The relationship between climate change and children’s rights has been explicitly recognized in the 2015 Paris Agreement on Climate Change. This chapter considers how the enjoyment of children’s rights can be endangered by climate change and critically discusses the potentialities and limitations of children’s access to justice before international and regional human rights bodies to hold states accountable for their failure to protect these rights. The chapter concludes with some key challenges for states, human rights bodies, NGOs, and children themselves, suggesting, inte alia, that states should adopt a fully integrated approach toward climate policies, sustainable development, and their obligations under the Convention on Rights of the Child and that children, with the support of NGOs and other stakeholders, should fully exploit their access to justice and their participatory rights to influence decision-making on climate change that directly affects their current and future lives.
