This would be an interesting approach! Not sure how it would work in practice, but it's a fun thought...

And there could be inherent value there, especially as a carbon capture tax credit. Instead of proof of work or proof of state, it's proof of capture. You'd have to put together some kind of distributed capture hardware, but... That's maybe possible with current tech?

Unfortunately the fact that it has a clearly measurable value means it's price is pegged to that value.

If this token gets you $100 worth of carbon emissions, it's hard to justify a price higher than $100. If the token gets you absolutely nothing, then the value is absolutely arbitrary - enabling spectacular rise

What if you tied it to a desktop carbon capture device (understood that these don't really exist currently)? Doesn't even have to be particularly efficient, nor tied to carbon credits.
