Whether it’s a gas or electric vehicle, cars have quite an impact. In the transition to an electrified world, OEMs are making big promises, not just about the number of EVs they’ll introduce, but also about how those vehicles will be built. The term “carbon neutral” is thrown around quite a bit, and it will be a much cleaner world when that happens.

Earlier this week, carmaker Polestar announced its first partners in its Polestar 0 Project. The carmaker is working with suppliers like SSAB Steel and ZF to ensure that all aspects of a vehicle’s production are climate neutral. It’s an important step and while I’m sure Polestar has the best intentions, they and other carmakers need to follow through on these plans. And as consumers, we need to make sure they live up to the climate commitments they make to us.

A vehicle isn’t built in a vacuum. While automakers build many parts of a car, truck or SUV, most of the stuff that goes into a finished vehicle comes from somewhere else; suppliers are the backbone of the auto industry. Companies like ZF and Bosch may not be household names like Ford or BMW, but without them, vehicles simply wouldn’t be built.

This is actually why there is a shortage of cars right now. Suppliers can’t build their individual parts or they can’t get them to the automakers’ factories fast enough. It’s all an intensely choreographed dance that requires parts to arrive at a factory at a specific time so they can be distributed at exactly the right time. If you ever get the chance to tour a car factory, do it. The timing of getting everything to a worker as they’re attaching it to a vehicle is impressive.
