- | 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. | + | __Table 3: Revised NMVOC emissions, in [kt]__ |
