In New Zealand we have a pretty effective system that covers all fossil fuel use nationally, as well as several other greenhouse gas emission classes (notably not agricultural emissions though hopefully they’re included soon). The EU has something similar as do several other jurisdictions. It’s a solved problem at scale.

In NZ we also have an effective system for recognising and incentivising certain classes of forest carbon removals (which I think are a legitimate and important class of credits - unlike avoided emission credits which I agree are junk).
