Green training is considered as crucial factor in green human resource management, stimulating environmental performance in an organisation. However, the effects of environmental training on the performance of organisations in the hospitality industry have so far been under-studied. At the same time, hospitality industry in India has attracted significant attention, and therefore deserves to be studied further. This study explores the mediating effects of green competencies and proactive environmental management maturity as well as the moderating effect of environmental commitment. In order to conduct empirical analysis, a survey instrument is developed for data collection. The results indicate the following relationships: (a) a positive and significant relationship between green training and environmental performance; (b) a mediating effect of green competencies; (c) a mediating effect of proactive environmental management maturity; and (d) a moderating effect of environmental commitment. This work provides insights towards the ‘human side’ of transitioning towards sustainable hospitality management.
