In today’s world, the link between environmental rights, sustainability and human rights is urgent. Climate change, biodiversity loss and pollution threaten ecosystems and human dignity, deepening inequalities as the most vulnerable are often hit first by heat, food insecurity and health risks. When clean air, safe water, food and shelter are compromised, basic human rights and democratic stability are also at risk. As M. Thorme observed: “Human life and the human environment are inseparable. To survive, humans must have air to breathe, water to drink, food to eat, and a place in which to live and sleep.” This link has now been formally recognised at global level: in 2021 the UN Human Rights Council affirmed the right to a clean, healthy and sustainable environment (Resolution 48/13), followed in 2022 by the UN General Assembly (Resolution 76/300). These milestones confirm that environmental rights are essential for the survival and dignity of present and future generations, yet implementation remains uneven across regions. Project aims to create a structured Training Course where participants can strengthen their knowledge of human rights and the environment, critically analyse the recognition of the right to a healthy environment and develop the skills needed to advocate for climate justice and planetary rights. The objectives of the project are: • Introduce participants to the fundamentals of human rights and their connection to the environment, exploring how environmental issues directly affect human dignity and well-being. • Raise awareness about the right to a clean, healthy and sustainable environment, examining its global recognition, current gaps in Europe and its links to other fundamental rights. • Equip participants with analytical and advocacy skills through experiential learning, enabling them to critically approach environmental issues from a human rights perspective. • Empower youth workers and youth leaders to take action by providing practical advocacy tools, strategies and participatory methods to design local initiatives and engage effectively with decision-makers. • Foster transnational cooperation and intercultural learning by creating opportunities for young people from different countries to exchange knowledge, share practices and develop joint approaches to planetary rights. • Introduce the Erasmus+ programme as a platform for promoting environmental rights, youth participation and European values, encouraging participants to use it as a tool for networking, advocacy and sustainable impact. The project is strongly aligned with the needs of the participating organisations because it directly strengthens their capacity to respond to a growing challenge in daily youth work: how to meaningfully engage young people on environmental rights, climate justice and sustainable action in a motivating, safe and practical way. Across partner countries, youth organisations increasingly face young people who are worried about environmental degradation, frustrated by slow institutional responses, and uncertain about how to take action. At the same time, many organisations lack structured methods, tested educational tools and staff confidence to address this topic beyond one-off awareness activities. This Training Course responds to these needs by equipping youth workers with ready-to-use approaches that can be integrated into regular programmes, youth centre activities, volunteering actions and community workshops.
