The Tschuggen Collection has set a target for all properties to work towards the eventual elimination of all fossil fuels by 2025. A new heating and cooling system utilizing water from the lake and groundwater at the Hotel Eden Roc is expected to decrease fossil fuel usage by a further 20%. This will be followed by a new energy concept, the installation of a photovoltaic façade for the Tschuggen Grand Hotel. From there, new developments will take place toward the achievement of 100% renewable energy.
