In an era of increased stakeholder pressure for sustainable environmental management practices at workplace, organization should adopt and implement environmental ethics for seamless synergy amongst the needs of the business, the society, and the planet. Our study used resource-based view (RBV) and dynamic capabilities (DC) theoretical lenses to examine hypotheses derived from extant literature on the linkages amongst environmental ethics, environmental training, environmental performance and competitive advantage. Using survey questionnaire, we employed structural equation modeling (SEM) on 364 valid responses from managers to examine the hypotheses. The findings of our study will stir up researcher's curiosity to unravel the human side of environmental management and that will surely steer future researches in significant directions. Results suggest that environmental ethics influences environmental training, environmental performance and competitive advantage. We also found that environmental training to employees mediates the influence of environmental ethics on firm's environmental performance and competitive advantage. The findings of the study implies that organizational approach towards environmental ethical practices at workplace should be not be reactive but proactive with intentions to create and sustain synergy amongst the triads namely, profits, the society, and the environment. Environmental training should not be one-off event but a continuous process to beat competitions and improve environmental performance in the organization.
