We explored the inspiring work of grassroots initiatives actively contributing to the green transition. We heard from representatives of these initiatives, learning how they involve citizens in their activities and what are their successes and challenges. We discussed the informal learning experiences the grassroots initiatives are facilitating, and what adult education organisations could learn from them.
