Our chosen focus "under the umbrella" was a specific and intentional effort to encourage sustainability research at more contextually specific levels than has typically been the norm in supply chain research addressing sustainability. As scholars and practitioners increasingly recognize the importance of addressing supply chain sustainability issues, the emergent discussion in the literature has continued to evolve. Early research naturally has focused on identifying the importance of supply chain sustainability, developing definitions and frameworks for organizing our scholarly thoughts around sustainability. The extant dialogue in the literature has become rich with broad but valuable insights on the theory and practice of sustainable supply chain management.
