• Cities today seek ways to comply with national climate targets. The urban authorities responsible for city planning are therefore responsible for defining the eco-efficiency of cities for decades to come. They need clear guidelines on how to reduce greenhouse gas emissions from the building stock in a specific area. The use of sustainably sourced wood in construction plays an increasingly vital part in the transition towards eco-cities. Drawing on an exemplary development site in Munich, this paper describes how the sale of building plots can be connected to an agreement to build with wood. Based on an actual research project, site-specific target values regarding greenhouse gas emissions and the amount of renewable material for specific building plots were developed by studying life cycle assessments for different buildings. Wood is introduced as a building material to achieve a minimal environmental footprint. The focus is set on linking the sale of building plots to an agreement to build primarily with wood. Target values for the buildings were developed in close cooperation with the city and were linked to the tendering of the plots. The proceedings and its implementation are shown in this paper.
