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].

Table 1: Tier1 emission factors applied for entire time series

Pollutant EF Unit
SO2 1.35 kg/t
PM2.5 0.0385 kg/t
PM10 0.0613 kg/t
TSP 0.100 kg/t
As 123.882 mg/t
Cd 1,085.046 mg/t
Hg 0.5 g/t
Pb 19,604.578 mg/t
Zn 51.968 mg/t
PCDD/F 0.15 µg/t

Uncertainties

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 2018, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations.

Planned improvements

No category specific improvements are planned.
