-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 (best available technique) conclusion for the Chlor-alkali industry, the production has stopped in 2017. However, emissions of Hg are still ocurring, because two plants still produce alcoholates and dithionite and are not regulated by the BAT conclusions for Chlor-alkali production. In both plants Chlor-alkali was also produced. The Hg-emissions from the production of dithionite and alcoholates  were so far reported together with the Hg-emissions from Chlor-alkali production. The OSPAR convention does not request the Hg-emissions from dithionite and alcoholate production to be reported, so CEFIC does no longer report these emissions to OSPAR. +For the mercury (Hg) losses from the Chlor-alkali industry, Germany used the yearly published data from OSPAR [(ODIMS (OSPAR Data & Information Management System); https://odims.ospar.org/en/search/?dataset=chlor_alkali_data)] on the plant specific production capacity for the AD and the plant specific emissions from the chlor-alkali industry. Because of the BAT (best available technique) conclusion for the Chlor-alkali industry, the production based upon the amalgam process has stopped in 2017. Most production sites switched to membrane technology. 
 +However, emissions of Hg are still ocurring, because two production sites still continue to uses 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-emissions 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. 
 +As from 2018 PRTR data is used to determine mercury emissions belonging to the alcoholate production. Due to a delay of the 2019 PRTR data the 2018 emission value is used also in 2019 and 2020.

-For the mercury losses from the Chlor-alkali industry, because of the BAT conclusion for the Chlor-alkali industry the production has stopped in 2017. However, emissions of Hg are still ocurring, because two plants are still producing alcoholates and dithionite and were so far reported by CEFIC to OSPAR based on BAT regulation for Chlor-alkali production. Since the OSPAR convention does not request to report the Hg-emissions from dithionite and alcoholate production, CEFIC no longer reports these emissions to OSPAR.  +There are no planned improvements.
-Germany is trying to ensure reporting of Hg emissions for that sources. +
