Our mission

The Yolo-Solano Air Quality Management District is committed to protecting public health and property from the harmful effects of air pollution. We believe everyone has the right to breathe clean air regardless of where they live or work.

As a part of the local community, we collaborate with businesses to find practical solutions that meet their needs while upholding our air quality standards. With deep roots in agriculture, we also work closely with the agricultural community on programs that reduce emissions while preserving working lands.
