Environmental Performance Label

This page last reviewed November 20, 2012


Background

Beginning in the 1998 model year, the Smog Index Label began appearing on all new cars sold in California.  The label was intended to help consumers compare the smog forming emissions from different vehicles within that model year. Assembly Bill 1229 (Nation) signed into law in 2005 required the ARB to redesign the Smog Index Label to include information about emissions of global warming emissions. To meet this requirement, cars manufactured after January 1, 2009 were requied to affix the Environmental Performance (EP) Labe. This label provided both a Smog Score and a Global Warming Score, both from 1 to 10, with 10 being cleanest and 5 being the average vehicle.

In 2011, The U.S. Environmental Protection Agency and the U.S. Department of Transportation have adopted a new Fuel Economy and Environment Label that is required on all vehicles beginning in model year 2013.  In order to harmonize with the Federal labeling program, this new label is replacing the California Environmental Performance Label on most new cars sold here. www.DriveClean.ca.gov provides these ratings so that you can compare cars that you are looking to purchase.
