Sustainability

More Than Just a Promise

We understand sustainability as a holistic commitment – to nature, to the regions we operate in, and to the people who work and stay with us. As one of Switzerland's leading hotel groups, it is part of our entrepreneurial thinking to actively contribute to environmental protection and a healthy social environment. Because only together can we shape a future worth living in.

As part of the «Cause We Care» initiative and «Swisstainable», we pursue a responsible approach to tourism. We combine climate protection, conscious use of resources and targeted projects to promote biodiversity and regional development. With each passing year, we drive new projects forward that serve nature and our shared future – because sustainability is not a destination you reach once, but a path you walk consistently.

Our commitment is structured around three pillars: ecological responsibility, social engagement and economic stability. They form the foundation of our strategy – for people, nature and region.

Our Partnerships

Sustainability is not a trend for us, but part of our daily commitment. We demonstrate this through targeted, long-standing partnerships and programmes:

                  

           

«Cause we Care»

Together for Climate Protection and Sustainability

Together with our guests, we are committed to effective climate protection. For every person per night, a climate contribution of CHF 1 is automatically included. Sunstar doubles this contribution. Together, we support selected Swiss climate protection projects and additionally invest in our own sustainable initiatives.

Supporting
Climate Protection Projects

The Sunstar Climate Franc is invested in Swiss climate protection projects run by the «myclimate» foundation, as well as in local projects at the individual Sunstar Hotels in support of sustainability.

Energy & Resources

Through the use of modern technologies, we continuously reduce our energy consumption – with energy-efficient lighting, photovoltaic systems and ongoing CO₂ monitoring. Electric buses, EV charging stations and renewable energies complement our measures to reduce energy consumption.

Valuing Food

We actively combat food waste. As a member of «United Against Waste» and a partner of «Too Good To Go», we reduce food waste along the entire value chain.

Sustainable Dining

We prioritise regional, seasonal and responsibly produced ingredients. Meat is sourced predominantly from Switzerland as well as from certified farms abroad. Fish and seafood are sourced exclusively from sustainable stocks. Vegetarian and vegan options are a permanent part of our menu.

In Everyday Hotel Operations

In our day-to-day operations, we pay close attention to the conscious use of resources – through water-saving systems, reduced cleaning cycles and the elimination of single-use products. With reusable solutions such as RePan, we consistently reduce packaging waste. Smart heating thermostats in Arosa and photovoltaic systems in Brissago and Pontresina demonstrate how we put sustainability into practice in everyday hotel life.
