The concept of sustainability has become a buzzword in today’s business marketplace. Particularly, the incorporation of sustainability into Supply Chain Management (SCM) has received a great deal of attention from companies of all sizes and even involved a wide range of industries in recent years. Meanwhile, Sustainable Supply Chain Management (SSCM) has been highlighted by academic and corporations. With SSCM, more enterprises have benefited from being sustainable in their daily operations. Although research has made contributions, there is still a lack of understanding on how to achieve sustainable development in SCM. Therefore, the overall purpose of this research is to find out the key success factors for implementing the strategic SSCM. To achieve this target, it is necessary to identify appropriate indicators to measure the sustainable activities and figure out the relationship that combined social and environmental dimensions with supply chain activities. This research focused on Swedish global company. Both summaries of literature review and findings of the case company were analyzed to satisfy the research purpose, as a result, definition of sustainability, implementations in SSCM, and the relationship between sustainability and SCM that are based on the actual situations of the case company were presented.
