Emissions standards are so low now that particulate from the tires and brakes is a significant fraction of the air pollution. They will wait to tell us that until after we convert to electric.
Anyway a good way to reduce air pollution is to have good used cars cheap to buy and cheap to maintain. If you haven't seen ReasonTV's "Great Moments in Unintended Consequences" about Cash for Clunkers, check it out. The whole series is hilarious.
