Currently, cities consume 60–80% of global natural resources. They produce 50% of global waste and 75% of greenhouse gas emissions. The UN estimates that 66% of the world’s population will live in cities by 2050, while the global urban footprint will triple over the years up to 2030. Thus, cities, as a system of production and consumption, threaten global environmental sustainability. Looping actions—reuse, recycling, and recovery of resources (materials, energy, water, land, and infrastructure)—and nexus solutions can help to address resource scarcity and wastage in cities. However, there are many challenges to their implementation. In this paper, we explore these challenges. We demonstrate how context affects them and the importance of context-dependent solutions. In addition, our analysis identifies some common levers for promoting looping actions and nexus solutions in cities. View this paper
