The Coalition for Clean Air (CCA) is a statewide organization exclusively dedicated to protecting public health, improving air quality, and preventing climate change. As California’s only statewide organization focused solely on air and climate protection, CCA empowers policymakers, businesses, and individuals to make informed decisions for cleaner air.

Our priorities include reducing pollution from California’s freight industry, directing climate investments to benefit the most polluted communities, and promoting clean air technologies.

Since 1971, CCA has led groundbreaking initiatives to reduce pollution by supporting policies and funding programs that cleaned up bus fleets, heavy-duty trucks, and passenger vehicles, securing diesel emission reductions at the San Pedro Bay ports, and helping pass a series of landmark climate change laws in California.

Recent victories include playing a pivotal role in the creation of California’s Clean Truck Check program, which requires pollution control equipment on heavy-duty trucks to be operating properly.
