Method

Activity data

The yearly production figures were taken from the annual statistical report of the German association for non-ferrous metals [Lit. 1] until 2020. Since 2021 the production figures for primary copper have been directly taken from the producer whereas for secondary copper no updating was possible. In 2022 the primary and secondary copper production amounted to 594.63 kt.

Emission factors

The emission factors are either default values according to the EMEP/EEA air pollutant emission inventory guidebook 2023 [Lit. 2] or determined in research projects [Lit. 3] or from companies environmental reports [Lit. 4]. Nickel emissions in secondary copper production are not reported.

Uncertainties

The uncertainties for the production amounts are 7% and for the emission factors not more than 50% for primary and 200% for secondary copper production.

Recalculations

With activity data and emission factors remaining unrevised, no recalculations were carried out compared to the prvious submission.

Planned improvements

No category specific improvements are planned.
