The purpose of the current study is to look at how employee engagement affects the connection between environmental effectiveness and green HRM practices. Three hundred and sixty (360) workers of Ghanaian technical universities participated in the investigation, which was cross-sectional and explanatory and employed a quantitative research technique with survey questionnaires. The study's conclusions showed no meaningful correlation between environmental performance and green hiring practices. Environmental performance was, nevertheless, favorably predicted by staff green training and green appraisal. The findings also showed that the association between GHRM practices and environmental performance was not mediated by employee commitment. Human Resource Managers and Deputy Registrars overseeing human resource management should champion green HRM and create awareness of how HRM practices can increase the preservation of the natural environment in developing countries in Africa. The study offers employee perspectives on the relationship between green HRM practices and environmental performance. It also offers a paradigm for enhancing technical colleges' environmental performance via the adoption of green HRM practices.
