Our project seeks to strengthen the role of youth workers in leading sustainable change, both within their organisations and their local communities. We want to equip youth workers with practical tools, eco-friendly methods, and a deeper sense of responsibility so they can act as credible role models for young people. At the same time, we aim to create a strong European network of NGOs that integrates sustainability into everyday practice and long-term strategy. In today’s context, where climate change and ecological crises directly affect young people’s futures, youth work cannot remain neutral. Many youth workers already recognise the urgency of environmental challenges but lack confidence or tested practices to integrate sustainability into their projects. Our objectives therefore focus on empowering youth workers to design, deliver, and follow up on youth projects in a way that reduces their environmental footprint and strengthens community awareness. Specifically, we will: - increase youth workers’ knowledge on sustainability and environmental issues and how these intersect with youth work. - provide experiential and non-formal learning opportunities to test eco-friendly methods and tools. - build participants’ competences in leadership, facilitation, project design, and digital communication, all adapted to green youth work. - nurture a personal connection to nature through outdoor and mindfulness-based activities, encouraging behaviour change that lasts beyond the project. - ensure that European values such as solidarity, responsibility, and active citizenship are reinforced, linking to the European Youth Goals on a Sustainable Green Europe. - and co-create a practical “SustainAbility Toolkit” to serve as a long-term resource for NGOs. By doing so, we expect youth workers to return to their organisations more confident, inspired, and capable of leading youth projects that align with the European Green Deal and Erasmus+ priorities. This is not only about reducing waste or changing habits during one week in Spain but also about creating a ripple effect of more sustainable youth work across eight countries.
