SKKG is dedicated to preserving and promoting cultural heritage and enabling participation in it. This also includes properties and land managed by Terrestra Immobilien- und Verwaltungs AG, which belongs to the foundation. To fulfil this mission in a world of climatic and social change, the foundation commissioned intep to develop a sustainability strategy. To do so, a shared understanding was first established, the foundation’s needs and requirements were explored in a potential analysis, and fields of action were identified. Building on this, a target vision was developed from which concrete goals and measures could be derived.
