Abstract :
Nowadays stakeholders and public awareness have increased the pressure on companies for
environmental issues. Thus, green supply chain management (GSCM) seems vital for companies'
environmental compliance and business growth. Companies continuously seek novel ideas and
methods, that can enable them to obtain and/or maintain environmental sustainability. Greening the
supply chain is one such innovative idea that rapidly spreads in the industry. The traditional internal
measures, such as performing waste-reduction strategies, installing pollution control technologies,
substituting hazardous-materials with environmentally friendly ones, are becoming less important as
companies strive to find more innovative solutions. Accordingly, the main objective of the present
study is to find interrelationship among green supplier criteria. For this to happen, we investigated
experts' opinions through nominal group technique (NGT) to find out the interrelationship and causal
preferences of the green supplier evaluation aspects using Decision-Making Trial and Evaluation
Laboratory (DEMATEL) method. A numerical example demonstrates the application of the proposed
model
