This means that the Clipper Group's hotels in Hamburg, Berlin and Weimar now carry the GreenSign label. Sustainability is very important to us in order to protect the environment and conserve resources. In this way, we ensure a future worth living for generations to come and offer our guests a responsible travel experience. For this reason, we have decided to partner with the GreenSign Institute. The GreenSign sustainability certification, awarded by the GreenSign Institut GmbH from Berlin, is recognised by the Global Sustainable Tourism Council. It consists of five levels that indicate the level of sustainability of a hotel. In order to be certified, a hotel must fulfil a comprehensive catalogue of requirements comprising over 100 criteria in eight core areas. In addition to environmental sustainability, social, cultural and economic aspects are also taken into account. An environmental programme with specific development goals for the future is also required. Following an audit by GreenSign experts, we achieved the second-highest level.
