Core Viewpoint - The article discusses China's efforts in establishing a sustainable urban development standard system, addressing challenges in international standards, management applicability, and key technologies, while promoting China's urban governance experiences globally [1][2]. Group 1: Standard Development - China has proposed a framework for urban sustainable development standards, integrating new development concepts into management models [1]. - The "dual synchronization" model for international standard development has been innovatively established, allowing for simultaneous standard formulation and pilot verification [1]. - An example is ISO37113:2024, which provides guidelines for urban sustainable development models in response to public health emergencies, incorporating practices from various countries [1]. Group 2: Technical Innovation - The ISO37111:2024 standard has been developed to provide flexible adaptation tools for different urban areas, enhancing the international standard system for sustainable urban development [2]. - This standard supports phased implementation of sustainable development goals across various urban types, including cities, towns, and communities [2]. Group 3: International Cooperation - The standards serve as a link to deepen exchanges and cooperation between Chinese and foreign cities, such as Beijing and Tianjin with French cities [2]. - The collaboration focuses on areas like transportation, energy, and education, promoting broader and deeper shared development [2]. Group 4: Organizational Structure - A restructuring of the international standardization landscape for cities has occurred, with the establishment of ISO/IEC/JTC4 under ISO/TC268 [2]. - China is actively proposing the formation of relevant sub-technical committees to advance the development of 12 international standards and research on 10 proposals [2].
