Air Quality Program

We're protecting, preserving, and enhancing the air quality of Washington.

Air quality affects public health, the environment, and our quality of life. Air pollution causes lung disease, makes existing heart and lung disease worse, and is associated with cancer.

The Air Quality Program's goal is to safeguard public health and the environment by preventing and reducing air pollution. Washington's main sources of air pollution are motor vehicles, outdoor burning, and wood smoke.
