We present the preliminary results of the Erasmus+ Project "NeVE Art/action", funded by the European Commission. The "NeVE Art/Action" project promoted a shared sustainable vision of Europe among teenage students in six different European countries, based on universal values such as sustainability, empathy, inclusion and participation. This aim was pursued through students' engagement in activities such as classroom readings, text writing and revision, and theatre performance, over three school years. The students performed two theatre texts based on the life and teachings of Saint Francis of Assisi, considered as an archetypal figure and precursor of fundamental European values, as an ecologist and animalist ante litteram, as well as an advocate for social inclusion, pacifism, respect for diversity and equality. In particular, we present here the results of 2 waves of a quantitative and qualitative survey, conducted respectively in the springs of 2024 and 2025, corresponding to the first and second year of the project, that monitored changes in students values and perceptions. A third wave of survey, to be conducted in spring 2026, corresponding to the final year of the project, is also ongoing. The surveys were completed by students of the six countries involved in the NeVE Art/action project: Croatia, Lithuania, North Macedonia, Portugal, Romania, Slovenia. Self-reported quantitative measures of connection to nature, sustainable consumption, empathy, tolerance, sharing, commitment, hope, and civic dedication were collected through a mobile App, at the end of each school year. Open-ended questions on inclusion and sustainability were also administered. Results (N = 356 and 337 for the first and second wave, respectively), indicate a generalized pattern of improvement in students' scores from the first to the second year of the project, in more than 60% of the indicators. The theoretical and practical implications for European and global sustainability and cohesion are discussed.
