This paper evaluates an approach for strengthening environmental rights for children to safeguard child health. We focus on children as beneficiaries of environmental rights on account of their vulnerability to environmental impacts on their physical and mental health. Current legal frameworks, unless explicitly identifying children as beneficiaries, arguably tend to be adult-centric. Our goal here is to develop a comprehensive rights-based framework to ensure that children are protected against adverse environmental impacts. We argue that approaches that safeguard children’s rights to life, health, and education should include environment-related issues, standards, and protections for those rights to be fully implemented. We propose employing sustainable development as a framework under which to develop an international treaty to promulgate the environmental rights of the child, thereby promoting health, environmental stewardship, and quality of life for children and future generations. We further argue that children’s environmental rights extend beyond basic “needs”—such as clean air, clean water, sanitation, and a healthful environment, among others—to include the right to benefit from access to nature of a certain quality and the wealth of educational, recreational, developmental, and health benefits that come with ensuring protection of the environment for children.
