Eco footprint
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.


GLS Slovenia supports green activities: ThinkGreen
Dušan Puh Sailing Team
Project Adriatic Europa
In 2008, GLS launched the ThinkGreen environmental initiative to coordinate and actively promote various green activities within the GLS Group. As part of this, due to their focus on the support and promotion of sailing, ecology and natural development potentials of the Adriatic Sea, we decided to advocate and proudly sponsor green activity or in this case, the green sport Adriatic Europa represent so well.
