Since March 2022, under the guidance of the International Organization for Standardization (ISO) and the Standardization Administration of China (SAC), with the support of member cities of the International Smart Sustainable City Club (ISSCC), enterprises and research institutions, the ISO Technical Committee for Sustainable Cities and Communities (ISO/TC268), Chinese National Technical Committee for City Sustainable Development (SAC/TC567) and ISSCC jointly initiated and organized the public collection of good practices of sustainable development on carbon emission peak and carbon neutrality. The three organizations jointly established case study committee and set up working groups. After five months of collection, more than 30 cases at home and abroad were received. Through discussions among the technical group and think tank, according to the relevance of carbon neutrality, social impact and technological innovation content of the cases, after more than 10 times of field visits and nearly 20 webinars, 12 cases were finally selected and classified into cities, communities and industries (agriculture, heavy industry and service sectors). These cases has been compiled and formed this Case Collection on Sustainable Development towards Carbon Emission Peak and Carbon Neutrality 2022. This compilation is divided into five chapters of "city", "community", "heavy industry", "agriculture" and "service sector".

In Chapter I, "city", from the perspective of how cities of different sizes and from different regions can achieve the goal of carbon emission peak and carbon neutrality, three cases are included: the comprehensive transformation and development of Shenzhen as China's metropolitan and the national economic, scientific and technological innovation center; Haiyan county in the coastal area with Qinshan Nuclear Power Station in the region; the transformation of resource-exhausted city in Shanxi Province.

The Chapter II, "community", shows two cases of Sino-Singapore Tianjin Eco-city (SSTEC) and Dameisha Vanke Center dedicated to the exploration and application of new technologies on carbon neutrality.

The Chapter III "heavy industry" introduces the cases of comprehensive carbon flow management system of the State Grid Corporation of China, the Zero-carbon Industrial Park of Danfoss Haiyan Factory, and the Delingha Zhongkong Solar Power Station.

The Chapter IV "agriculture" shares the carbon neutrality path of agricultural industry from the perspective of new agriculture, and introduces of Zhongcha Company's ecological low-carbon tea garden construction and management system.

It is hoped that under the support and guidance of ISO/TC268, SAC/TC567 and ISSCC,with the careful sorting and refining by the editorial board, the most representative and innovative cases will be shared to the world through media. The case collection may provides experience for cities, communities, towns and villages, enterprises and other organizations committed to the carbon neutrality goals, and also provide the international community with pragmatic near zero carbon experience and practices in a standardized way.
