The purpose of this study was to examine and compare what causes some municipalities to work with and market their sustainability work in circle economy and what causes some other municipalities not to do so. The study focused on six municipalities, three who worked with and marketed their sustainability work and three who didn’t. Through telephone interviews a representative from each municipalitiey answered; how they defined circular economy, what drove/not drove them to work with circular economy, what difficulties there is with circular economy in the public sector and how the municipalities work can be improved. The results showed that the definition of the economic model was about the same, what differed was their knowledge about the importance of product design. Knowledge and interest in circular economy was two of the causes of why municipalities worked with the model. The fact that the issue was not a priority and the lack of resources from politicians seemed to be two determining factors of why the municipalities’ interest in working with circular economy was small. Sweden’s government needed to act in the question and focus more on top-down instead on today’s down-top work. The municipalities needed to get guidelines and support to make decisions that promoted circular economy since it was an important part of a sustainable development.
