Beginning Jan. 1, every 2009 model year and newer car sold in California will be required to carry a label that clearly ranks the vehicle's environmental impact.
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, www.DriveClean.ca.gov, that provides information on the cleanest, most efficient cars on the market.
For an example of the label go to the press release online by clicking here.
