Abstract: Performance appraisal is an important means to assess employees' work performance. It serves to enhance the production competence of frontline employees through feedback in order to promote green and low-carbon development of coal enterprises. The current performance appraisal system of coal enterprises is still limited as it is mostly result-oriented, overlooking assessment on environmental protection, individual skills and learning capabilities. In this light, this study adopts the key performance indicators(KPI)method and analytic hierarchy process(AHP)in optimizing the present indicators in the performance appraisal system to highlight the "dual carbon" objective. Specifically, this study proposes environmental indicators as part of the new performance appraisal system, and suggests detailed measures to ensure its implementation.
