Automakers must improve their mileage every year, up to a fleet-wide average of 54.5 mpg in 14 years. Green groups praise the new regulations, while opponents call them job-killers.

The White House and automakers are expected to formally announce Friday a new agreement to raise auto mileage standards annually until they reach 54.5 miles per gallon by 2025, according to groups briefed on details of the changes.
In April, automakers and the Obama administration finalized the first increases in vehicle fuel economy standards in two decades – a rule that hiked fleet mileage to 35.5 miles per gallon by 2015. The next month, they agreed, in principle, to take the next step. That rule – expected to be finalized a year from now – would set standards to apply to vehicles built between 2016 and 2025.
Officials at the Alliance of Automobile Manufacturers were not commenting on the deal. Environmentalists briefed today on the deal outlines were cautiously optimistic.
"What we're hearing today sounds like a very positive development," says Michelle Robinson, clean vehicles program director for the Union of Concerned Scientists in Washington. "We think the technology exists to save even more fuel and reduce pollution. But overall, we're pleased at the direction this is taking."
