This guidance seeks to provide a concise guide to reporting on children’s rights as they relate to environmental issues. It is primarily intended to assist civil society organizations from both the human rights and environmental fields with shadow reporting for States’ periodic reviews under the Convention on the Rights of the Child (CRC). However, the guidance also provides a basis for wider uptake among other actors as well, for example for national reporting by States themselves, for international organizations such as UNICEF, and for research and academic institutions. The guidance can also be used as a resource to support reporting on children’s environmental rights within the context of other sustainable development and environmental agreements, such as the Paris Agreement and Sustainable Development Goals (SDGs), and to national accountability mechanisms such as national human rights institutions.
