We have an important opportunity this week to speak up for clean air and climate stability by urging the California Air Resources Board (CARB) to adopt the Advanced Clean Fleets (ACF) rule at its meeting on Thursday and Friday, April 27 and 28. The ACF rule will accelerate a just transition from smog-forming diesel trucks to zero-emisions vehicles. It's vital to protect our air, our climate, and our communities, yet industry lobbyists are pushing back hard. Help ensure that CARB does the right thing: send this email to CARB Chair Liane Randolph today!
