The San Diego region is well-known for its beautiful beaches and great weather, but what most don’t realize is that the region’s air pollution has been getting worse over the past few years, mainly as a result of increasing emissions from the transportation sector. San Diegans travel more vehicle miles annually per commuter than the state average and other major urban counties. More hours spent in traffic means more air pollutants and greenhouse gases being emitted from those vehicles. Additionally, according to the American Lung Association’s 2021 “State of the Air” report, the San Diego region is the 7th area in the nation with the most ozone pollution.

On Clean Air Day San Diegans can come together as a community to take action to clean up our air and reduce pollution!
