Clean Air Day 2026: Thank You
The Coalition for Clean Air hosts California Clean Air Day every year on the first Wednesday in October. SANDAG celebrates Clean Air Day by encouraging the San Diego region to get moving and take the pledge to walk, bike, carpool, or ride transit on Clean Air Day.
In 2026, we collected 1,773 pledges in the San Diego region. Thank you to every individual, organization, and student who took action for clean air.
