I'm all for EVs, but half of PM10 pollution is independent of engine type as it comes from brake and tire wear: http://publications.jrc.ec.europa.eu/repository/bitstream/JR...

So direct environment impact is still huge for EVs and calling them ZEV is literally a scam.

Don't EVs use resistive breaking to recharge their batteries? I would hope that reduces particle emissions.

Though I suppose that EVs and hybrids are heavier than similar gas powered counterparts, so tire wear is worse. At least until EVs can be made lighter.

You mean we can do something today that will reduce PM10 pollution by half?!

That’s fantastic news!

    We could. We could massively fund public transit and massively reduce private car ownership. But we won't, because then capitalists will make less money.

scam is a bit of hyperbole. also, ZEV has always explicitly referenced tailpipe emissions, which is also why there's been the odd sounding "partial zero emissions vehicle" category. It's certainly valid to be concerned about additional sources of fine particles, but eliminating engine emissions is not something to be dismissed as a scam.

Further, particle emission from brake dust is mitigated in EV's that use regen braking. One of my ev's can go days without phycical brake usage, and another uses the brake pads so infrequently it has an automatic mode to touch the discs occasionally just to keep them from building up rust.

tire particles --- different compounds can effect that, but will always be a side effect of tires on vehicles.

    There's vehicles like trains, subways and bycicles, responsible for transporting hundreds of at least a billion people per day, which don't use tires whose particles are the biggest source of microplastics.
