From the perspective of life cycle assessment (LCA), the development, construction, operation of all kinds of new energy power generation technology do bring some greenhouse gas (GHG) emissions. This sparks "low carbon" property concerns of new energy power generation technology. Based on domestic and foreign relevant literature, this paper compares and estimates the GHG emission coefficients of traditional power generation and new energy power generation in China with the LCA, and then calculates the GHG mitigation potential of new energy power generation alternative to traditional coal-fired power generation, according to the national development planning objectives of new alternative energy generating. The results show that the GHG emission coefficients of new energy power generations are much lower than that of traditional coal-fired power generation even with LCA accounting, and the GHG mitigation potential of new energy substitution is still large.
