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

===== Recalculations =====
Since the activity data and emission factors remain unrevised, no recalculations have been carried out compared to last year's submission.
For pollutant-specific information on recalculated emission estimates for the Base Year and 2018, please see the pollutant specific recalculation tables following [[general:recalculations:start|chapter 8.1 - Recalculations]].
===== Planned improvements =====
No category-specific improvements are planned.
