It’s clearer every day: the future of transportation is electric. We should be cheering this transition—and encouraging it, because along with the benefits for drivers, electrifying transportation is going to be a critical piece of fighting climate change.

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.

I’ll be at the LA Auto Show this week to check out the latest EVs and efficient cars from automakers from around the world, and to see what carmakers are saying about their future plans. The LA Auto Show is traditionally focused on new technology, and this year should bring more news and debuts of cleaner cars. I’ll also be listening for how the automakers present their lineups and future plans and am especially interested in hearing how the industry squares their efforts to rollback vehicle standards with claims of environmental responsibility and future clean models.

General Motors has proposed what it’s calling a “National Zero Emission Vehicle (NZEV) program” that would require automakers to sell a minimum volume of plug-in or fuel cell vehicles in the US. While this may sound like an innovative idea, it could dramatically undercut existing programs in states including California that are showing real leadership in cutting vehicle emissions. The GM proposal calls for a 50-state ZEV sales requirement of “15% credits” by 2025, but that doesn’t mean a 15% sales requirement. In fact, it would be far short of that, at best requiring less than 5 percent ZEV sales in the US by 2025, and potentially much less, while potentially undercutting both state-level electric vehicle requirements and federal greenhouse gas emission standards.

The sales numbers are in for the first half of 2018 and more new car buyers than ever are choosing an electric vehicle (EV). Through June, over 123,000 new EVs were registered in the US, compared to 91,000 in the first half of 2017, an impressive increase of 35 percent. And it’s more than double the sales from just 3 years ago.
