-Activity data are determined via summation of figures for individual plants (until 1994, activity data were determined on the basis of data of the official member association BDZ). As of 1995, following optimisation of data collection within the association, activity data were compiled by the   [[https://www.vdz-online.de/home1.html?&L=1|German Cement Works Association]] (VDZ), and by its [[https://www.vdz-online.de/en/vdz/research-institute/|VDZ research institute]] (located in Düsseldorf), via surveys of German cement plants. The data are supplemented with data for plants that are not BDZ members (in part, also VDZ estimates). +//cement clinker//

 For internal reasons within the association, the data for the years from 2015 onwards is not available from the VDZ. Instead, the cement clinker specification is based on aggregated plant specific ETS-data of DEHSt. A comparison for the years 2005-2014 showed a good correlation between information of the European Emissions Trading (ETS) and the cement clinker production data of the VDZ. So, the cement clinker information from 2015 onwards is based on aggregated data of ETS. All companies are required to report production data within the framework of CO₂-ETS. The EU monitoring guidelines for emissions trading specify a maximum accuracy of 2.5%. For internal reasons within the association, the data for the years from 2015 onwards is not available from the VDZ.

 Furthermore CKD was taken into account.  According to the VDZ, the share of bypass dust in clinker production was between 1% and 2% between 2009 and 2016. For the inclusion as an activity rate, it can be assumed that the share was 2 % from 2009 onwards, for time before only 1%. Furthermore CKD was taken into account.  According to the VDZ, the share of bypass dust in clinker production was between 1% and 2% between 2009 and 2016.

 Emissions of HCB are not applicable according to a research result. The table of EF is related to two different AD sets. For purposes of the most pollutants the AD is burnt clinker. For purposes of emission estimation of PM the AD is grinded clinker (included further materials as domestic burnt clinker). NFR tables could provide only one AD (burnt clinker). Emissions of HCB are not applicable according to a research result. The table of EF is related to two different AD sets.
