Innas B.V appears to be the same consulting firm where the first author works.

Reading the paper full-text, you see a lot of policy recommendations and one wonders what the standing of the authors is for full-on policy recommendations, based on the very limited data in the paper.

Namely, the analysis is really just using vehicle weight as a scale factor on a primitive PM2.5/PM10 "emissions/kg" relationship. Re-suspension of road dust dominates these particulates (in their model, anyway), and EVs and ICVs both do this, so any PM reductions by EVs are dominated by road dust kicked up by their larger weight.

And here's a non-review that examines ozone emissions, but from a much more serious modeling point of view:
