The city of Oslo has ambitious climate targets: reducing emissions by 95% and becoming climate resilient by 2030. Oslo’s climate strategy outlines the measures that are needed to achieve the targets. Climate mitigation and adaptation is integrated into all decision-making. To ensure that Oslo moves in the right direction, Oslo uses a climate budget to track implementation. Oslo’s climate ambition can only be achieved through a circular economy approach. Circular economy principles are already part of several of the city’s strategies, but now a more holistic plan for circular economy is being developed.
