The environment is the space where all living and non-living beings sustain their lives and meet their social, cultural, biological, and economic needs. For centuries, humanity has regarded nature as an unlimited resource and has overexploited it. However, recent studies show that preventing environmental problems depends once again on humans — the main actors in creating them. According to Usher et al. (2019), awareness of changing environmental conditions and the psychological distress caused by them, which worsen with rising temperatures, manifest as eco-anxiety (Hickman, 2020; Clayton, 2017). Simply put, eco-anxiety is a form of worry and distress triggered by environmental changes and our awareness of them. Today, Generation Z faces the injustice of insufficient actions taken against climate change. They see this not only as a failure to protect their own future but also as an inability to safeguard the planet and all living beings. Adopting environmental ethics plays a crucial role in achieving global success in reducing or eliminating environmental problems. For young people, prioritizing green transition and sustainability is possible only through embracing an eco-lifestyle based on altruism and environmental responsibility (Dunlap & Van Liere, 1978). Our project aimed to equip young people with the knowledge, skills, and experiences necessary to act for sustainability and environmental protection, while empowering them to value nature and take meaningful action against the climate crisis. The project’s objectives were structured under three main pillars: 1. For Participants: To encourage young people to develop environmental awareness and a strong connection with nature for their future; to highlight the importance of teamwork; to enhance intercultural learning and cooperation; and to increase the recognition of non-formal and informal education. 2. For Erasmus+ and Youth Work Practice: To support young people in developing knowledge and skills about the climate crisis and sustainability, including coping with eco-anxiety, through an ecocentric approach. To raise awareness of sustainability, promote recycling habits, and encourage urgent climate action. Participants also learned to create eco-friendly cosmetic products to reduce their carbon footprint, practiced green and sustainable agriculture, and discovered how to integrate environmental awareness into daily life. The project emphasized active citizenship, emotional resilience, and creativity through short films reflecting their role in building a sustainable future. It also promoted the recognition of Erasmus+ and the value of non-formal education. 3. For Partner Organizations: To strengthen institutional cooperation, integrate sustainability awareness into organizational strategies, increase youth participation in Erasmus+ programmes, and contribute to social and cultural development through international collaboration. Throughout the project, participants worked with strong fair play and team spirit. Ice-breaking games, intercultural evenings, group activities, and the closing event helped break prejudices and promote inclusion and equality. Diversity was celebrated, social cohesion was reinforced, and mutual understanding among young people from different cultures was strengthened. Particularly for disadvantaged youth, cooperation-based workshops improved empathy, communication, and teamwork skills. During the workshops, young participants explored topics such as environmental sensitivity, sustainability, and respect for nature. By perceiving themselves as part of nature, they developed a sense of belonging and strengthened their European citizenship identity. The project provided them with the confidence, awareness, and green competences necessary to become active changemakers in their communities and ambassadors of sustainability.
