It's really hard to get good info on it, from trying to find sources previously most tend to hide their funding sources, but the best I've found tend to be that even in the US counties with the dirtiest power generation you're breaking even on carbon footprint after a couple years of average use and given how recyclable the batteries are (we really need to ramp up on how much we're actually doing that though) unless there's a fire even if a car is totalled before it breaks even the bulk of the carbon footprint (the battery) can be recycled at a much lower footprint than the initial mining.
