How green human resource management affects employee voluntary workplace green behaviour: An integrated model

Green human resource management (GHRM), a set of HRM practices targeted at environmental goals, has been proposed as the key to achieving organisational sustainable development. However, the mechanisms through which GHRM influences employee green behaviour are not yet well understood. Drawing on conservation of resources theory, this study presents an integrated model revealing the mixed effects of GHRM on employees' voluntary workplace green behaviour (VWGB). Path analysis based on two studies undertaken in China largely supported our hypotheses. Specifically, GHRM was found to positively influence employees' VWGB through environmental commitment, while simultaneously decreasing their VWGB through emotional exhaustion. Meanwhile, supervisory support for environmental behaviour mitigated the impact of GHRM on emotional exhaustion as well as the relationship between GHRM and employee VWGB via emotional exhaustion. This study contributes to the GHRM literature in particular and organisational environmental management literature in general.
