9th Annual California Clean Air Day

October 7, 2026

Join thousands of Californians taking action for cleaner air

What Is Clean Air Day?

California Clean Air Day is the state’s largest clean air event, organized by the Coalition for Clean Air. Every year, tens of thousands of Californians pledge to take individual actions that reduce air pollution and protect public health. Together, we’re proving that small changes add up to cleaner skies for everyone.
