A “Serialized CoU” (Certificate of Use) in carbon credit terminology refers to a carbon credit that has been issued with a unique serial number. This serialization process is crucial for tracking and verifying the authenticity of carbon credits to prevent double counting and ensure transparency in the carbon market. When a carbon credit is serialized, it means that each credit is tagged with a specific identifier, which allows it to be tracked from creation through various transactions until it is retired. This process enhances the integrity of carbon credits and provides confidence to buyers that the credits they purchase are legitimate and correspond to real reductions in greenhouse gas emissions. For more detailed information, you can refer to resources such as the Mintz glossary on carbon market terms or Carbon Brief’s guide to carbon offsets.
