Method
Activity data
The yearly production figures were taken from the annual statistical report of the German association for non-ferrous metals [Lit. 1]. For 2021 the production figure for primary copper was directly taken from the producer whereas for secondary copper no updating was possible.
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 or from companies environmental reports [Lit. 3].
