The company also evaluates the carbon emissions from travel and leased vehicles. Extrapolations of the available data show a footprint of 11,000 tons of CO2 for the leased fleet and 4,000 tons of CO2 for business travel for the entire Group in 2020 (previous year: 16,000 and 15,000 tons respectively). Both figures are derived from samples, equivalent to approximately 72% of total energy consumption for the leased fleet and approximately 48% of total contracts for business travel, in each case extrapolated to 100%. The company uses conversion factors published by the International Energy Agency (IEA).

In absolute terms, the total CO2 emissions (scope 1,2 and partially 3) in 2020 summed up to 239,228 tons (previous year: 243,000 tons).
