From the research paper cited by the article:

PM2.5 emissions were only 1-3% lower for EVs compared to modern ICEVs. Therefore, it could be concluded that the increased popularity of electric vehicles will likely not have a great effect on PM levels. Non-exhaust emissions already account for over 90% of PM10 and 85% of PM2.5 emissions from traffic. These proportions will continue to increase as exhaust standards improve and average vehicle weight increases. Future policy should consequently focus on setting standards for non-exhaust emissions and encouraging weight reduction of all vehicles to significantly reduce PM emissions from traffic.

Here's what I find suspicious about this study: resuspension being counted as an emission.

It's said that cars "produce" PMs this way even though they don't per se.

What I'm getting at is that if we reduced the amount of particulates added to the system, then surely there would be less to resuspend?

Unless there's some other, non-car related source of these. If so, why not address it instead?
