Explanation of Key Trends - Ammonia

The latest UN ECE protocol aims to minimise the damage caused by acidification, eutrophication, and ground level ozone (known as “Göteborg multi-component protocol”, s. NEC Directive of the EC, adopted in German law through the 33rd Ordinance – 33. BImschV) and obliges the Federal Republic of Germany to reduce NH3 emissions to 550kt by 2010.

Main drivers

The Main Drivers for NH3 emissions are agricultural emissions from Manure Management (NFR 4.B) with 85% of total 1990 emissions and a 26% reduction between 1990-2012 and Agricultural Soils (NFR 4.D) with about 10.7% of total 1990 emissions and stagnating emissions between 1990-2012. Therefore the overall emission trend follows the agricultural emissions with a reduction of 23% between 1990 and 2012. The decrease of NH3 emission in the year 1991 is due to a reduced livestock population that followed after the German reunification, while no explicit trend is discernible for the years since then.
