A socio-legal approach to children’s public participation in climate change matters warrants a comprehensive overview of the normative framework that provides this right. As one of the most affected groups by climate change impacts, children’s stakeholdership in climate change (sustainable development and environmental) governance at all levels is broadly recognised by child/youth-rights policies and international soft-law documents. Increasingly, young people themselves claim their space and voice in political negotiations, through grassroots activism or in litigation where they can influence climate action policies. Despite the widespread acknowledgement and support of children’s inclusion, there remains a considerable lack of clarity about what is actually meant by public participation in the context of children’s rights.
