Explanation of Key Trends - Ammonia

Last updated on 09 Oct 2018 06:49 (cf. Authors)

Obligations

Germany has made a commitment under the Gothenburg Protocol to reduce ammonia emissions. Since 2010, it is no longer permissible to exceed a National Emission Ceiling of 550kt NH3 for Germany as whole. The revised Gothenburg Protocol and the revised NEC Directive both define emission reduction targets relative to a 2005 base year, mandating 5% (2020) and 29% (2030) reductions respectively.

Further details can be found in Chapter 9 - Projections and Chapter 11 - Adjustments and Emission Ceiling Exceedance.

Main drivers

The Main Drivers for NH3 emissions are agricultural emissions from Manure Management (NFR 4.B) with 43% of total 1990 emissions and a 18% reduction between 1990-2016 and Agricultural Soils (NFR 4.D) with even 53% of total 1990 emissions and just a 7,5% decrease between 1990-2016. The overall emission trend mainly follows the agricultural emissions as a whole (-12% between 1990 and 2016) with a total reduction of 10.8% between 1990 and 2016. 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.
