The 4-star superior hotel Valsana in Arosa consistently implements sustainability. It has been Green Globe certified in 2020, making it one of the most sustainable hotels in Switzerland. Green Globe certification is a globally recognized, structured assessment of the sustainability performance of travel and tourism companies and their supply chain partners.

As part of the certification process, all areas of the hotel's operations were evaluated and reviewed for the sustainability thinking behind them. This includes, among other things, employee training in the area of sustainability, integration into the local community, but also a purchasing policy that primarily takes local and regional producers into account. Valsana achieved 93 percent of the possible points in the certification process. In addition to the ice storage, the hotel's own beehive, the green roof and the majority of eco-certified and fair-trade products were particularly highlighted.
