It's also not clear what zero emissions mean. Is the supply chain zero emissions?

It's not clear what "zero-emissions" should mean, but in the context of California environmental regulations it refers specifically to vehicles that don't emit any pollutants from their onboard power source, e.g. electric or fuel-cell cars.

I'm not sure why your comment is getting downvoted. I also had the same question.

FWIW, I think no one is proposing to apply a requirement of an end item decarbonization to the entire logistics chain behind a product. Most proposals want to apply regulation to many individual links up and down the chain directly.

I downvoted because it is very clear and if you want other people to answer a question you have to put in some work. I don't care to see trivial questions so I downvoted and banned that guy from my view.

I actually thought it was a rhetorical question, with the intent of stating that the law still wouldn't save us from supply chain emissions.

Thank you for explaining that to me. I think I will continue filtering out that person for stating banalities.

Thank you. We need to think about these things because if we are just satisfied with "no emissions from the tailpipe" we are doomed. Buying a Tesla is not buying an fossil fuel free product. Teslas require fossil fuels to make and the more Teslas we buy, the more fossil fuels we emit.
