They allow the leaders and communities behind these locally-driven initiatives to feature their impact in front of an international audience, expand their outreach beyond their communities and inspire others. And they offer the chance to be closer to the local life behind the projects, around the Mayors, bringing in citizens and all relevant stakeholders contributing to foster real change. Because, in order to thrive, innovation needs inspiration. To co-create a better normal towards sustainability and embrace the transformative role of local and regional governments by learning from each other. For people and for the planet, to break through as one.
