This study examines the influence of green human resource management practices mainly green rewards and green performance evaluations on the Triple Bottom Lines (environmental, economic, and social performance) of sustainability. This study looks into how these associations can be mitigated by green innovation. The data for this study was collected through a tailored questionnaire as part of quantitative analysis by using the Ministry of Education’s correspondence system which yielded 315 responses. It was established that Green awards did not significantly affect sustainability performance during examination via Structural Equation Modeling (SEM) using Smart PLS. On the other hand, Green Performance Evaluations had a positive effect. Furthermore, Green innovation largely enhances sustainable performance as well as serves as a mediator between green practices and the Ministry of Education’s objectives towards sustainability. This information is very important for both academics and practitioners since it offers valuable perceptions of what role does or can green innovation play in influencing sustainable performance.
