There has been significant and increasingly rigorous and relevant research regarding sustainability in supply chains with appeal to both academics and practitioners. However, there is still much that can be learned about how to implement triple bottom line (TBL) _economic, environmental and social _ sustainability into global supply chains and networks.Much of the research on sustainable supply chains focuses on one or two of these three dimensions – for example, economic and environmental but not social sustainability _ but most does not focus on how all three dimensions work together. This chapter considers how social network analysis can provide a lens for researchers to examine sustainability across these vast global supply chains and across all three dimensions of the TBL. While there is some research that uses network analysis in exploring the TBL in global supply chains, progress to date is slow and largely conceptual. The goal of this chapter is to gauge the existing research to date on both sustainability and social networks as presented in the supply chain context. Then, avenues for future research that combine sustainability with network analysis are presented. The basic premise is to understand how social network theory can help to guide research and practice in sustainable supply chain management.
