Ah, I see. That is quite clever. And I like the idea of implementing it in non-centralised market. This could be an actual use case for those, instead of all those pictures of cats and monkeys.
This would have to scale quite significantly for those betting against climate change to be able to affect it. Like you say, corporations could cooperate and also gain some goodwill. And venture capitalists, or just any investor, could chip in.
I really like the idea of creating direct economic incentives for positive development, at the same time as you insure those that are harmed if it doesn't go so well. And this would also be global and have direct effects, and not sensitive to populist politicians and temporary government investments like climate politics tend to be today.
