INFRASTRUKTUR & UMWELT supports regions, cities and municipalities in climate protection and a sustainable transformation of the energy industry: With integrated climate protection concepts, strategies and plans for increasing energy efficiency and for the energetic redevelopment of urban quarters. In doing so, we combine urban planning and urban development approaches with energy- and climate-oriented objectives. Parallel fields of action and the need for action are dealt with in an integrated manner. This strengthens the municipality’s ability to act: urban planning aspects, the challenges of climate protection and adaptation to climate change, but also the goals of a sound budgetary policy are taken into account in sustainable and implementation-oriented concepts and recommendations for action.

We all know how pressing the challenges of climate protection are. And we have opportunities to do something at various levels, for example through greater energy efficiency and the intelligent use of renewable energy sources, or through sustainable integrated urban development. It’s good if we can learn from our European neighbors – and they from us.
