto fleet to average 54.5 miles per gallon by 2025, according to individuals briefed on the matter.
The new rules, which expand on existing standards requiring American-made cars and light trucks to average 34.5 mpg by 2016, will significantly cut U.S. oil consumption and greenhouse gas emissions by the time they are fully implemented, the Environmental Protection Agency says. Unlike many energy policies enacted under President Obama, the vehicle standards are a relatively uncontroversial move embraced by industry and environmentalists alike.
