There is a growing body of research on the theory and practice of sustainable supply chain management (SSCM). However, relatively little research has been conducted on the extent to which corporations have integrated sustainability principles into the management of their supply chain and the evaluation of supplier performance. The purpose of this article is to explore the extent to which corporate sustainability principles are integrated into supply chain management (SCM) in corporations. Canada is used as a case study in this (...) article. The study included a content analysis of one hundred Canadian corporate sustainable development reports and in-depth interviews with 18 Canadian experts on SSCM. The article highlights the wide array of ways in which Canadian corporations address SSCM issues. Amongst other topics, issues associated with supply chain governance, standards for SSCM, collaboration with suppliers, performance measurement, and accountability within the supply chain are explored. The findings reveal that there are many challenges in integrating sustainability into SCM. These challenges shed light on possible future directions for research in SSCM. This article underlines the need for research that reflects the interconnected nature of the economic, environmental, and social dimensions of sustainability, particularly as it relates to measuring supplier performance on sustainability initiatives.
