GoldGen is an innovative Erasmus+ project empowering senior citizens through education, sustainability, and digital inclusion across Europe. As the transition to a greener, circular economy accelerates, older adults are often overlooked despite their experience and potential contribution. GoldGen bridges this gap by bringing together organisations from France, Greece, Bulgaria, Portugal, and Finland to support seniors in becoming active participants in sustainable and digital societies. Through tailored learning resources, accessible training tools, and an interactive platform, the project enhances knowledge on sustainability, responsible consumption, energy efficiency, and digital skills. It also promotes active ageing, lifelong learning, and intergenerational cooperation. By developing a European curriculum, workshops, and awareness activities, GoldGen ensures inclusive participation and that no generation is left behind in Europe’s green transition.
