trucks at enforcement stop


Effective enforcement of our regulations is a key element of California’s success in reducing air pollution and fighting climate change. Fair and consistent enforcement also provides a level-playing field for all regulated businesses, ensuring no one has an unfair advantage by not doing their part to help clear the air.
