A method to calculate the power-carbon emissions flow with the consideration of the full life-cycle carbon cost

Abstract

The proposed "double carbon" target by the Chinese government underscores the importance of reducing carbon emissions in the power industry. The power industry, whose carbon emission accounts for about 43.1% of the overall energy-related carbon emissions, is one of the Chinese largest carbon-emitting industries. Calculating the carbon emissions flow in power systems helps to better reduce the use of conventional fossil fuel and complete the "double carbon" target. This paper first analyzes the full life-cycle carbon cost from the device perspective, thus setting a boundary for carbon accounting. Then the calculation method of power-carbon emissions flow is developed. Finally, the performance of the proposed method is evaluated based on the Lishui City power system.
