In September 2020, the Chinese government proposed carbon peak and carbon neutral targets at the 75th UN General Assembly. The vision of "Achieving Carbon Neutrality by 2060" will have a profound impact on the transformation of China"s energy structure. The CHINAGEM model is used to simulate and analyze the current policy scenario (baseline scenario) and carbon neutral scenario (policy scenario), and predict China’s energy development status from 2020 to 2040, including the total primary energy consumption, terminal energy consumption, and electricity generation and their composition. Based on the results of the analysis, this article puts forward the phased goals of achieving various macro indicators in the short and mid-term under the overall goal of China's carbon neutrality.
