In the modern corporate landscape, the significance of incorporating sustainability in the organization's strategic approach and operating strategies is being understood. Integrating human resource policies and practices into environmental sustainability goals, Green Human Resource Management (GHRM) has become a crucial strategy. This study explores the relationship between Green Human Resource Management (GHRM) practices and environmental sustainability and organizational sustainability. Research will examine important GHRM practices – such as green recruitment and selection, green training and development, green performance appraisal, green compensation and reward, and employee involvement in green activities. To examine the effects of these practices on employees' eco-related attitudes, actions, resource conservation, and organizational sustainability outcomes, a quantitative research approach was used. This study analyzes the connection between GHRM activities and various organizational performance measures like process efficiency, employee participation, company image and long-term competitiveness. The results show that successful practices of GHRM can play an important role in achieving environmental sustainability by supporting the use of resources in a responsible way and minimize the organization's environmental impact. In addition, GHRM can positively impact organizational sustainability by promoting employee engagement, productivity and better alignment with organizational sustainability objectives. The research underscores the significance in applying sustainability principles in HRM practices and will be useful to managers, policy makers and researchers who wish to implement sustainable organizational development in the business world in this environment of growing environmental awareness
