Urban land-use planning is an important step in the development of construction projects and the design of the city. Urban land-use plans concretize issues of spatial and regional planning and adapt them to local needs. Landscape plans are drawn up for the entire municipal area and form the ecological basis for urban land-use planning, especially land-use planning.

The city of Aachen is pursuing an active climate protection strategy. Together with politicians, it has launched an ambitious 123 million euro program for climate protection. The goal of becoming climate-neutral by 2030 is firmly anchored in the city's society. Business, universities and the city administration are working together to answer the question: Where and how can we reduce CO2 emissions within our own means?
