Green supply chain management (GSCM) is the process of minimising the environmental impacts during various phases of supply chain. It not only integrates environmental thinking into supply chain management; from conceptualisation of product design to the delivery of final product, but also involves end of life management and reverse logistic. Thus GSCM designs the supply chain in such a manner that it should have minimum environmental footprint as well as maximum benefits in every aspect. This paper focuses on identifying critical success factors (CSF) of GSCM implementation in the automobile industry located in India. Through a detailed literature review and study we have identified 12 success factors having 42 variables. Based on this, factor and reliability analysis has been performed. These success factors are identified with exhaustive literature survey and its validation is tested using confirmative factor analysis to test the fitness of classification of elements among 12 critical success factors. The study is done in Maharashtra state of India, though the factors identified are relevant to Indian as well as global context.
