> It’s called Carbon Coin in the book, a Bitcoin-like currency that the Ministry gives out for carbon sequestration — that is, any project that sucks CO2 out of the air, whether it’s carbon capture or farmers rewilding their fields — at a rate of one coin to one ton. Oil companies get coins if they stop being oil companies, basically, leaving their assets in the ground for a century or so. Coins can then be bought and sold on currency exchanges like any other.

The planet-saving coin thus becomes the safest investment in history, even more so than U.S. Treasury bonds. Our entire economic system becomes as motivated to fight climate change as it is currently motivated to ignore it.
