IGES Kyoto Units Transfer Database


The IGES Kyoto Units Transfer Database (CP1 & CP2) aims to provide compiled information on issuance, international transfer, retirement, and cancellation of Kyoto units from each Annex I country or among different Annex I countries for the first and second commitment periods of the Kyoto Protocol (CP1 and CP2). The information is extracted from publicly available sources on national registries from the UNFCCC website and the data includes the latest information available at the time of its update.
