Take the Pledge for Clean Air Day 2025  

California Clean Air Day is back on Wednesday, October 1! Pledge to replace one solo car trip with a sustainable option to reduce your emissions and create new habits to promote healthy air quality.

Get moving for clean air by: 

• Walking, biking, or riding your scooter

• Riding transit for free on Clean Air Day

• Carpooling with family, friends, or coworkers

• Skipping the commute and working from home

Take the pledge for the chance to win an e-bike! Eligible residents of the San Diego region who pledge and check the box to receive communications from trusted partners will be entered into a sweepstakes to win a folding e-bike, powered by Rad Power Bikes.
