EcoVadis is an international sustainability ratings provider for more than 90,000 companies offering the leading solution for monitoring and optimising sustainability in global supply chains. EcoVadis holds companies to the highest possible standard, which means that GLS’ placement in the 93rd percentile makes it one of the most sustainable parcel carriers in Europe.

GLS records and monitors its progress in environmental protection on a regular basis. Since 2008/2009, it carries out a group-wide eco footprint assessment in which data on emissions, resource consumption and waste disposal is gathered. In its current sustainability report GLS publishes emission development data. The method used for calculating emissions corresponds to ISO 14064-1 standard and the Greenhouse Gas Protocol. GLS calculates carbon dioxide emissions per parcel based on its eco footprint.
