The increased attention given to the topic of green supply chain management (GSCM) warrants the writing of this paper. The concept of
GSCM is to integrate environmental thinking into supply chain management (SCM). As such, GSCM is important in influencing the total
environment impact of any organizations involved in supply chain activities. More importantly, GSCM can contribute to sustainability
performance enhancement. In this paper, we focus on the environmental collaboration, which has been seen as a key relational capability to
facilitate the GSCM strategic formulation and execution. The purpose of this paper is two-fold: (i) review the extant literature on the
relationship between GSCM, environmental collaboration and sustainability performance and (ii) propose a plausible conceptual model to
elucidate the relationship between these three variables in the context of Malaysian manufacturing companies. Accordingly, such thought
depends upon more detailed empirical research by using advanced structural equation modeling approaches. The research findings will be
particularly important for manufacturing companies in developing environmental collaboration with their suppliers in order to achieve
sustainability performance
