We import very little Al from China; it turns out mostly to come from the UAE, which will have absolutely terrible CO2 emissions, as well as greener countries like Iceland and Norway.

It looks like we need to invest in local recycling (which, yes, needs cheap energy, but not as much as primary Al) in order to make more of a circular economy rather than just exporting vast volumes of scrap.
