At the professional dance conservatory of Lugo in Spain, the theme of the 2013 end-of-year show was "ecological issues". The four contemporary dance teachers worked from January to June, involving about fifty students in the project. Our aim was to understand how dance can convey concepts and/or values ​​related to various contemporary ecological issues and how the experience of dancing can potentially empower its actors. We interviewed teachers with semi-structured interviews and students with questionnaires at the beginning and at the end of the artistic mediation device. We also analyzed dance creations. Within the overall process of artistic mediation several models of mediation emerge from our analysis, all interwoven. The different mediation models provide a representation, and even up to an incarnation, of the ecological stakes which can, in some actors, trigger the desire to take action.
