A new study from UC Berkeley confirms what EV fans already know: EV adoption does, in fact, make the air cleaner. Perhaps even more importantly, the study offers some quantifiable, granular data about how much electric vehicles are impacting emission rates in the here and now, not just in the foreseeable future.
