Urges States to take the necessary measures to ensure the full enjoyment by children of all their human rights and fundamental freedoms, and to protect them from the effects of environmental harm through effective regulation and enforcement mechanisms, including by: (a) Ensuring that the best interest of the child is a primary consideration in environmental decision-making by adopting a child rights-based approach and by recognizing the critical importance of child rights impact assessments of relevant laws, standards and policies to evaluate their actual impact on the rights of the child; (b) Committing to take precautionary action whenever there are threats of serious or irreversible damage to children from the effects of environmental harm, while noting that a lack of full scientific certainty shall not be used as a reason for postponing cost-efficient measures to prevent such threats; (c) Considering recognizing a right to a healthy environment in national legislation in order to promote justiciability, strengthen accountability and facilitate greater participation, improving environmental protection and performance and ensuring rights for present and future generations; (d) Enhancing cross-sectoral cooperation and strengthening regulatory agencies and ministries responsible for overseeing standards relevant to the rights of the child implicated by exposure to pollution, hazardous substances and wastes, climate change and the loss of biodiversity with a view to ensuring that sufficient monitoring of laws, policies and implementation mechanisms are in place to protect children from the effects of such environmental harm; (e) Strengthening efforts to monitor childhood exposure by collecting information on the impact of environmental harm on children, in particular exposure to hazardous substances, wastes and pollution, and ensuring that child-rights impact assessments take into account the ways in which environmental harm affects girls and boys differently, making such information publicly available and accessible while ensuring it is available also in ageresponsive language and formats; (f) Taking immediate and effective measures to eradicate forced labour and to secure the prohibition and elimination of the worst forms of child labour, including hazardous child labour, and putting an end to child labour in all its forms, inter alia through the enforcement of the fundamental principles and rights at work and by eliminating work by children where they are exposed to hazardous substances and wastes, while ensuring that children who have been subjected to such exposure have access to the necessary treatment and compensation; (g) Integrating gender-responsive measures into their laws, policies and programmes relevant to the protection of children from the effects of environmental harm, including by addressing sexual and gender-based violence risks; 5.
