San Diego Area

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 2020 “State of the Air” report, the San Diego region is the 6th area in the nation with the most ozone pollution.

On October 7, San Diegans can come together as a community to take action to clean up our air and reduce pollution from cars: more San Diegans driving electric vehicles (EV) and more San Diegans taking public transit (especially zero and near-zero emissions transit!). California Clean Air Day is the perfect opportunity take public transit for the first time or to learn about EVs and maybe even go for a test drive!
