On October 2, 2024 three U.S. agencies moved against one carbon-credit developer, charging its founder over allegedly false cookstove data, in the voluntary market's first fraud action. The episode sorts carbon-market wrongdoing into criminal, civil, legal-but-wrong over-crediting, and unadjudicated allegation. The frauds that reached court concerned money or measurement, while the market's largest losses came from things that broke no law.

Still debated
