2019 Stats

California Clean Air Day is all about people taking action.

An incredible 97% of pledgers reported following through on their pledge to plant something, reduce your vehicle emissions, and/or switch something out. The campaign is also about community. Thanks to the support of our sponsors a new microgrant program and event calendar helped facilitate over 90 clean air day events around clean air. Finally, its about collective action. With the help of more than 300 organization partners, we reached critical mass – 650,000 individuals across the State committing to take action to reduce air pollution.

We’re excited to build more momentum as we approach California Clean Air Day 2020 – stay tuned for news and announcements. In the meantime, check out some of our stats from 2019 below!
