Even then it might not change the vehicle factory much, as it moves from a high $ capital cost, to a high environmental capital cost that you will want to spread over as many vehicles as possible. The easiest thing to reduce capital costs would be to stop painting vehicles and switch to stainless steel skins as paint is one of the single largest capital expenses in building a car. Downstream suppliers of the plant might change, mainly ones that have a high energy, low capital(either $ or environmental) process.
