Coalition for Clean Air

The Coalition for Clean Air was founded in 1971, at a time when clean air in California seemed almost unimaginable. Since then, we’ve come far and won many significant victories. From spearheading California’s original Smog Check program in 1981 – which continues to reduce 100 tons of automobile pollution every day – to helping pass California’s landmark global warming legislation, we have helped position California as a world leader in strategies to reduce air pollution.
