Youth workers across Europe face the same challenge: how to explain sustainability to young people in ways that are clear, visual, and hopeful. Topics like climate change, waste, or circular economy are complex, often full of jargon, and easily linked to fear or eco-anxiety. In daily practice, many youth workers avoid them or simplify them too much. At the same time, young people are asking for tools to understand what is happening in the world and how they can act. The gap is clear: youth work needs simple, visual, and engaging methods to bring sustainability into daily activities. Paint It Green (PIG) is our answer to this need. It is a 7-day E+ training course (TC) that brings together 30 youth workers (YWs) from 10 organisations (ORGs). The aim is to give them tools to use visuals, games, and clear messages to make sustainability easier to work with. The project has four objectives: 1. To build the ability of youth workers to communicate sustainability in clear, visual, and youth-friendly ways. 2. To connect daily youth work practice with the GreenComp framework and the European Training Strategy (ETS) competence model. 3. To make sustainability learning more inclusive and accessible, especially for young people (YP) with fewer opportunities. 4. To strengthen cooperation among ORGs and build a base for future European projects on sustainability and youth participation. The need for this project comes directly from partners. In surveys and focus groups, all 10 ORGs reported that their youth workers struggle with explaining sustainability, and that they lack visual, low-text methods. Many also reported that their YPs feel overwhelmed by negative news and need more hope-based approaches. The partners confirmed that now is the right moment for this project, because they want to integrate these tools into their work, but they cannot do it alone. The project follows two key frameworks: the ETS Youth Worker Competence Model and the GreenComp framework for sustainability competences. Together they give a European reference for knowledge, skills, and attitudes (K/S/A). In practice, this means youth workers will learn how to: - use sketching, icons, storyboards, and one-pagers to explain concepts; - run experiential games and simulations with clear debriefs; - design inclusive, low-text sessions that link to GreenComp values and actions; - co-facilitate in mixed teams, rotate roles, and give constructive peer feedback; - use Canva and simple digital tools to create posts, infographics, and reels that reach YP online. These competences are not abstract. They are directly linked to youth work practice. A youth worker who can draw a one-pager on recycling, run a simulation on climate trade-offs, or create a simple reel with YP, is a youth worker who is better equipped to engage young people in sustainability. The project is also designed to change daily habits inside ORGs. Each national team of three youth workers will bring back what they learn and spread it through an internal share-back for at least four colleagues. They will create a public sustainability message using visual methods. They will also co-deliver a local workshop with around 10 young people. This means that the results move beyond the participants and become part of the organisations’ regular practice. At least 100–120 YP across 10 countries will be directly reached through these local workshops. The methods themselves, with visual briefs, the Visual Sustainability Vocabulary, and workshop blueprints, will stay as tools for future sessions. The project puts inclusion at the centre. Each national team includes at least one participant with fewer opportunities. Visual methods are used not only because they are creative, but because they reduce barriers linked to language, text, or confidence. By using visuals as a common language, youth workers learn how to make participation easier for young people who usually feel left behind. In short, the project’s objective is simple: to equip youth workers with visual, game-based, and GreenComp-linked tools that they can use immediately with young people, while building habits and networks that keep these tools alive inside their organisations and beyond.
