Particulate matter is about 60%-20%-20% between engine, brakes and tyres. Electric cars eliminate the emissions from the engine, greatly reduce the brake emissions because of regenerative braking, and slightly increase tyre emissions because of increased weight. And of course Nitrogen dioxide is eliminated by electric cars. Overall you’re taking about a 100% reduction in NO2, and a 70%ish reduction in particulates. One other point also is that tyre particulate emissions vary hugely according to composition and manufacture. So we will need both a switch to electric and proper regulation of tyres, then we’ll really be getting somewhere.
