Chengdu is widely recognized as a pioneer in sustainable urbanization through its ambitious Park City strategy, which aims to transform the megacity into a lush, nature-positive environment. This initiative includes the development of the Tianfu Greenway, planned to be the world's longest network of walking and cycling paths at nearly 20,000 kilometers, alongside a massive Green Belt covering approximately 188 square kilometers. The city emphasizes transit-oriented development, boasting an extensive and rapidly growing electric bus and subway network that promotes low-carbon travel and a 15-minute living circle to reduce car dependency. Additionally, projects like the Tianfu New Area serve as global exemplars of eco-friendly design, targeting significant reductions in energy and water consumption. While Chengdu still faces traditional urban challenges like air pollution and traffic congestion, its integrated approach to mapping natural assets, restoring wetlands, and incentivizing new energy vehicles demonstrates a strong commitment to becoming one of the greenest and most livable cities in the world.
