While food systems account for 25% of greenhouse gas emissions, the Eat4Climate URBACT Transfer Network, led by Mouans-Sartoux (FR) with six European partner cities, proves that food can cut down urban footprints, starting with what’s on our plates. Through the Food City Lab, local stakeholders transition toward sustainable diets, while cities transform school meals, expand local organic farming, and ensure access for all to healthy, fair, local organic food. It's not just feeding people, it's feeding the future.
