-[Da geht noch was]+For the SO<sub>x</sub> EF for sulphuric acid production a survey was made in the year 2019. The producers were directly asked by the association. Based on the data from the producers, new EFs for the years 2017 and 2018 were developed. All emissions were measured by the producers respectively or limit values are specified in the permit decision for the installation. The EF is weighted by the amount of H<sub>2</sub>SO<sub>4</sub> produced. Big producers have more influence on the EF than small producers. The EF is smaller than the Default-EF. This is due to significant process optimizations and technology improvements since 1990.

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 SO<sub>2</sub> emissions from titanium dioxide production and sulphuric acid production, and for Hg emissions from chlor-alkali industry, the emissions of the two last years are always actualized. This is because the emissions of the last year are always a prediction, as the final emissions are still not published by the time of reporting.

 +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. 
 +Germany is trying to ensure reporting of Hg emissions for that sources.
