This research provides empirical evidence of a unique model that examines the relationships between green human resource management practices (GHRMPs), green innovation (GI), and environmental strategies (ES) in enhancing environmental performance (EP) in the hospitality industry. A quantitative approach using the partial least structural equation modeling (PLS-SEM) technique by SMART PLS 4 was adopted to achieve the aims of this study. The data collected by surveying 291 managers, and supervisors of 3-star, 4-star and 5-star hotels and resorts in Vietnam showed that GHRM practices (green recruitment – GR, green training and development – GTD, green reward management – GRM) had significant impacts on both green innovation and environmental performance of the hospitality business. Furthermore, it was found that green innovation acts as a mediator in the relationship between GHRMps and environmental performance. Moreover, this research has demonstrated a positive moderating effect of environmental strategies on the relationship between GHRMps and environmental performance in the hospitality industry. We introduced a new model that has proved to be effective within Vietnam’s hospitality sector. Our findings suggest that leaders and managers in hospitality organizations should recognize the value of green initiatives as a strategic asset and utilize it to accomplish their broader management objectives
