There is a certain irony in the incessant claims that REDD+ is voluntary and that it is a market (a lemons market, even!). But the facts prove otherwise. REDD+ is a part of an agreement between nation-states: the Paris Agreement.

The people/companies ruled by those nation-states don't get any choice as to whether they participate. If people/companies don't participate, they'll get fined by the nation-state that rules them.

The fact that REDD+ is a lemons market is not a "market failure"; nation-states over-promised and under-delivered. Blaming REDD+'s failure on people/companies not being compliant enough to laws is analagous to blaming PTSD on the battered spouse for not trying hard enough to be nice.

When a promise and actions don't line up, and there is a lot of money involved, the people making the promise are undoubtedly lying about their motives. Treaties like the Paris Agreement are not about saving the environment from fossil fuel. They are aimed solely at increasing taxes through increased regulation and propaganda. Greenwashed products are the epitome of that.
