 In category **5.D.1**, __NMVOC emissions__ from domestic and commercial wastewater handling are reported. The domestic section is covered by wastewaters of municipal origin (large centralised plants; ranging from 1,000 up to >100,000 resident values). The commercial section is covered by industrial and commercial wastewaters, co-treated in municipal wwt-plants. In category **5.D.1**, __NMVOC emissions__ from domestic and commercial wastewater handling are reported.

-Recalculations were not necessary. +Recalculations had to be executed for the years 2020 – 2023 because of new statistical data for 2022. Therefore, it was necessary to replace data that had formerly been extrapolated. Data for 2020 and 2021 are now interpolated and data for 2023 and 2024 are extrapolated. The amount of total wastewater reported for 2022 is smaller than the formerly extrapolated value. Therefore, the amount of the reported emissions for the years 2020-2023 are slightly decreasing.
