Cities are responsible for about 75% of the global greenhouse gas emissions. Various materials and energy sources, which are mostly produced by the rural areas rather than the cities, are consumed by the cities, and their waste is released back into the rural areas, thereby causing evident environmental damages. The Rural–Urban Metabolism approach can offer a comprehensive tool to understand the flux of resources that cross the urban environments and plan for more sustainable cities. Considering the strength of the relationship between the urban and rural areas, this paper offers a new perspective regarding the Rural–Urban Metabolism and its application in the Autonomous Province of Trento is discussed. The methodological approach consists of four main steps: data collection and management to support strategic territorial/urban plans; data assessment to critically evaluate the existing context; data mapping to visualize the data and territorial dynamics; and finally, the definition of the strategic and integrated development plan and actions. The Rural–Urban Metabolism proved to be a strategic approach for urban planning and design to monitor the flow of it, assess the impacts of it and promote more sustainable and circular urban policies.
