Methodology
Organic chemicals: activity data and emission factors
The annual production volumes for all large volume organic chemicals are extracted from national production statistics 1)) by the Federal Statistical Office.
Organic chemicals comprise:
- Acrylonitrile
- Ethylene
- Ethylbenzene
- Ethylene Dichloride
- Ethylene Oxide
- Formaldehyde (Methanal)
- Methanol
- Phthalic Anhydride
- Propene
- Styrene
- Vinyl Chloride
- Polyethylene (LD/HD)
- Polypropylene
- Polystyrene
- Polyvinyl Chloride
- Styrene Copolymeres
The emission factors for the production of organic chemicals as shown in table 2 and 3 are derived from best reference documents polymers and LVOC mostly for the early years. For later years, plant-specific data on an aggregated level were used.

Carbon Black
The figures for carbon black production in the new German Länder in 1990 were taken from the Statistical Yearbook (Statistisches Jahrbuch) for the Federal Republic of Germany 2); the figures for 1991 and 1992 were estimated, due to confidentiality requirements. The other data for carbon-black production as of 1990 were obtained from national production statistics 3)).
From 2005 onwards, Germany uses activity data calculated from the CO2 emissions of the Emission Trading System (ETS), delivered from the German emission trading authority (DEHSt), and the default CO2 emission factor from the IPCC Guidelines 2006 for carbon black production. A comparison of the statistical data and the emission trading data leads to the result, that the statistical data is most probably overestimated.

Sulphuric acid
The activity data for sulphuric acid production are from the statistical office of Germany.

Chlor-alkali industry
For the mercury losses from the Chlor-alkali industry Germany uses the yearly published data from OSPAR on the plant specific production capacity for the AD and the plant specific emissions from the chlor-alkali industry. Because of the BAT conclusion for the Chlor-alkali industry the production has stopped in 2017. But the emissions of Hg are still continuing, because two plants are producing alcoholates and dithionite and are not regulated by the BAT conclusions for Chlor-alkali production.
