As COP30 underscores the urgent need for accelerated and collaborative climate action, the focus shifts to where delivery is already happening: in our cities. Across China, cities are demonstrating what this transition from commitment to implementation looks like in practice, turning national dual-carbon goals into real, on-the-ground progress.
Through a wide range of locally driven solutions such as deploying intelligent energy systems, expanding “sponge city” infrastructure, and building the world’s largest EV-charging network, Chinese cities are not only helping to meet national climate targets but also scaling solutions essential to global net-zero pathways. This series highlights how city leadership and innovation in China are shaping practical blueprints for international climate action.
