Research on the comparative evaluation technology of carbon efficiency in the production and operation stage of overhead transmission line project based on TOPSIS method

In alignment with the national “dual carbon” goals, State Grid Corporation of China has released an action plan aimed at achieving carbon peak and carbon neutrality. This plan is designed to advance the transformation of the energy sector, speeding up the development of a clean, low-carbon, safe, and efficient energy system. The corporation is committed to continuously driving efforts to reduce carbon emissions. In this context, how to penetrate and integrate carbon measurement and investment evaluation system to realize the continuous optimization of investment decisions of power grid enterprises under the new situation has become one of the key points of power grid enterprises. Building on this foundation, this paper introduces a comparative evaluation technology of carbon efficiency in the production and operation stage of the overhead transmission line project based on TOPSIS method, which can reasonably evaluate the carbon efficiency of the operation stage, so as to support enterprises to improve the utilization level of carbon efficiency.
