ABSTRACT Today, the establishment of strong supply chain structures should be supported by a strong human resources management approach, as well as encompassing environmentalist and innovative approaches. At this point, this study has two main aims that include these requirements. The first aim is to determine whether the green human resources management (GHRM) of companies operating in the automotive industry has a direct impact on green supply chain management (GSCM). The second aim is to determine whether green product innovation (GPI) has a mediating effect in the relation GHRM and GSCM. Structural equation modelling is used to test the developed hypotheses. GHRM of automotive companies operating in Turkey has a significant positive effect on GSCM. In addition, GPI has a full mediating role in the relationship between GHRM and GSCM. Green-oriented should be establishment in the supply chain structures. Green-oriented human resources management approach is necessary to develop a green-oriented SCM. GHRM approach should be strengthened with GPI activities for GSCM.
