On September 15, the U.S. Environmental Protection Agency (EPA) and U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) jointly announced a proposal to establish national standards for greenhouse gas (GHG) emissions and Corporate Average Fuel Economy (CAFE). The standards would apply to model year 2012 – 2016 passenger cars and light trucks and are based on the vehicle footprint, which is related to the vehicle size. Thus, the standards for vehicles with a large footprint would be different than for a vehicle with a smaller footprint.

The proposal and information about how to submit comments on the proposed standards can be found on both EPA and NHTSA websites.

Projected Emissions Compliance Levels under the Proposed Carbon Dioxide Standards for Passenger Cars and Light Trucks
Graph showing the projected emission compliance levels (grams per mile) under the proposed carbon dioxide standards for passenger cars, light trucks, and combined cars and light trucks for model years, 2012, 2013, 2014, 2015, and 2016. For more detailed information, see the table below.
Projected Fuel Economy Levels under the Proposed Standards for Passenger Cars and Light Trucks Combined
Graph showing the projected fuel economy levels (miles per gallon) for passenger cars and light trucks combined for the model years 2012, 2013, 2014, 2015, and 2016. For more detailed information, see the table below.

Note: Greenhouse gases other than carbon dioxide are dealt with separately in the proposed rules.
