Through the ACT Green project, we aim to respond to a pressing and growing need identified by five youth organizations across Romania, Italy, Poland, Slovakia, and Bulgaria: although young people are increasingly aware of environmental issues, they often lack the structured support, tools, and spaces to transform this awareness into action. The project’s ultimate goal is to empower youth to become informed, confident, and active contributors to environmental sustainability in their communities, and to foster their sense of European citizenship through shared intercultural learning. The project is grounded in three specific objectives, shaped by consultations with youth groups and needs assessments at local level. The first objective, O1, is to raise environmental awareness among the 25 young participants by at least 90%, through a series of structured non-formal education activities that focus on real-world ecological issues such as pollution, climate change, overconsumption, and biodiversity loss. This will be achieved through interactive workshops, participatory debates, simulation exercises, storytelling, and field visits to relevant community stakeholders. The activities are designed to help participants connect global environmental problems to their own everyday lives, communities, and cultural contexts. From a youth work perspective, this objective is not just about transferring knowledge, but about cultivating personal engagement and a mindset of responsibility and action. The learning process will be youth-led, experiential, and inclusive, with each participant actively involved in shaping discussions and proposing solutions. Young people will work in intercultural teams, explore topics through creative and reflective methods, and be encouraged to express their views, challenge assumptions, and co-create meaning. Throughout the process, youth workers and facilitators will guide participants in building critical thinking skills, understanding the complexity of environmental issues, and finding their own voice in the public conversation on sustainability. A key feature of our approach is inclusion. The group of participants includes young people with fewer opportunities, particularly those from rural or economically disadvantaged areas, where environmental education is often underdeveloped or inaccessible. For them, this project may be the first opportunity to engage with peers from other countries, explore sustainability topics in depth, and realize their potential as changemakers. Raising environmental awareness in this context is not limited to understanding facts. It includes developing empathy for the natural world, a sense of urgency, a belief in one's ability to make a difference, and the capacity to engage others. These outcomes will be supported by guided reflection, use of visual and creative tools, and follow-up evaluation through pre- and post-project self-assessment forms, ensuring that learning is tracked, recognized, and made visible through Youthpass. By the end of the exchange, we expect that at least 90% of participants will report a significant increase in their awareness of environmental challenges and a deeper understanding of sustainability as a shared European and global responsibility. This will lay the foundation for the next steps of the project: skill development and youth-led action (Objectives O2 and O3), which will build on this awareness and channel it into impactful practice. In summary, ACT Green seeks to make environmental awareness not just a topic of conversation, but a personal and collective transformation process. It does so by using youth work principles—participation, empowerment, learning by doing, and inclusion—to foster deep engagement and long-term motivation among the young people involved.
