Climate change is driving extreme weather and rising global temperatures, prompting the EU to commit to climate neutrality by 2050. While large-scale changes are vital, everyday sustainable actions—like repairing instead of replacing, recycling, composting, and buying second-hand—also play a crucial role. These habits, known as circular behaviours, are key to building a circular economy and must be nurtured from a young age. The ACCESS project supports elementary school educators in embedding these values into early education by equipping them with practical, engaging tools that raise awareness and inspire meaningful action among students. By introducing sustainability concepts through age-appropriate content, the project aims to empower the next generation to take part in the green transition.
