This chapter aims to review recent literature on green human resources management (GHRM), outline directions for future research, and discuss implications for practitioners. In particular, the functional activities of green recruiting and selection, green orientation and onboarding, green training and development, green leadership and culture, employee involvement and participation in sustainability, green performance evaluation, green compensation, and green talent management are reviewed. These functional green HR activities are the most developed in the extant literature; they also hold the most promise for the future of GHRM as a discipline (Renwick et al. 2016). To enhance environmental performance, practitioners should perform these activities in an integrated, coherent fashion. They should also make a business case for sustainability by demonstrating the strategic role of GHRM in organisations. Research that crosses disciplinary boundaries and uses cross-cultural samples, qualitative and mixed research methods, and longitudinal time series, is needed to advance the field.
