In terms of emissions the EV are definitely better than any combustion cars. Creating the pollution only in several easy to control sources (power plant) and some renewable ones is way better than delivering it directly in the city streets by devices (cars) with questionable technical state of their catalysts/particle filters/AD blue injectors which moreover most of the time spend standing in traffic jams or on the traffic lights. Moreover large part of such drives is made with cold engines, i.e. absolutely not in ideal conditions (especially diesel cars in the cities).

The problem is the feasibility of the electrification. It works best with electric trains, trams or trolleybuses but using trolleys is impossible for common traffic where everyone goes where he wants, when he wants and how he wants.
