-The Main Drivers for NH₃ emissions are agricultural emissions from **Manure Management (NFR 4.B)** with 43% of total 1990 emissions and a 26% reduction between 1990-2020 and **Agricultural Soils (NFR 4.D)** with even 53% of total 1990 emissions and a 32% decrease between 1990-2020. The overall emission trend mainly follows the agricultural emissions closely with a total reduction of 25% between 1990 and 2020. 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 up to 2016. Between 2016 and 2020 the emissions are dropping every year adding up to a 15% drop. Between 2019 and 2020, emissions dropped by 6.6%, only topped by the reduction between 1990 and 1991.
