Extreme weather and failing climate policies top the list of major risks threatening the global order (WEF, 2020). It is remarkable that not the climate crisis, but the failing climate policy is mentioned. Climate policy means that democratic and political choices must be made for a sustainable future. To this end, we want to train children with Education for Sustainable Development (EDO). ESD comprises learning processes that teach students competences to consciously and actively make choices through dialogue (conversations, debate and discussion).
