Well I claimed that I’ve not seen a study that accounts for all the different attributes at once. So there’s really nothing for me to provide?

But if you really need it, MIT did a study in 2019 and they explicitly (in about 2 sentences) declare that they don’t take into account battery lifetime, capacity degradation over time, battery efficiency’s sensitivity to cold, the problem with disposing of depleted batteries. According to their study an EV has about 55% of the emissions of a traditional ICE of comparable size, not accounting for the aforementioned details, nor the fact that EVs replace batteries. I.e. they assume one set of batteries for the entire lifespan.

Now, I might very well be wrong. And I probably am (judging from the down vote bombing). But I just want to see a thorough study of both types of vehicles with everything taken into account from basically drawing board to junkyard.
