Note that the majority of particulate emissions from traffic _aren't_ from the power train. The fact that BEVs are heavier than the vehicles they replace means tyre, brake, and road wear are all worsened. In terms of particulates (and local air pollution), they're a marginal win if they're a win at all. See https://doi.org/10.1016/j.atmosenv.2016.03.017 https://doi.org/10.1016/j.atmosenv.2016.03.017
