Wildfires
California is currently in its wildfire season. The Air District monitors general air quality in the Bay Area and will issue a health advisory if wildfire smoke appears to be causing elevated levels of particulate pollution in the region. There is currently no health advisory in effect. Residents should take precautions if they are experiencing localized effects of wildfire smoke. For general smoke and fire information, see our wildfire safety tips and CAPCOA’s information and resources.
Spare the Air Program
The Spare the Air Program was established by the
Bay Area Air Quality Management District to educate people
about air pollution, and to encourage them to change their behavior
to prevent it.
During the summer months ground-level ozone is the pollutant of concern. Ozone is formed when pollutants combine on hot summer days, and it accumulates when there is little wind.
In order to protect public health, the Air District issues Spare the Air advisories on days when air quality is forecast to be unhealthy due to high ozone levels. People who are especially sensitive to pollution are advised to limit their time outdoors, particularly in the afternoon hours. These advisories are posted on our web site, recorded on our 1 (800) HELP AIR forecast phone line, announced in local newspapers, and broadcast on local TV and radio stations.
On Spare the Air Days, we ask Bay Area residents to reduce pollution by making clean air choices every day. These simple actions include driving less, taking public transportation, trip-linking, walking, biking, choosing non-gasoline-powered lawn and garden equipment, and avoiding polluting household products.
On this site you will find answers to frequently
asked questions about air pollution, descriptions of its health
effects, information about how various communities and employers
are working to prevent pollution, clean air tips, and a variety
of other educational resources.
In addition, the air quality forecast allows
you to keep track of air quality conditions in your region of
the Bay Area.

Wood Smoke Rebate Program
The Wood Smoke Rebate Program is now closed. We want to thank Bay Area residents for their commitment to improving air quality. In the event that funding becomes available for another round of rebates, we will post information on the page linked above.
