Environmental research shows that greenhouse gas emissions caused by humans - and especially those of carbon dioxide (CO2) - account for the majority of global warming. Climate change is one of the biggest challenges of the 21st century. Unfortunately, the implications for people, animals and the environment are becoming ever more dangerous. Hardly a day goes by when we don't hear about weather-related natural disasters, melting glaciers or rising sea levels.
That is why sustainability is becoming more and more important to Sunstar – not only for environmental reasons but for economic and social reasons, too. For Sunstar, sustainability is more than just a buzzword. The Sunstar Hotel Group has been committed for years to going the extra mile with regard to sustainability at all levels. In this way we are helping to safeguard the long-term health of everyone, everywhere, and the wellbeing of our guests and employees in particular. Naturally, nature herself is at the heart of everything we do. The unspoilt scenery and cultural characteristics and values of a tourist destination are its most important capital assets.
As early as November 2019, Sunstar implemented the business model of the Swiss myclimate foundation, enabling the Group to contribute even more to regional climate protection. Since 2023, we have also been part of Swisstainable, the leading sustainability label for the Swiss tourism industry as a whole.
Under the "Cause We Care" initiative, we give our guests the option of actively making a useful contribution to climate protection by giving a voluntary donation. Sunstar Hotels doubles this contribution and uses part of it to support worthwhile climate protection projects. Sunstar invests the remaining amount in local sustainability measures.
With the latest initiatives, our commitment is becoming even more tangible. For example, we are working with "Bienen Schweiz" to boost biodiversity by creating flowered areas that are really important for pollinators. We are also involved in woodland protection projects and, as an "Uszit-Bier" partner, are helping with eco-friendly woodland regeneration.
We want you to enjoy the joy of life and a high quality of life – after all, that's our overall strategy – and have lots of memorable holiday experiences at our Sunstar hotels. Thank you very much for your support. Because, when it comes to sustainability, we all have to do our bit – just as we all benefit from it.
"Swisstainable" is a sustainability programme run by the Swiss Tourist Board that supports environmentally-friendly and sustainable practices in tourism. This programme is crucially important nowadays, because it's all about responsible tourism that protects Switzerland's unspoilt beauty.
By participating in it, we are confirming our ongoing commitment to seven key aspects of sustainable development: mobility, water, nature conservation, air quality, food and recycling.
Overall, "Swisstainable" is a significant initiative to promote sustainable tourism and protect Switzerland's natural resources while at the same time offering visitors to our country a worthwhile and environmentally-friendly experience.

Here at Sunstar, we believe that we can make a tangible difference to the world around us. So we are all the more delighted to introduce to you our latest partnership, with "Bienen Schweiz" and its "flowered areas" project. The aims of the project are to promote biodiversity and environmental sustainability and to create or preserve flowered areas that provide an important habitat for bees and other pollinators. These efforts are vital if we are to protect both natural beauty and environmental balance in our local areas.
"Uszit" is a Swiss company that is working in innovative ways to preserve and regenerate woodland areas. As one of its key partners, Sunstar is playing an important role in various reforestation projects, as well as helping to raise awareness of woodland issues among the general population and get people more involved.
Responsible use of resources to protect the environment is important to us. As part of the myclimate initiative “Cause We Care”, we work together with our guests to make an effective contribution to environmental and climate protection.
The climate contribution is an integral part of every booking, regardless of the booking channel. With CHF 1 per booking, you automatically contribute to local climate protection measures.
Sunstar matches the amount contributed by our guests. Together, we support selected Swiss climate protection projects that avoid or reduce emissions. Part of the total amount is allocated to high-quality climate protection projects run by the myclimate Foundation.
• I care – With every booking, you automatically contribute CHF 1 per booking (mandatory) to climate protection. This contribution supports local climate protection measures as well as selected Swiss climate protection projects.
• We care – Sunstar matches the contribution made by our guests. Together, we support selected Swiss climate protection projects as part of the “Cause We Care” initiative and also invest in our own climate protection measures.
• We share – That fund is used to offset the emissions from your holiday with myclimate projects. Sunstar also invests in internal climate protection measures
By voluntarily avoiding the use of potential timber stocks, forestry management for this forest area in the region of Prättigau and Davos is optimised in terms of climate, and CO₂ is thus permanently removed from the atmosphere.

Family business Grob Gemüse uses heat from two boreholes to warm its greenhouses. The replacement of natural gas heating with geothermal energy helps significantly reduce CO₂ emissions generated by energy-intensive vegetable production.
