The Voluntary Carbon Market currently lacks regulation by any governmental entities. The rules are established by non-profit organizations such as the International Carbon Reduction Offset Alliance (ICROA) and the International Emission Trading Agency (IETA).
Additionally, some Net Zero protocols, such as the Science-Based Targets Initiative (SBTi) and Carbon Trust, establish their own regulations on the acceptance of carbon credits. These criteria largely align with the guidelines outlined by the ICVCM.
Finally, some countries are beginning to define laws concerning the quality and usage of carbon credits. Notably, in France, the "Code de l'Environnement" and the "Decret de loi sur la compensation carbone et les allégations de loi sur la neutralité carbone" establish certain criteria.
