Urban planning takes physical, social, and environmental factors into account and determines the allocation, development, and use of buildings, infrastructure, and parks. It has a major impact on how people and goods move through a city and can strongly influence whether materials, products, and resources can be reused and kept in use. It can also lead to long-term housing patterns, mobility patterns, and behavioral lock-ins. Therefore, incorporating the principles of the circular economy into urban planning decision-making is invaluable.
