 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). 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 PM<sub>10</sub>, PM<sub>2.5</sub> and 2000 for Black Carbon) to the latest reported year for all 26 air pollutants or groups of air pollutants (NMVOC, PCDD/PCDF) considered under UNECE reporting. +Germany's air pollution inventory includes emission data in consistent time-series ranging from 1990 (1995 for PM<sub>10</sub>, PM<sub>2.5</sub> and 2000 for Black Carbon) to the latest reported year for all 26 air pollutants or groups of air pollutants (NO<sub>x</sub>, 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. This report provides a comprehensive analysis of the inventory data, descriptions of the methods applied, data sources, and carried out QA/QC procedures.

 A decrease of emissions is seen for all pollutants, though progress varies: Sulphur dioxide and TSP (total suspended particles), for example, saw a rapid decline in the early 1990s while the decrease of other pollutant's emissions developed more or less linear. Values for particulate matter are measured and calculated since 1995 and reveal a slow though steady improvement. A decrease of emissions is seen for all pollutants, though progress varies: Sulphur dioxide and TSP (total suspended particles), for example, saw a rapid decline in the early 1990s while the decrease of other pollutant's emissions developed more or less linear.

 Nevertheless, the above figure also illustrates that for certain pollutants (namely ammonia, sulphur dioxide, and total suspended particles) only moderate progress can be observed since 2000. This particularly holds true for the development of ammonia, where recent years saw steady or even increasing emissions. Nevertheless, the above figure also illustrates that for certain pollutants (namely ammonia, sulphur dioxide, and total suspended particles) only moderate progress can be observed since 2000.

 For heavy metal and POP (Persistent Organic Pollutants) emissions, the picture is far more heterogeneous: While the release of these substances generally declined, some trends appear to be less favourable. Generally, data completeness and inventory compatibility remains an issue for these pollutants. For the three priority heavy metals cadmium, mercury, and lead, however, very significant reductions have been achieved in the 1990s (see figure below). For heavy metal and POP (Persistent Organic Pollutants) emissions, the picture is far more heterogeneous: While the release of these substances generally declined, some trends appear to be less favourable.
