The company also evaluates the carbon emissions from travel and leased vehicles.
Extrapolations of available data show a footprint of 20,000 tons of CO² for the leasing fleet and 14,000 tons of CO² for business travel for the entire Group in 2018 (previous year: 22,000 and 16,000 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.
