This master’s thesis delves into the inner dimension of Sustainability, aspiring to highlight the vitality of Human Values (HV) in creating durable societal change. Its purpose is to identify particular (individual and communal) values that can be vital in transformations, as well as to underline the role of Education in reinforcing them. Guiding questions for the research were the following: i) what sorts of character qualities are beneficial to be stimulated in individuals through pedagogical practices to facilitate Sustainability changes, and ii) how Education for Sustainability can contribute to achieving that mission? To answer the questions, both theoretical literature and a pedagogical application were examined. Firstly, through reviewing relevant texts focused on Human Values (HV), Environmental Ethics (EE) and Sustainability Ethics (SE). Secondly, a two–week ethnographical based research in ‘‘Arillas’’ outdoor pedagogical project on Corfu - Greece, to explore their pedagogical ethos and praxis. Aiming to frame a holistic view of the project’s pedagogical approaches, the ethnographic research was conducted with field–observations, dialogues, a video–stimulated recall with the teacher and official document investigation. Based on the ethnographic findings and the theory of Human Values developed by Shalom S. Schwartz, this study synthesizes and proposes the value framework of Eutopía, consisted by three core egoistic, altruistic and biospheric values: Autenérgeia, Synérgia and Symbíosis.
