Actually, electric vehicle lifetime environmental costs from all aspects, that is from construction through use and finally recycling, is about one half of that of an ICE vehicle. This is according to a study from Argonne National laboratory.
I'd have to look to find it again, but the figure I was quoting was from a pro-environmentalist source, and corroborates a lot of info I've seen about the issue anyway.
I agree, over their whole life time, a EV will be less environmentally damaging, but we are talking at least 20 years or so to see the benefits, during which time localities have been wrecked by lithium mining, and children killed my 'artisanal' cobalt mining. And I haven't seen a discussion of how we scrap them at the end of their lifespan.
I've yet to be convinced the problems of EVs are worth the benefits, especially considering the slowness of the move to 'green' energy means we just move the emissions from the car itself to a powerplant somewhere else, and outsource the pollution of manufacturing to developing countries whom we then lecture for the damage they are doing.
The only real argument in favour of an EV, in my opinion, is cleaner city air, but I suspect all the money being spent would be better invested in 'cleaner' ICE cars.
