The UN Committee on the Rights of the Child has issued new guidance emphasizing the protection of children in the face of the climate crisis. It recognizes children’s right to a clean and sustainable environment for the first time. The guidance outlines State obligations under the Convention on the Rights of the Child and holds governments accountable for both immediate and future violations of children’s rights due to climate actions or inaction. It urges countries to phase out fossil fuels, improve air and water quality, and protect biodiversity. Children’s voices and perspectives must be included in decision-making processes. The guidance is seen as a vital step towards recognizing every child’s right to a healthy and sustainable world.
