Green Key – the international eco-label for tourism
Sergenten has been Green Key certified since autumn 2025 – something we are proud of.
Green Key is an international sustainability certification for tourism businesses. It sets requirements for areas such as environmental practices, resource use and responsible procurement. Certification requires thorough documentation, regular monitoring and continuous efforts to meet Green Key’s criteria.
At Sergenten, sustainability is part of our everyday operations. We have an environmental action plan and a responsible procurement policy, and 90% of the cleaning products used for our daily cleaning are eco-labelled. We sort our waste and monitor our energy and resource consumption to help reduce our environmental impact.
Sergenten name
For decades, Denmark’s sergeants were trained at the now closed Sønderborg Barracks. Sergenten is located in the barracks’ old workshop building, which has been completely renovated and modernised.
In the same way that people flocked to Sønderborg for years to train as sergeants, our event venue will attract people to Sønderborg, where experiences, knowledge, networks and growth await.
That is why the place was named Sergenten.
