Abstract：Coal industry is the main source of carbon emissions in China,and it is of great significance to establish an evaluation index system for emission reduction and carbon reduction technologies of listed companies in the coal industry,and to evaluate the effects to achieve the goal of carbon neutrality.This study focuses on listed companies in China's coal industry,constructs an evaluation index system from the aspects of technical performance,environment,energy and economy,and evaluates listed companies' emission reduction and carbon reduction technologies through the AHP-cloud rating model.The results of the study show that:① The comprehensive score of technology evaluation shows that 75％of the listed companies' emission reduction and carbon reduction technology evaluation scores are above 0.6;② From the viewpoint of technology performance benefit index and technology environmental benefit index,there is a significant difference between listed companies,and the companies with higher scores perform better in terms of technology maturity,safety,advancement,applicability,and the emission reduction brought by the technology and the impact on the environment.The performance in terms of the technology is more excellent;③ Through the evaluation of cloud model,the evaluation of emission reduction and carbon reduction technologies of listed companies in the coal industry is in the transition from"Improveable"to"Acceptable",and is steadily moving towards"Acceptable"."This study aims to evaluate the carbon emission reduction technology of listed companies in the carbon industry from the perspective of technology evaluation.
