Continuously tracking our environmental
performance
Further remarks:
All figures are rounded.
Absolute values may vary on a year-on-year comparison due to different
production levels and are therefore not a direct reflection of environmental
performance.
Reporting boundaries:
Unless otherwise stated, the data relates to fully consolidated group companies of
the actual fiscal years. Since these figures are calculated only at the end of the
year they include the group of companies consolidated as it stands at year-end.
The figures include the 50 percent share in Hüttenwerke Krupp Mannesmann
GmbH in accordance with IFRS rules.
Methodology for CO2:
CO2 emissions are calculated using the GHG Protocol methodology. The
emissions are calculated on the basis of energy consumption and process
emissions applying generally accepted Scope 1 and 2 emission factors from
IPCC, IEA and certified own measurements. For Scope 2 emissions the location-
based approach has been applied using emission grid factors.
1 Portfolio-adjusted according to the financial control approach of the GHG
Protocol.
