 +In 2020 a total of 24.1 million tonnes of raw steel were produced in six integrated steelworks. Electrical steel production amounted to another 11.5 million tonnes.\\
  
-The last Siemens-Martin steel works (Stahlwerk Brandenburg) was shut down shortly after 1990; the last Thomas steel works (Maxhütte Sulzbach-Rosenberg) discontinued the production in 2002. Due to their minor relevance and the phasing out, the emissions from Siemens-Martin and Thomas steel production are jointly calculated with the emissions from oxygen steel production.\\ +Other structural elements are sinter production, hot iron production, hot rolling, iron and steel foundries (including malleable casting). The last Siemens-Martin steelworks (Stahlwerk Brandenburg) was shut down shortly after 1990.

-Energy-related emissions from steel production for the years 1990 1994 (for individual pollutants until 1999) are reported under [[:sector:energy:fuel_combustion:industry:iron_and_steel | 1.A.2.a]].+Energy-related emissions from steel production for the years 1990 to 1994 (for individual pollutants until 1999) are reported under 1.A Fuel combustions in the respective subcategory [[:sector:energy:fuel_combustion:industry:iron_and_steel | 1.A.2.a]]. A detailed explanation for the individual pollutants is also found there.
  
-In 2019 a total of 27.7 million t of raw steel was produced in six integrated steelworks. Electrical steel production amounted to another 11.9 million t.

-Activity data are surveyed plant specific and submitted by national statisticsAfter discontinuation of the special statistics for iron and steel production (FS. 4, R. 8.1), the information is collected by the German steel trade association Wirtschaftsvereinigung Stahl (WV Stahl) based on a formal agreement. +Activity data is collected from plant operators by national institutionsSince the discontinuation of the special public statistics for iron and steel production (FS. 4, R. 8.1), the information is collected by the German steel trade association Wirtschaftsvereinigung Stahl (WV Stahl) based on a formal agreement. 
-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. To date, these materials have not yet been included in the national statistics and in the Energy Balance. For this reason, the data used was provided by the steel trade association (Wirtschaftsvereinigung Stahl).+ 
 +As the activity rates for 2017 could not be provided by WV Stahl as a result of compliance issues, aggregated figures from emissions trading were used instead. The consistency of emissions trading data was verified against comparative figures for previous years. The deviations were less than 1%; only in sinter production were they noticeably higher (maximum + 8%).

 === Emission factors === === Emission factors ===
  
-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). \\ +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.+
  
-Please note that the reported emissions now also cover diffuse emissions from sources that were not covered in previous reporting periods, nor in the EMEP/EEA Guidebook. For many pollutants and sources, individual EFs for channelled as well as diffuse emissions have been determinedWhile there is sufficient knowledge and measurement data of channelled emissionsthe 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 plantsThe emission factors given below were calculated as the weighted average of pollution loads reported for individual diffuse sources by the plant operatorsin relation to their corresponding production amounts.+As the EF for the years 1995 to 2001 as well as for 2008 are based on real stack emission dataSince 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 laterall emissions are reported under 2.C.1\\

 +**HCB** 
 + 
 +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. 
 ===== Planned improvements ===== ===== Planned improvements =====
  
-HCB emissions have not been included in iron production till German Informative Inventory Report 2021 due to lack of emission data (notation key NE). And the standard emission factor is not seen as appropriate. In order to overcome this data gap, information search will be done within the scope of a Project for actualizing several emission factors. The project should start in 2021 and is designed to run three years. As long as there is no country specific emission factor for HCB the standard emission factor is used. In implementing the EMEP/EEA Guidebook standard emission factor Germany is following recommendations provided by the Expert Review Team for the NECD-Review in 2020.+no improvements planned.
