[0002] Electricity carbon emission trajectory analysis is a process used to evaluate the relationship between the power system and carbon emissions. It involves multiple aspects, including the energy structure of power production, technology selection, policy orientation, and economic and environmental factors. Scientific methods and technical means are needed to conduct electricity carbon emission trajectory analysis.
