Summary The concept of urban metabolism, referring to the exchange processes that produce the urban environment, has inspired new ways of thinking about how cities can be made sustainable and has also raised criticisms about the specific social and economic arrangements in which some forms of flow are prioritized or marginalized within the city. This article explores how the concept of urban metabolism travels across disciplines, using a comparative analysis of different approaches to urban metabolism within industrial ecology, urban ecology, ecological economics, political economy and political ecology. The analysis reveals six main themes emerging within interdisciplinary boundaries in relation to urban metabolism, and how this concept enables new understandings of (1) the city as an ecosystem, (2) material and energy flows within the city, (3) economic–material relations within the city, (4) economic drivers of rural–urban relationships, (5) the reproduction of urban inequality, and (6) attempts at resignifying the city through new visions of socioecological relationships. The article suggests potential areas for cross‐disciplinary synergies around the concept of urban metabolism and opens up avenues for industrial ecology to engage with the politics and the governance of urban development by examining the city and its metabolism.

This article traces the evolution of the eco-city as a concept and an urban planning model over the last 40 years, outlining the various definitions, applications and critiques of the term historically and today.

This article examines the international travels of ideas about sustainable urban planning and design through a focus on private sector architecture, planning and engineering consultants. These consultants, who we refer to as the global intelligence corps (GIC), package up their expertise in urban sustainability as a marketable commodity, and apply it on projects around the world. In doing so, the global intelligence corps shape norms about what constitutes ‘good’ sustainable urban planning, and contribute to the development of an internationalised travelling model of sustainable urbanism. This article draws on a broad study of the industry (GIC) in sustainable urban planning and design, and two in-depth case studies of Swedish global intelligence corps firms working on Chinese Eco-city projects. Analysis of this material illustrates how the global intelligence corps’s work shapes a traveling model of sustainable urbanism, and how this in turn creates and reinforces particular norms in urban planning practice.
