In Germany about 50% of the organic waste is treated in composting plants and ammonia (NH<sub>3</sub>) is an important emission to air.

-Official statistical data (Statistisches Bundesamt, Fachserie 19, Reihe 1: Abfallentsorgung (Waste management), Table 2.1; [(Statistisches Bundesamt, Fachserie 19, Reihe 1: Abfallentsorgung; Wiesbaden; URL: https://www.destatis.de/DE/Publikationen/Thematisch/UmweltstatistischeErhebungen/Abfallwirtschaft/Abfallentsorgung.html)]) are used for the estimation. The data are published on a yearly basis with an exception for the actual year of reporting. The activity data for the actual year of reporting are obtained, initially, by carrying the relevant data from the previous year forward, in unchanged form. In the following year, when the actual activity data for the given year becomes available, they replace the data that were carried forward. This procedure has only a very small impact on the total emissions in the relevant current report year.+

 +The data are published annualy with an exception for the current year of reporting. Therefore, activity data for the current year of reporting are obtained, initially, by extrapolating the trend of the last 3 years. In the following year, when the actual activity data for the given year becomes available, they replace the extrapolated data. This procedure has only a very small impact on the total emissions in the relevant current report 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. 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.
