In China, carbon emissions from the energy and heat producing sector account for 53.4% of total emissions, with industry (28.6%) and transportation (8.9%) being the main carbon emission sectors. Therefore, various green transition policies in energy, industry and transportation are being pursued in Chinese cities. In Chinese cities, the promotion of rooftop-distributed photovoltaic power generation, among renewable energy sources, is evaluated to be capable of intensive development, reducing power peak load, and inducing residents to consume green energy. Policies are being implemented in urban industries to reduce pollution and carbon emissions, increase energy use efficiency, improve resource use levels, and improve green manufacturing systems. In the transportation sector, China's policies to reduce emissions, expand the supply of new energy vehicles, and strengthen green transportation technology are representative. Consequently, this study summarizes the policy implications, areas of Korea-China cooperation, and risk factors of China's green transition promotion plan for its Chinese cities.
