 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; the production 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. \\ \\ 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; the production for 1991 and 1992 were estimated, due to confidentiality requirements.

-From 2005 onwards, Germany uses activity data, which is calculated from the CO<sub>2</sub> emissions of the Emission Trading System (ETS), delivered by the German emission trading authority (DEHSt), and the default CO<sub>2</sub> 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 conclusion that the statistical data is most probably overestimated.+From 2005 onwards, Germany uses activity data, which is calculated from the CO<sub>2</sub> emissions of the Emission Trading System (ETS), delivered by the German emission trading authority (DEHSt), and the default CO<sub>2</sub> emission factor from the IPCC Guidelines 2006 for carbon black production.

 For the mercury (Hg) losses from the Chlor-alkali industry, Germany used to apply the data annualy published by OSPAR [(ODIMS (OSPAR Data & Information Management System); https://odims.ospar.org/en/search/?dataset=chlor_alkali_data)] on plant specific production capacity for the AD and plant specific emissions from the chlor-alkali industry.  For the mercury (Hg) losses from the Chlor-alkali industry, Germany used to apply the data annualy published by OSPAR [(ODIMS (OSPAR Data & Information Management System); https://odims.ospar.org/en/search/?dataset=chlor_alkali_data)] on plant specific production capacity for the AD and plant specific emissions from the chlor-alkali industry.

Most production sites have switched to membrane technology.
  
-However, Hg emissions are still ocurring because two production sites still continue to use the amalgam process for the production of certain alcoholates not regulated by the BAT conclusions for Chlor-alkali production. Before 2018, these Hg-emissions were reported together with the Hg from Chlor-alkali production. But the OSPAR convention does not request the Hg emissions from alcoholate production to be reported, so CEFIC does no longer report these emissions to OSPAR. +However, Hg emissions are still ocurring because two production sites still continue to use the amalgam process for the production of certain alcoholates, which is not regulated by the BAT conclusions for Chlor-alkali production.
