The environment is a major global concern, and the European Union has prioritized it through the Green Deal, grounded in the principles of the Circular Economy and focused on environmental protection and climate change. Increasing environmental awareness is therefore critical, especially among youth, who will face the long-term consequences of today’s environmental challenges. This project aimed to equip participants (scout leaders) with training and tools to educate young people on environmental issues, focusing on the unsustainable use of finite resources such as water, forests, and fossil fuels. It emphasizes the harmful effects of plastic pollution—including links to climate change and potential health risks like microplastics entering the human body—and promotes the concept of reusing materials as part of the Circular Economy. Scout leaders from five countries—Malta, Turkey, Finland, Lithuania, and Georgia participated in such a project. Each country brought its unique environmental context shaped by geography, population, and economic factors. The diversity aims to enrich discussions and foster shared solutions to common problems. The project had five main objectives: 1) Understand the environmental challenges within and across participating countries. 2) Raise awareness of national environmental policies. 3) Explore practical, country-specific responses to these challenges. 4) Develop a sustainable action plan focusing on resource management. 5) Promote awareness and the sharing of good practices on both local and global levels. Given the scouts’ strong connection to nature, the project provides a fitting platform to empower leaders to involve young people in addressing environmental problems. A three-day study visit (excluding travel) brought together an average of four representatives from each participating country to each mobility. During this visit, leaders learnt how to help youth: 1) Gain skills to combat environmental issues like plastic and water waste. 2) Express and exchange their views on environmental topics. 3) Design culturally relevant, sustainable solutions. 4) Embrace greener practices such as composting and growing food. Ultimately, the initiative recognized environmental education as vital to enabling youth to actively contribute to a more sustainable future.
