Considering environmental investment pressures, companies do not consider the
environmental investment to be an onerous activity. However, through this investment, they seek improvements in performance, cost savings resulting from recycling,
reuse, and environmental programs.
Customer pressure (H7) has a significant and positive influence on companies when it comes to green purchasing, driving members of the supply chain to
environmental initiatives.
Top management commitment is essential for environmental collaboration with
suppliers and to boost green purchasing, even when compared to regulatory pressure
and customer pressure (Fig. 3).
As limitations, the authors suggest the application of this conceptual model in
