Welcome!  Project Clean Air celebrates 20 years of improving air quality for our health and to see the mountains.

Project Clean Air volunteers have been working to improve air quality in the San Joaquin Valley of California since 1990.  The agency received its 501(c)3 nonprofit designation on July 11, 1991.

Our award-winning programs have existed in classrooms, agricultural operations, fleet vehicle operations, car crushing yards, and at community events.

Project Clean Air has a chapter in San Luis Obispo, which serves as the Central Coast Clean Cities Coalition (C5).  The agency also hosts the San Joaquin Valley Clean Cities Coalition.

A visit to this website will provide you with tips for improving air quality.  As much as 80% of the air pollution in the Central Valley comes from motor vehicles.  So, you will find a lot of information and resources about clean transportation options, including vehicle maintenance, electric vehicles, alternate fuels, public transit, and resource pages to help you carpool, ride your bike, telecommute, or take a hike!  You will also see stories about fleet operators, communities, and individuals working together to clean the air.
