Method
Activity data
The yearly production figures were taken from the annual statistical report of the German association for non-ferrous metals [Lit. 1].
Emission factors
The emission factors are either default values according to the 2019 EMEP/EEA air pollutant emission inventory guidebook [Lit. 2] or determined in several research projects. The EF for the heavy metals (HM) are taken from a research project [Lit. 3].

Recalculations
With activity data and emission factors remaining unrevised, no recalculations have been carried out compared to last year's submission.
For more information on recalculated emission estimates for Base Year and 2019, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations.
Planned improvements
No category specific improvements are planned.
