Industry & Manufacturing
In California, 35 local air pollution control districts directly regulate factories, industrial facilities and other stationary sources of smog-forming and toxic pollution. The local districts issue permits to limit the amount of pollution these facilities create, and are responsible for enforcing operations at the facilities under these permits.
CARB directly regulates the largest contributors to greenhouse gas emissions in California by establishing an overall declining limit of greenhouse gas emissions from industrial sources under its cap-and-trade program. CARB also regulates some materials used in industrial processes, such as industrial cleaning chemicals and abrasive blasting materials.
Local Air Districts
Businesses and other other sources of pollution that are at fixed locations are issued permits by one of 35 local Air Pollution Control Districts. Contact your local air district to learn more.
