The city of Oslo has taken a holistic approach to implementing circular economy (CE) principles by embedding them directly into its planning and policy documents. This systematic integration supports long-term sustainability goals and enables coordinated actions across departments. Key strategies include reducing plastic pollution, rethinking consumption, and using climate budgeting as a reporting tool for circular progress.

Like many urban centres, Oslo faced growing pressure on natural resources, increasing waste generation, and the environmental degradation of nearby ecosystems such as the Oslo Fjord. There was a need for cohesive, systemic action to address resource consumption and pollution across multiple sectors and administrative levels.

Oslo fully embedded circular economy principles into core strategic documents, including the Climate Strategy, Strategy for Future Consumption, and the Action Plan for Reduced Plastic Pollution of the Oslo Fjord. These documents guide city-level action with clear responsibilities and metrics. The Department of Environment and Transport oversees implementation, supported by technical and environmental experts, particularly in areas related to waste and resource flows. Annual reporting on CE-related measures is integrated into Oslo’s climate budget, ensuring transparency and accountability.

Oslo has established a robust governance structure for advancing circularity, demonstrating how cities can mainstream CE across planning frameworks. The integrated approach has enabled more coordinated action on waste reduction, resource efficiency, and consumption patterns, while also enhancing stakeholder involvement and monitoring through the climate budget process.

Oslo is a signatory of the European Circular Cities Declaration and contributes actively to regional circular networks such as Circular Regions. The integration supports Oslo’s goal of becoming a low-emission city by 2030.
