Clean Air Day 2024

On the first Wednesday of each October, the Coalition for Clean Air hosts California Clean Air Day to reduce air pollution. The statewide annual event is built on the idea that shared experiences unite people to take action and create new habits to improve air quality.

This year, join in celebrating California's Clean Air Day on Wednesday, October 2nd. Take the individual pledge to challenge yourself to take the actions we know are essential to clean air, like taking transit, shopping local, installing an air monitor and much more. Take the organizational pledge to have your employer or school publicly show their support for clean air.

Air pollution in California poses serious health risks, and transportation remains the largest source of pollution. You can help clear the air by pledging to support Clean Air Day and choosing sustainable commuting options like biking, walking, carpooling, or using public transit.

Don’t miss this opportunity to make a positive impact and contribute to a cleaner, greener future!
