Based on the “carbon peaking and carbon neutrality” goal, this paper combines the DSR model to build a carbon audit evaluation index system in the power industry, uses the entropy weight method to determine the index weight, and uses the TOPSIS model to calculate the effectiveness of carbon reduction and emission reduction. The research results show that from 2016 to 2020, the carbon reduction and emission reduction work in China’s power industry has achieved remarkable results, among which total profit, total reduction in soot emissions, total SO2 emissions reduction, total investment in electricity and total reduction in NOx emissions are the main factors affecting the carbon reduction and emission reduction of the power industry.
