 The structural elements of this category are the production of pig iron (blast furnaces), sponge iron (direct reduction), sinter, rolled steel, iron and steel casting, Siemens-Martin steel (in the new German Länder only until shortly after 1990), electric steel and the power stations and boilers of the entire steel production. The structural elements of this category are the production of pig iron (blast furnaces), sponge iron (direct reduction), sinter, rolled steel, iron and steel casting, Siemens-Martin steel (in the new German Länder only until shortly after 1990), electric steel and the power stations and boilers of the entire steel production.

 ===== Recalculations ===== ===== Recalculations =====
  
-Recalculations were necessary for the latest reference year due to the availability of the National Energy Balance. Germany's federal structure causes a time lag for the National Energy Balance. Therefore recalculations are always necessary. +Recalculations were necessary for 2022 due to the implementation of the now finalised National Energy Balance.
