Today, C40 Cities is announcing new support for mayors and youth to help them co-create just solutions and work together to end our dependence on fossil fuels and ensure climate justice. C40 is running two global networks, the C40 Youth Hub and the C40 City Youth Engagement Network (CYEN). CYEN supports city officials in strengthening youth involvement in climate measures. C40 Youth Hub will bring together young people from around the world to share knowledge about urban climate solutions and empower them to promote inclusive climate action where they live. (
