Germany, as a party to the Framework Convention on Climate Change, has an obligation to prepare emissions inventories and publish them at regular intervals. To meet these reporting requirements, Germany operates the Central System for Emissions (Zentrale System Emissionen – ZSE), a comprehensive database that is used both to calculate and to manage and document relevant emission data. In the light of ongoing advances, the inventory database is constantly updated to take account of the latest research findings and internal and external analyses.
