Research on Emission Factors of City-Level Power Grid: A Case of Urumqi

The context of “Carbon Peaking and Carbon Neutrality”, it has become one of the urgent demands for each local government and power consumers to account the precise indirect power emission when controlling the carbon emission, while the emission factors of power grids will directly influence the accounting result of indirect power emission. In this paper, it summarizes the status quo of emission factors of power grids at home and abroad, analyzes the disadvantages of the frequently-used emission factors of power grids in recent China and puts forward suggestions on the calculation of emission factors of city-level power grids. It also calculates the emission factor of power grid within the pilot period in Urumqi of Xinjiang Autonomous Region on the basis of real data. The calculation result indicates that the emission factor of power grid in Urumqi significantly drops in comparison to that of the region. To calculate the city-level emission factors is conducive to enhancing the accuracy of accounting result of indirect power emission, and can be used as a strong proof of the effect of energy saving and carbon reduction of the local power sector.
