Abstract："Coal-rich, oil-poor, gas-poor" is the basic characteristics of China's energy resources, determining the major position of coal in China's energy consumption structure, and coal itself is the highest carbon intensity of fossil fuels. Compared with the coal power industry, modern coal chemical industry can fix part of the raw coal carbon in the products, and play a role in guaranteeing national energy security. Coal to olefin is one of the main paths to achieve clean and efficient use of coal, but considering the "double carbon" goal of achieving carbon peak by 2030 and carbon neutrality by 2060, the carbon reduction of coal to olefin still needs sufficient attention. Taking a typical coal-to-olefin project in China as the research object, we analyse the energy conversion efficiency, capacity utilisation rate, total CO2 emission and CO2 emission of tonnes of polyolefin products in the past 5 years. The influencing factors of efficient energy utilisation, analyse the main paths of carbon asset management and utilisation were summarised, and the direction of green, clean and low-carbon development of the coal-to-olefin industry was discussecl.
