The purpose of this study is to develop employee performance indicators based on Green HRM, quantitatively test the influence of Green HRM implementation on employee performance and answer black box that explain how the implementation of Green HRM can improve employee performance through the effect of mediation role (Organizational Identification) and moderation (Perceived Organizational Support).The sample of this research is 90 respondents from six state universities in Central Java Province with simple random sampling technique. Implementation of Green HRM is not only needed in the business world only, but also in education that has committed to implement environmental management system in its business process. The result of this study indicates that employee performance indicators based on Green HRM are formed from policies that support green behavior and green health in the office and also waste management policies. This research also supports the result that the implementation of Green HRM can increase the sense of ownership of employees in the organization that ultimately can improve its performance. However, the role of moderation was not significantly supported. This means that organizational support for successful implementation of Green HRM is not very necessary as long as employees understand the organization's identity well. Suggestions for this study are, although the organizational support is not proven to moderate the successful implementation of Green HRM on the high organizational identification perceived by employees, but organizational support is still needed to support employee performance.
