A pair of psychologists and an economist at the University of Turku, in Finland, have found that because the average electric vehicle (EV) owner is wealthier than the average person, they still have a bigger than average carbon footprint.
Maybe EVs are not a comprehensive climate solution??
In other words: OP is barking up the wrong tree as the EVs have little to no correlation with the non-EV-related carbon footprint of the EV owners.
Unless, of course, if OP is implying that EVs are too hard to acquire for the less wealthy consumers, though I somehow doubt that.
