      Key figures on environmental protection

      In the production units, we are working on making processes more efficient and more sustainable. New targets were defined in 2019 for operational environmental protection. In addition to reducing CO2 emissions at our locations and increasing the waste recycling rate, these include reducing energy use and increasing energy efficiency, as well as reducing water consumption and waste generation.

      2 Includes the relevant production and research and development locations. 
      3 CO2 emissions from fleet consumption are only partially and not systematically included. 
      4 Scope 2 calculated using the market-based calculation method of the GHG Protocol. Where contract-specific emission factors were not available, the standard emission factors from Defra (November 2019) were used.
