Air Pollution from Vehicles in California: People of Color Bear the Biggest Burden

, Senior vehicles engineer

Cars, trucks, and buses are a significant source of air pollution in California. But how much pollution is attributable to these vehicles and who is exposed to this pollution? To help answer these questions, I’ve used a computer model to estimate the amount of fine particulate matter air pollution (known as PM2.5) created by using on-road vehicles (cars, trucks, and buses). The findings are troubling, both because they show that people of color are exposed to higher levels of harmful air pollution and because this result is likely not to be a surprise to many Californians (full report available in English and Spanish). The study supports the claims many have been making for decades – that on average, African American, Latino, and Asian Californians are exposed to more PM2.5 pollution from cars, trucks, and buses than white Californians. In fact, these groups are exposed to PM2.5 pollution 43, 39, and 21 percent higher, respectively, than white Californians.

California Ready to Take Action on Clean Transportation after Climate Summit

, research and deputy director, Clean Vehicles

With last week’s Global Climate Action Summit in San Francisco all wrapped up, it’s time to get down to the business of turning words into actions.  And next week, California is poised to do just that.  The California Air Resources Board agenda for next Thursday and Friday is chock-full of transformative policies that, if adopted, will accelerate deployment of electric cars and transit buses, increase electric charging and hydrogen refueling infrastructure, bring more low carbon alternatives to diesel and gasoline to the state, and ensure consumers in California and the 12 other states that follow California’s standards continue to have cleaner, more efficient vehicle choices.
