Sustainability strategy

Climate Protect

GLS Slovenia strategy is based on the reduction, avoidance and compensation of emissions. Our priority is to reduce and avoid emissions.This includes emissions that come from our physical operation and those that come from indirect sources, such as purchasing electricity or heat for our buildings. Reducing and avoiding emissions is crucial to our long-term ambition of reaching zero emissions in 2045. To offset our emissions, GLS Slovenia has teamed up with ClimatePartner to support projects that prevent CO2 from being emitted. ClimatePartner protects existing forests and invests in the expansion of renewable energies around the globe for climate protection.
