Cities working together to lower emissions in global supply chains can be much more effective than acting alone. Seemingly unrelated cities have similar patterns of consumption-based emissions, which can form the basis of joint action designed to influence global supply chains. Stockholm, for example, has consumption patterns more like Tokyo than its neighbour Oslo.

In the case of beef, responsible for almost ten per cent of global emissions, collaboration between groups of cities across the world could lower the climate impact of their beef consumption by over 60 per cent.
