Abstract: The Blacklist is the most strict instrument in the carbon emission trading credit management system. "Provisional Regulations about the Carbon Emissions Trading" stipulates in principle that the State Council's carbon trading authority establishes and exposes "blacklists" of participating institutions and personnel who have seriously violated laws and proved to be untrustworthy, but the application conditions of the "blacklist" system and procedures have not been stipulated, and the relationship between the blacklist system and other credit management systems-specifically expressed in the relationship between Article 39 and Article 44 has not yet been clarified. And a huge difference about the blacklist in many local regulations have been found, which seriously affects the application of the blacklist. This article attempts to clarify the concept of the administrative blacklist system in carbon trading, clarify the applicable conditions and legal procedures of the blacklist system.
