The environmental management system of GLS helps implement the measures drawn up as part of the ThinkGreen initiative and achieve the set goals. In 2011, the environmental management system has been certified to the ISO 14001 standard for the first time – in Austria, Belgium, Germany and the Netherlands. Meanwhile all GLS companies have achieved certification
GLS records and monitors its progress in environmental protection on a regular basis. Since 2008/2009, it carries out a group-wide eeco 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.
The GLS quality and environmental management is certified and meets internationally recognised standards. In many subsidiaries, the transport of medicinal products has also already been certified by DQS.
