California Air Resources Board

CARB is charged with protecting the public from the harmful effects of air pollution and developing programs and actions to fight climate change. Its mission is to promote and protect public health, welfare, and ecological resources through effective reduction of air pollutants while recognizing and considering effects on the economy. CARB is the lead agency for climate change programs and oversees all air pollution control efforts in California to attain and maintain health-based air quality standards.

In 2010 CARB implemented a regulation to require CA utilities to track and report SF6 emissions
