The importance of sustainability for businesses is growing, as consumers increasingly consider the environmental and social impacts of their products. This shift has sparked significant interest in sustainability from an industry perspective, marking it as a megatrend in the global economy that warrants further academic exploration. This dissertation investigates the role of sustainability in the current business landscape and its influence on supply chain relationships. It highlights how integrating sustainability into these relationships affects their dynamics and structure, offering a novel methodological approach to the subject. A theoretical framework based on existing management theories is developed, detailing their insights into sustainability in supply chain management. Through both qualitative and quantitative research phases, findings reveal that sustainability and collaborative behavior in supply chain relationships positively influence one another. The manuscript presents valuable insights for research and practice, detailing theoretical and managerial implications while aligning findings with the theoretical framework. Ultimately, this work promotes the effective implementation of sustainability in supply chain management and contributes to the theoretical discourse surrounding the topic.
