2009 California auto emissions labeling mandate

California cars will be required to exhibit greenhouse gas emission labels in 2009.

In February, the California Air Resources Board will hash out the label's details. The 2005 implementation law requires all new California cars and trucks, beginning in 2009 to carry a prominent label listing a Global Warming Index rating.

The label must compare "the emissions of global warming gases from the vehicle with the average projected emissions of global warming gases from all vehicles of the same model year," according to the law. The label must also contrast a car's greenhouse gas emissions with the vehicle that model year that contributes the least to global warming.
