The purpose of this study is to investigate the impacts of green supply chain management (GSCM) practices on triple bottom line (TBL) measures. Fuzzy AHP is employed to reveal a relative weight of importance of each GSCM practice on TBL measures, based on inputs from twenty experts from electronic parts and component manufacturing industry. Furthermore, this study provides prioritization of enabling factors in implementing GSCM strategy from three prominent organizational theories: (i) institutional theory, (ii) resource-based view theory, and (iii) social network theory. GSCM adoption in Thai electronic industry is best explained by organization theory, where laws and regulations are the most influential factors encouraging GSCM implementation. The research study, based on findings enables recommendations for management team to allocate necessary resources in effective strategic GSCM implementations and evaluations. © 2015 IEEE.
