The company also evaluates the carbon emissions from travel and leased vehicles. Extrapolations of available data show a footprint of 22,000 tons of CO2 for the leasing fleet and 16,000 tons of CO2 for business travel for the entire Group in 2017 (previous year: 20,000 and 13,800 tons respectively). Both figures are derived from samples of approximately 72% of total leasing car energy consumption and approximately 48% of total travel contracts both extrapolated to 100% of the fleet and travel, respectively.

The company uses conversion factors as published by the IEA, International Energy Agency.
