Inspired by Kim Stanley Robinson's novel "The Ministry for the Future". In it, carbon capture is incentived by a blockchain currency that is awarded for removing carbon capture. This currency was managed and awarded by the UN.

This market resolves Yes if a coin is implemented and guaranteed by an international or state governance by 2040, and the coin garners over ten billion USD (or the equivalent) in investment. While the UN is the obvious international governance, I will also consider agreements made by international bodies such as the OECD or the African Union.

There is still a potential for a coin to be implemented for the purposes of "greenwashing". I can imagine a petrostate creating such a coin that has dubious ties to actual carbon removal. As such, for this market to resolve Yes, I will need to be able to find several credible, third party sources that indicate the coin's minting is indeed tied to carbon removal.
