> Downside of CC is it's still too expensive

Some googling suggests that it's $200 per metric ton, is that right?

That would put the cost of capturing the world's entire footprint at $7T per year. That's a lot of money but seems pretty close to worth doing. Especially given that once we decide to do it, it will get cheaper quickly.

When I was involved in this, the real cost of capture, all things considered, was in the high thousands/ton. Climeworks, which is one of the companies trying to take this to a big scale, quotes it at 1,000EUR/ton. No one really talks about "carbon emitted while capturing carbon", though, as that would make the numbers MUCH worse.

So, I don't think $200/ton is feasible now. Even if that were the price, 7T/year is like 10% the GDP of the whole world. That means everyone, literally everybody in the planet, people and corps., have to put aside 10% of their income for this to happen. Impossible. I was selling 10k/year commitments to companies making hundreds of millions/year and they were like "nah, we'll think about it".

Sure, if you are spending other people's money, it's cheap. Pretty sure that once you commit to spending $7T per year the amount of fraud will increase dramatically.
