Cities in the Alliance


Having faced environmental, economic and social crises, industrial legacy cities are champions in reinventing themselves and turning challenges into opportunities. The Urban Transitions Alliance will be guided by their joint vision of well-managed transitions towards a sustainable future, which centers on a healthy environment and just opportunities for their citizens.

These cities are working together to achieve sustainable urban transitions
