Thanks Oil4AsphaultOnly.You have to remember that BEV's are heavier than ICE, which means there's literally more material in them. The UCLA study compared a 3900lb Nissan Leaf with a 2800lb Nissan Sentra. That's 900lbs of additional material. And most of that weight isn't the highly recycled (aka less energy intensive) aluminium nor steel. Even the model 3 (despite all the optimizations and aluminium) is still a few hundred pounds heavier than a comparable sports sedan.
As more batteries are made at their place-of-use, then their carbon footprint will be lowered. And as battery density improves, then so will the carbon footprint. Once there are enough batteries in circulation that recycled batteries are viable, then it should seal the case that BEVs take less CO2 to build.
Good chat - appreciate the angle you presented. !
