4. Conclusion
This study concludes that green supply chain management encompassses potential to make
cost saving in transportation. From production firm perspective, spesifically in Turkey, main concerns
of firms are continuously tracking, controlling and thinking how to manage their all kinds of cost,
espacially transportation cost.
As mentioned in preceding sections, there is a relation as in formula mode between fuel
consumption & maintenance, repairing expenditure (FCMRE) and transportation cost. Because of the
difficulties to collect and get the transportation cost data, model has fuel consumption & maintenance,

repairing expenditure as a connection variable. This study proves the existing relation between
GSCM and FCMRE. After proving this relation and using the relation between FCMRE and TCR,
this study explains the impact of GSCM on transportation cost. Also, these research findings suggest
that green their supply chains management affect not only fuel consumption, maintenance and
repairing cost, but also through these variables affect transportation cost indirectly.
The main limitation of this study is the focus on production companies in Turkey and the lack
of study in Turkey is the powerful side of this study. The focus of this study i s o n a sample of
Turkish production companies which have ISO14001 Quality Management System.
Future research should empirically test the relationships suggested in this paper in different
countries, to enable comparative studies. A large sample would also allow detailed cross- sectoral
comparisons, which are not possible in the context of this study.
