-The emission factors used for calculating NH3 emissions are based on emission data from a research project ((Carsten Cuhls, Birte Mähl, Joachim Clemens; gewitra Ingenieurgesellschaft für Wissenstransfer mbH: Ermittlung der Emissionssituation bei der Verwertung von Bioabfällen; https://www.umweltbundesamt.de/publikationen/ermittlung-der-emissionssituation-bei-der; im Auftrag des Umweltbundesamtes, April 2015)).+The emission factors used for calculating NH<sub>3</sub> emissions are based on emission data from a research project ((Carsten Cuhls, Birte Mähl, Joachim Clemens; gewitra Ingenieurgesellschaft für Wissenstransfer mbH: Ermittlung der Emissionssituation bei der Verwertung von Bioabfällen; https://www.umweltbundesamt.de/publikationen/ermittlung-der-emissionssituation-bei-der; im Auftrag des Umweltbundesamtes, April 2015)).

-When preparing the current inventory data, statistical data are only available for the previous reporting year, as the Federal Statistical Office's waste statistics are one year behind schedule. The current reporting year must therefore be extrapolated on the basis of the previous year. The result of this approach is revised by the correct data in the following year. For this reason, annual recalculations are required for the previous year. +When preparing the current inventory data, statistical data are only available for the previous reporting year, as the Federal Statistical Office's waste statistics are one year behind schedule.

 +However, for the year 2010, an error has been noticed in the reported waste volume. This error is corrected in the current reporting. Instead of 3.416,300 kt of biowaste as reported in 2020, 3.416,944 kt were used in the anaerobic digestion plants. NH<sub>3</sub> emissions are thus corrected from 936,07 t to 936,24 t for 2010
