At the European level, the urgency of environmental action is widely recognised, yet the psychological impact of climate change on young people remains largely unaddressed. According to the 2024 Eurobarometer survey, 67% of young Europeans consider environmental sustainability the most pressing issue of their generation, demonstrating an increasing awareness of its significance. However, another study on eco-anxiety determinants highlights that this heightened awareness is also leading to rising stress, anxiety, and feelings of powerlessness, particularly among young people constantly exposed to alarming narratives about climate change. While European policies such as the Green Deal and the European Climate Pact focus on sustainable solutions and climate mitigation, they do not directly tackle the mental and emotional burden carried by young people witnessing environmental degradation. This gap underscores the necessity for projects that not only educate on sustainability but also equip young people with emotional resilience tools, ensuring that their concerns do not lead to paralysis or despair, but rather to constructive action and creativity. The growing eco-anxiety among European youth calls for an approach that merges environmental education with psychological well-being, providing young people with alternative ways to process their concerns, transform anxiety into activism, and feel empowered to create change. At the national level, the five countries involved in the project: Italy, Poland, Bulgaria, Romania, and Spain; face distinct yet interconnected environmental challenges, reinforcing the need for transnational cooperation and collective solutions. Italy struggles with waste mismanagement and excessive water consumption, while Poland faces severe air pollution, particularly in urban areas. Bulgaria and Romania are witnessing deforestation and biodiversity loss, exacerbating environmental instability, whereas Spain is grappling with desertification and increasing water scarcity. While national governments have implemented policies and initiatives to tackle these issues, youth involvement remains limited, with many young people feeling disempowered and detached from decision-making processes. Reports from several of these countries indicate that while sustainability education exists within formal education systems, it often fails to connect emotionally with young people, leaving them with knowledge but without the necessary tools to cope with the emotional impact of climate-related challenges. This situation is further confirmed at the local level, where a questionnaire was distributed within participating communities, targeting young people aged 18-25 to understand their perceptions and personal experiences with environmental issues. The results were particularly revealing: 76% of respondents acknowledged that environmental issues directly affect their daily lives and health, demonstrating a strong awareness of sustainability concerns. However, when asked whether they experience serious issues related to eco-anxiety, 12% of young respondents stated that they suffer from significant stress and concern about the future of the planet. This finding highlights a critical need for interventions that address both environmental challenges and the psychological impact on young people, providing them with meaningful, creative, and empowering ways to navigate their emotions and actively engage in sustainability efforts. The growing need for youth-centred initiatives that merge climate education with emotional well-being reinforces the core mission of this project: to provide young people with an artistic and interactive platform where they can explore sustainability issues through creativity, transforming their eco-anxiety into constructive action and strengthening their capacity to act as proactive changemakers within their communities. Participants therefore planned the "A world breathing in EUpnea" project and set the following objectives: - To address youth eco-anxiety through art by transforming environmental concerns into creativity. - To develop participants' key and environmental competences for personal and professional growth. - To promote environmental engagement by activating young people and youth organisations in environmental protection initiatives. - To facilitate intercultural dialogue and Europeanist feeling by fostering exchange between young people within a European project.
