German Informative Inventory Report 2026

Abstract

The Informative Inventory Report (IIR) is providing complementary information to Germany's air pollution inventories under the Geneva Convention on Long-range Transboundary Air Pollution of the United Nations Economic Commission for Europe (UNECE/CLRTAP) as well as the EU's National Emission Ceiling Directive (NECD). Germany's air pollution inventory includes emission data in consistent time-series ranging from 1990 (1995 for PM10 , PM2.5 and 2000 for Black Carbon) to the latest reported year for all 26 air pollutants or groups of air pollutants (NOx , NMVOC, PCDD/PCDF) considered under UNECE reporting. This report provides a comprehensive analysis of the inventory data, descriptions of the methods applied, data sources, and carried out QA/QC procedures. It follows the outline established by the latest guidelines for estimating and reporting of emission data and all data presented in this report were compiled according to those same guidelines. However, this report does not provide a comprehensive discussion on air pollution or the measures and politics dealing with it. Such information is included in the published national programs for further emission reductions, e.g. under the NEC directive or the trend and projection reports for green-house gases. Instead, it provides a detailed insight on the process of air pollution and emission inventory preparation. The focus lies on the methods and assumptions used for the German emission reporting and to underpin the “technical” review of the emission data as reported under the CLRTAP convention and its protocol.
