Just a glance but I didn't see it mention things like fluids in ICE cars-oil, transmission fluid, radiator and the carbon footprint for those.

I will be interested to see as Lead batteries start to be used in place of Lithium Ion, will that change the carbon footprint.

Personally, I don't drive an EV for the carbon footprint but I do think making the production of the car and energy, in general, more environmentally friendly is a noble goal and studies like this may help with that.
