On November 17, 2020, a summary of the “City Emission Reduction Cooperation Project” co-sponsored by the Institute for Sustainable Development Cooperation (ISC), the National Climate Change Strategy Research and International Cooperation Center (NCSC), and the Energy Foundation (EF China) The achievement sharing meeting was successfully held in Beijing. Zeng Lei, Chief Representative of ISC China, Cao Ying, Deputy Director of NCSC Policy and Regulation Department, Lin Weiwei, EF China Low-Carbon City Project Project Manager, attended the meeting and delivered speeches from the business supervisory Chinese People’s Association for Friendship with Foreign Countries, the Pilot City Ecological Environment Bureau, and the project partner More than 50 representatives and experts from research institutions attended the meeting. At the meeting, ISC China Chief Representative Zeng Lei gave a detailed introduction to the overall implementation of the project. Representatives from 11 pilot provinces and cities including Changsha, Zhuzhou, Xiangtan, Jiyuan, Jiaxing, Jinhua, Wuzhong, Kunming, Tianjin, Zhongshan, and Guangdong shared their projects. Results and experience. Cao Ying, deputy director of the NCSC Policy and Regulation Department, Lin Weiwei, project director of the EF China low-carbon city project, Yang Xiu, associate researcher of the Institute of Climate Change and Sustainable Development of Tsinghua University, and Li Weiqi, director of the Sichuan Energy Research Institute of Tsinghua University, highly praised the project Achievements in the city’s mid- and long-term low-carbon development, peak roadmaps, and emission reductions in key urban industries, and proposed long-term strategic plans for low-carbon development, comprehensive consideration of the coordinated control of pollutants and greenhouse gases, and overall planning for economic development And recommendations on climate change work. Since the “City Emission Reduction Cooperation Project” was launched in 2017, with the joint support and efforts of all parties, the set goals of the project have been successfully completed. The pilot project involved 13 provinces, cities and regions, and 753 people from more than 20 cities participated in relevant trainings. Project achievements include carbon emissions peaking and near-zero carbon emissions in 7 provinces and cities, and medium and long-term low-carbon development research, as well as carbon emission reduction plans for key industries such as transportation, garbage classification, thermal power, and textiles in 6 cities. The first domestic publication was published. The modular design guidelines for the study of peak carbon emissions in cities provide technical and capacity building support for the work of responding to climate change in provinces and cities.
