- | In 2019 a total of 27.7 million tonnes of raw steel were produced in six integrated steelworks. Electrical steel production amounted to another 11.9 million tonnes.\\ | + | 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.\\ |
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. The last Thomas steelworks (Maxhütte Sulzbach-Rosenberg) discontinued its production in 2002. Due to their minor relevance and their phase-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).

+ | 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 implemented with the submission 2022 the recommendation to only report total-PAHs for the whole time series. Therefore a national total-PAH emission factor for pig iron production needed to be deduced. | ||
