Environmental Constitutionalism and the Recognition of the Right to a Healthy Environment

Abstract

Environmental constitutionalism has emerged as one of the most significant developments in contemporary constitutional law, reflecting the growing recognition that environmental protection is essential for the realization of fundamental human rights. As climate change, biodiversity loss, pollution, deforestation, and environmental degradation increasingly threaten human life and sustainable development, many nations have incorporated environmental rights and duties into their constitutions. The recognition of the right to a healthy environment as a fundamental human right has strengthened judicial review, promoted governmental accountability, and enhanced public participation in environmental governance. International developments, including the 2022 United Nations General Assembly Resolution recognizing the right to a clean, healthy, and sustainable environment, have further reinforced constitutional commitments toward environmental justice. This paper critically examines the evolution of environmental constitutionalism through international legal frameworks, comparative constitutional practices, and landmark judicial decisions. It analyzes the constitutional recognition of environmental rights in countries such as India, South Africa, Brazil, Ecuador, Colombia, and France while evaluating the role of constitutional courts in enforcing environmental obligations. The study further explores contemporary legal challenges relating to climate change litigation, intergenerational equity, sustainable development, environmental governance, indigenous rights, and ecological justice. Finally, it proposes future constitutional and legislative reforms aimed at strengthening environmental democracy, ensuring effective implementation of environmental rights, and promoting sustainable development for present and future generations.
