France is ahead of the game with eco-projects and green cities-Reims is a leading example. The mayor of Reims, Arnaud Robinet, has launched a series of eco-projects promoting sustainable development, making the town a leading example of a green 15-minute city. Robinet has launched the idea of 'ma ville en vert'-'green' means more than beautifying the city's green spaces but entails a better understanding of durable solutions to today's environmental crises.
