Not really because a lot of the raw materials sourcing comes from the globalized marketplace still, so there’s still tons of shipping involved. If Mexico produced more raw materials, like fuck, half as much as China, then you might have an argument, but really what’s happening is that an extra hop is being added to the manufacturing process, so more fuel is being burned to deliver the same materials to Mexico so they can be assembled the same as before, then shipped to the next stop. Adding a transit hop from China to Mexico – requires crossing either the Pacific Ocean or the entirety of Eurasia and then the Atlantic – is inherently less efficient than doing the resource extraction and primary processing in the same country. Also, as the article itself points out, one of the main drivers of this trend is literally Chinese companies trying to evade US tariffs. Not actually a win for the environment.
