The Biden administration is reviewing California’s plan to ban the sale of new gasoline-powered cars by 2035.
To get federal approval, California claims it “needs” this ban to prevent harm to public health from particulate matter—airborne particles like dust, dirt and soot.
But banning gasoline cars would do little to reduce particulate emissions, and it could even increase them.
That’s because new gasoline cars are very clean.
According to the Environmental Protection Agency, cars emit only about 1% of all direct fine particulate matter in California, and most of those emissions come from older models.
The newer gasoline cars that California wants to ban will often have particulate filters that reduce emissions to below one 1/1,000th of a gram per mile driven.
The main source of car emissions used to come from the tailpipe.
Today most vehicle-related particulate matter comes from tire wear.
California calls electric cars “zero emissions vehicles” because they don’t have tailpipes. That is deceptive.
Generating the electricity that powers those cars creates particulate pollution, and of course electric cars still use tires, which are made from petroleum.
