SACRAMENTO – Beginning Jan. 1, every 2009 model year and newer car built for sale in California will be required to carry a label that clearly ranks the vehicle's environmental impact.

The label will show the simple ranking system that provides consumers practical information that can help them choose the most environmentally friendly vehicle that still meets their transportation needs.

"This label will arm consumers with the information they need to choose a vehicle that saves gas, reduces greenhouse gas emissions and helps fight smog all at once," said ARB Chairman Mary Nichols. "Consumer choice is an especially powerful tool in our fight against climate change."

The environmental performance label will have two scores on a scale of 1-10, a Smog Score and a Global Warming Score. The average new car will score five on both scales. The higher the score the more environmentally friendly the car is . The California Air Resources Board also hosts a consumer web site, DriveClean.ca.gov, that provides information on the cleanest, most efficient cars on the market.
