-For the estimation of NMVOC, Germany decided against the proposed EF of the EMEP/EEA Guidebook 2019, but instead for the Tier 1 approach of the US-EPA which is also reproduced there (Part B, 5.A, chap. 3.2.2, p. 5; ((EMEP/EEA, 2016: EMEP/EEA air pollutant emission inventory guidebook 2019, Copenhagen, 2016))). According to national experts in the field, the approach of the US-EPA is more likely to produce better data, because the ratio between NMVOC (1.3 %) and CH<sub>4</sub> (98.7 %) in VOC from landfill gas is scientifically sound and assumed to be the very same in Germany. Also, already existing and published data for methane emissions from landfills, derived from the IPCC-FOD Waste Model (see NIR of Germany), can be used.+For the estimation of NMVOC, Germany decided against the proposed EF of the EMEP/EEA Guidebook 2019, but instead for the Tier 1 approach of the US-EPA which is also reproduced there (Part B, 5.A, chap. 3.2.2, p. 5; [(EMEPEEA2019>EMEP/EEA, 2019: EMEP/EEA air pollutant emission inventory guidebook 2019, Copenhagen, 2019)]).

 Regular back-calculations are required annually for the previous year, since the waste statistics of the Federal Statistical Office are published with a one-year delay for the data on the quantities and compositions of waste deposited, so that the current reporting year must therefore be estimated. The estimate is replaced in the following year with the then current data.\\ Regular back-calculations are required annually for the previous year, since the waste statistics of the Federal Statistical Office are published with a one-year delay for the data on the quantities and compositions of waste deposited, so that the current reporting year must therefore be estimated.

-In this year's reporting there was a need for correction in addition to the reasons described above. In the past, an incorrect CH4 content (41% instead of 45%) was expected for landfills in the landfill and decommissioning phase in 2016, which also has an impact in 2015 and 2017. In addition, there was a marginal calculation error in the summation of sewage sludge going to landfill. For the reasons given above, a recalculation was necessary (see following table).+However, in this year's reporting the need for correction of PM and TSP is higher than usual and thus a recalculation is reported (see following table).

 +Additionally, in this year’s reporting, the density of methane used for the calculations was consolidated with other inventory categories. The value was adjusted from 0.716 to 0.717 kg/m³. This results in a very small change in reported NMVOC emissions over the entire time series. Due to their insignificance, the changes are not explicitly reported here.
