The purpose of this study is to discuss cause and effect relationship between the influential factors and to identify of critical success factors (CSFs) for the Green Supply chain management (GSCM) implementation in Indian automobile industries. The combined fuzzy set theory and Decision Making Trial and Evaluation Laboratory (DEMATEL) method is used, to segment the critical factors. This study visualizes the causal relationships through cause and effect diagram. The result of empirical study shows that 5 CSFs are figured out from 12 influencing factors. The finding will help to improve the effectiveness and efficiency of GSCM implementation and also provides an indication to build up an effective GSCM implementation in a stepwise manner.
