-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.

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. +
