The department for "Environment and Climate Change" of the Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ) identified the potential of the resource efficiency (RE) approach for the domain "resource efficiency and urban-industrial environmental protection". On behalf of the GTZ, the Wuppertal Institute is providing input for a brochure on resource efficiency and practical experiences. The aim of the brochure is to communicate the RE approach in a scientifically grounded and understandable manner. Furthermore the environmental, resource and climate conservation potential of the RE approach for economic and urban development shall be illustrated. The eight examples taken from real life experiences will be a core element of the brochure. They shall be supported by figures and facts in order to demonstrate the linkages between resource efficiency and environmental, resource and climate conservation.
