According to the environmental management literature, firms can realize significant cost advantage relative to competitors and improve their competitive position by implementing certain "Environmental Management Practices"(EMPs) (Hart, 1995; Shrivastava, 1995b; Christmann, 2000). Although EMPs is importance and prevailing presence, little attention has been paid to understand the drivers and outcomes of EMPs in the context of international buyer-supplier relationships. This study attempts to increase the understanding of how isomorphism pressures and organizational cultures influence the EMPs, which in turn enhance supplier’s competitive advantage in the context of international buyer-supplier relationships.
