 The Main Drivers for NH<sub>3</sub> emissions are agricultural emissions from **Manure Management (NFR 4.B)** with 43% of total 1990 emissions and a 30% reduction between 1990-2021 and **Agricultural Soils (NFR 4.D)** with even 53% of total 1990 emissions and a 31% decrease.  The Main Drivers for NH<sub>3</sub> emissions are agricultural emissions from **Manure Management (NFR 4.B)** with 43% of total 1990 emissions and a 30% reduction between 1990-2021 and **Agricultural Soils (NFR 4.D)** with even 53% of total 1990 emissions and a 31% decrease.

 The decrease of NH<sub>3</sub> 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 up to 2016. Between 2016 and 2021 the emissions are dropping every year adding up to a 15% drop. Here, emissions dropped by 9.7% between 2019 and 2020, an decrease only topped by the reduction between 1990 and 1991 (minus 11%). The decrease of NH<sub>3</sub> 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 up to 2016.
