Arbitrage it from places where green energy is cheap or free. For example, iceland has pretty much 100% renewable energy sources. Already it has an extensive aluminum industry because energy there is cheap, and aluminum is energy-intensive to use it.

So, in theory, if you use green energy to produce a carbon-offset product, it's still a useful product.

The aluminum smelter in iceland is a former ALCOA smelter from Rockdale TX. They ship the ore in from outside.

Let's not pretend mining bauxite ore is 100% renewable.

Maybe, you now have to produce that aluminum somewhere else.
