EVs emit nothing. Cars do not get much cleaner than that. There’s been a load of obfuscation out there about the source of electricity however, and it seems never a day goes by without a commenter writing something about “dirty coal” under articles about EVs.

Fact: EVs are still cleaner than most cars, even if powered by a straight coal-powered grid, which is typically not the case. If it were the case, a Leaf powered by pure coal-generated electricity would equal the emissions of a 30 mpg car, and the U.S. average for gas cars is 26 mpg.

But most grids have multiple sources, and all are getting cleaner. As gas cars age however, their emissions tend to go up, so EVs are recommended by numerous science-citing advocates.

They and their electricity sources add up to a proposition that is clean and getting cleaner.
