Regardless of the type of supply chain impact, businesses that undertake GSCM implement two important practices [14]. They assess the environmental performance of their suppliers and require suppliers to undertake measures that ensure the environmental quality of their products and processes. These two activities make facilities that utilize GSCM differ from most other businesses in an important way. While most other facilities seek to manage their direct environmental impacts, facilities that adopt GSCM attend to their own environmental concerns, while also seeking to affect the environmental behavior of their supplier network. As a consequence, facilities that adopt GSCM practices are anticipated to have a more far-reaching environmental strategy.
