This qualitative study explore sensemaking in communication between public procurers and suppliers in sustainable (green) public procurement. The theoretical framework comes from Weick (1995) and his theory, in the social constructivism tradition, about sensemaking in organizations, and how previous experience and previous knowledge influence employers communication and interpretation of it. A definition of sensemaking is: “basic evolutionary process in which retrospective interpretations are built during interdependent interaction” (Weick et al, 2005, page 413). Data was obtained through interviews with four public procurers and four suppliers. The method was to analyze sensemaking and keywords and themes in the interviews through Weicks theory and method and the ladder of analytical abstraction to answer: How do public procurers and suppliers make sense of sustainable public procurement in their communication during procurement? The findings say that a lot of sensemaking activity, internal and external, is about how to create opportunity for communication within the restricted legal context. What affects sensemaking in communication is how sustainability would be proven and how the stakeholders can trust each other. The findings suggest that a communication with more oppenness and less insecurity would lead to less misunderstanding, misinterpretation and better public procurement deals and more sustainability. Researchers suggest more studies about sensemaking in ordinary worklife, like this one. Further research could be a case study of direct communication between public procurers and suppliers in a meeting, where context take more place - or a larger study.
