5. Conclusions and scope of future work
Organizations all over the world are inclined towards reduction in environmental degradation based on its functioning; literature has also suggested a significant role of GHRM practices in achieving this objective. GHRM has this ability to inculcate the mindfulness among its current workforce and also encourage new recruits towards ecological improvement and wellbeing. Adopting GHRM practices instill responsibility as well as zeal among employees, train employees and evolve a learning as well open culture within the organization where employees can freely put forth their ideas and experiment towards the greening of the organization. All this results in effective utilization of resources, lesser waste generation, improved work life, improved image of the organizations and overall lesser emissions in the environment. This study identifies thirty-nine attributes of GHRM and bridges an important gap in the literature regarding lack of empirical studies and that too in a developing country. BWM is used to prioritize the GHRM practices, which is also the first study of its kind. Prioritization of GHRM practices results in important results for HR managers where green training and development is ranked as the most important GHRM practice; employees need to be trained regarding various green practices being adopted by organizations. Training in specific areas like waste management, recycling, energy management and green purchasing can greatly benefit organization to achieve environmental management goals. Moreover, HR managers need to switch to online training modules, more of digitization rather than traditional pen-paper module to save resources and also inculcate a sense of green management in employees. Employee empowerment and involvement also emerged as an important GHRM practice, employees' involvement in solving environmental problems will result in better sense of responsibility towards organizations green goals. This process will result in enhanced commitment and will also develop a new organizational culture where employees are party to each and every environmental problem. Final phase of three-phase methodology is dedicated to evaluating manufacturing organizations performance w. r.t these GHRM practices. Five organizations were involved in the study and they were ranked according to their performance on GHRM practices using Fuzzy TOPSIS. This methodology can act as a stepping stone for other organizations to measure their performance on various GHRM practices.
