The EPA and National Highway Safety Administration (NHTSA) today announced its final rule establishing federal regulations creating greenhouse gas emissions and fuel economy standards for new cars and trucks. The regulations will apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, covering model years 2012 through 2016.

The new regulations require these automobiles to meet an estimated combined average emissions level of 250 grams of CO2 per mile, equivalent to 35.5 miles per gallon.

Automobile manufacturers support the regulations because they allow manufacturers to build a single national fleet that satisfies requirements under both federal regulations and California’s low emission vehicle standards (along with those states that have adopted California’s standards).
