It’s certainly a good question. They may have done that analysis themselves, but I haven’t seen it.

And yes it’s about $20,000 USD per year to account for the average american’s emissions. I’m actually cheered that this is a good deal less than average GDP per capita. So as the tech scales the costs are at least possible to pay. It would be much worse if the costs exceeded GDP.

Meanwhile, buying a smaller subscription provides funds to help scale the technology which should lower costs. This is Stripe’s goal with Stripe Climate.

On the FAQ page there's an item about this:

> According to them, the grey emissions for the construction, operation and deconstruction of a Climeworks machine are less than 10% of the captured carbon dioxide with the use of waste heat and renewable electricity. Our goal is to reduce this to 4%.

(Apparently this is most practical in Iceland because of the abundant geothermal energy there.)
