For climate-friendly logistics, our quality management has all system partners certified according to DIN EN 16258; each partner is obliged to record the weight, fuel consumption and kilometres driven for each transport and to store this data in the system portal. We have been preparing the CO2 footprint of our transport services in accordance with this standard since June 2014, and thus ensuring transparency. At the same time, all the system partners are working to further reduce CO2 emissions by training driving personnel and optimising capacity utilisation.
