The only carbon capture/sequestration method I’m aware of without significant tradeoffs outside of price is direct air capture, and last I saw, that clocked in at $600-1200/ton (Climeworks). So maybe not such a terrible deal?

Wetlands do a better job of carbon sequestration than trees.

Globally, we've lost 85 percent of our wetlands since the 1700s.

Maybe we should restore them.

The startups in this space were targeting $100/ton before the recent inflation hit.

It turns out if you divide the $/ton by 100, you get $/gallon of gas equivalent.

Burning a gallon of gas emits 20 lbs of CO2 (most of the weight is in the oxygen), and a ton is 2000 lbs.

Anyway, at $6-12 dollars per gallon of gasoline, direct air capture is clearly much worse than just not burning oil. At $1-2, it’s less than the current gasoline taxes in the US.
