The Air District’s mission is to protect public health, air quality and the global climate.

To achieve its vision of a healthy breathing environment for every Bay Area resident, the Air District employs a multifaceted approach to air quality management. 

The Air District places a strong emphasis on public education. The actions of individual citizens can make a substantial impact on air quality.

Spare The AirThe Spare the Air program is one way the Air District provides important information to the public regarding air quality in their communities and actions individual citizens can take to reduce air pollution.

The Air District staff will be on-hand at the Pacific Coast Dream Machines Show, April 30 from 10 am to 4 pm at Half Moon Bay Airport, encouraging people to sign up to receive Spare the Air email alerts and providing informational materials about the program.
