We use DHL's globally unique GOGREEN service, making an active contribution to environmental protection. The low-emission or emission-neutral GOGREEN shipments are the first of their kind worldwide. They are shipped using alternative vehicles and fuels or by offsetting the CO² emissions caused by transport. The calculation of the CO² emissions caused by transport is carried out by the independent certification company Société Générale de Surveillance according to a verified procedure (ISO 14064) based on the Kyoto Protocol. Furthermore a fixed sum flows into climate protection projects.
