What Does "Clean" Mean?

What does it mean to buy a "clean" car? These days it means choosing from hundreds of vehicle makes and models that offer better efficiency and reduced impact on smog and global warming. With more than 50% of California's total smog pollution and 38% greenhouse gas pollution coming from motor vehicles - your car selection can make a significant difference on your impact to smog, global warming and energy security.

The Fuel Economy and Environment Label makes it easy to find the cleanest car for your family, and it's posted right on the window of every vehicle. This label gives each car two ratings from 1 (worst) to 10 (best) for smog and greenhouse gas emissions.

The higher the Greenhouse Gas Rating the less fuel you're burning - which means fewer greenhouse gas emissions. The higher the Smog Rating the less you’ll be contributing to smog in the air. So, before you hit the lot, visting our Vehicle Search section to compare ratings for the vehicles you are considering.

Think clean and buy cars with higher ratings.
