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 were carried out compared to Submission 2022.
Planned improvements
No category specific improvements are planned.
