Climate yes, but air quality not by as much as you'd think. Multiple studies have come out showing that the weight of EVs puts more pressure on tires and breaks, which in turn increases the particles they dump in the air.
> As a result, total PM10 emissions from EVs were found to be equal to those of modern ICEVs. 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.
As the quote mentioned, this can be improved. Lighter batteries, better regenerative breaking, and improvements in tire material would all help.
