-Other structural elements are sinter production, hot iron production, hot rolling, iron and steel foundries (including malleable casting). The last Siemens-Martin steel works (Stahlwerk Brandenburg) was shut down shortly after 1990; the last Thomas steel works (Maxhütte Sulzbach-Rosenberg) discontinued its production in 2002.

A detailed explanation for the individual pollutants is also found there.

The consistency of emissions trading data has been verified against comparative figures for previous years.

-In the iron and steel industry, only minor amounts of secondary fuels are used for pig iron production in individual blast furnaces. They are used as substitute reducing agents, instead of coke and coal. To date, these materials have not yet been included in the national statistics and in the Energy Balance. For this reason, the data used is also provided by the steel trade association (WV Stahl).+In the iron and steel industry, only minor amounts of secondary fuels are used for pig iron production in individual blast furnaces.

-The emission factors used for emissions calculation are based on emission data from individual plants, either determined by the Umweltbundesamt (UBA) itself (emission factors for 1995 - 2001) or by a research project (emission factors for 2008 and later). \\+The emission factors used to calculate emissions are based on emission data from individual plants. The emission factors for 1995 to 2001 were determined by the German Environment Agency (UBA for its initials in German) itself and those for 2008 and later through a research project. \\
  
-As the EF for the years 1995 2001 as well as for 2008 are based on real stack emission data, it is not possible to distinguish between combustion and process emissions (they are emitted via the same stacks). Hence whereever plant-based EF were availaible, i.e. for most pollutants for the years 1995 and later, all emissions are reported under 2.C.1.\\+As the EF for the years 1995 to 2001 as well as for 2008 are based on real stack emission data. Since both combustion and process-related emissions are released through the same stacks, emission factors could not be calculated individually for combustion or process-related emissions. Hence, wherever plant-based EF were availaible, as it the case for most pollutants for the years 1995 and later, all emissions are reported under 2.C.1. \\
  
-Please note that the reported emissions also cover diffuse emissions from sources that are not covered in the EMEP/EEA Guidebook. For many pollutants and sources, individual EFs for channelled as well as diffuse emissions have been determined. While there is sufficient knowledge and measurement data of channelled emissions, the emission data concerning diffuse sources is usually based on estimationsusing parameters adapted to the local conditions of the individual emission source. Therefore, emission data for one source of diffuse emissions is hardly significant for the diffuse emissions from other plants. The emission factors given below were calculated as the weighted average of pollution loads reported for individual diffuse sources by the plant operators, in relation to their corresponding production amounts.+Please note that the reported emissions also cover diffuse emissions from sources that are not covered in the EMEP/EEA Guidebook.

 +For **sinter production**, as long as no country specific emission factor for HCB has been derived, the standard emission factor is used. By implementing the EMEP/EEA Guidebook standard emission factor, Germany is following recommendations provided by the Expert Review Team for the NECD-Review in 2020.

 +**PAH**
 +
 +In the 2021 review the application of a consistent methodology in reporting of PAH emissions in 2C1-iron and steel production was claimed. As there is not enough data available to report individual PAHs Germany decided to only report total-PAHs for the whole time. But for pig iron production a national total-PAH emission factor was missing. For that source the national inventory solely included BaP emissions. Due to the limitation of data the total-PAH emission factor for pig iron production was derived from the BaP emission factor on the basis of the following conservative ansatz (not changing the overall PAH emission trend): 
 +Emissions of PAH depend on the coating material used. The emission factor in table 3.8 of the actual emission guidebook 2019 for pig iron production (2500 mg/t) is only valid for tar containing coating material and excluded abatement technics. Both assumptions are not appropriate for Germany. As tar-free materials are used for coating PAH emissions should not play any role. And the blast furnace gas is conducted and used. But as PAH emissions could not be surely ruled out and in order to avoid an underestimation of PAH emissions in pig iron production the emission factor for total-PAH is set to the 10-fold of the BaP emission factor.

-HCB emissions from iron and steel production have not been included so far due to a lack of emission data (notation key NE)In the past, the standard emission factor was not considered as appropriate, because it was unclear from what kind of data the factor was derived from and to which process/activity rate it actually referred to. In order to overcome this data gap, information will be collected within the scope of a reserach project for updating and completing the emission factors for the sector. The project will start in 2021 and is designed to run three years. \\ +no improvements planned.
