Any attempt to reverse the catastrophic consequences of climate change requires adaptation or mitigation measures. These measures can be implemented both at institutional and individual levels. For these measures to be effective, it is essential that economic agents are aware of the consequences of their decisions. This article presents the results of an activity carried out with university students to help strengthen their understanding of environmental protection. Specifically, it focuses on the implementation of a circular economy system in the textile sector. The aim is for students to gain a higher level of knowledge about the production, consumption and recycling of their clothes and discover how the circular economy can contribute to sustainability goals and the reduction of greenhouse gas emissions.
