-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 CO<sub>2</sub> emission factor from the IPCC Guidelines 2006 for carbon black production.

-For the SO<sub>x</sub> EF from sulphuric acid production there was made a survey 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 or respectively are limit values 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. The reason for this is due to significant process optimizations and technology improvements since 1990.+For the SO<sub>x</sub> EF for sulphuric acid production a survey was made in the year 2019.

-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. At both places also Chlor-alkali was 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 to report the Hg-emissions from dithionite- and alcoholate-production, so CEFIC does not anymore report these emissions to OSPAR.  +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. 
-Germany plans to get a treaty with the two plants to get the Hg-emissions in future directly from these plants. And Germany plans to report these emissions in a new subcategory.+
