Constitutionalism and environmental justice represent two of the most dynamic and intersecting fields in contemporary Indian jurisprudence. Constitutionalism, in its essence, signifies the limitation of governmental power, adherence to the rule of law, and the supremacy of constitutional values, while environmental justice emphasizes the equitable distribution of environmental benefits and burdens, ensuring that no individual or community suffers disproportionately from ecological degradation. This research paper explores the evolving relationship between the Constitution of India and the emergence of a comprehensive framework for environmental protection. It traces the historical trajectory from a pre-Stockholm phase marked by legislative inaction and minimal environmental consciousness to a transformative period of judicial awakening in the post-emergency era, during which the Supreme Court of India actively reinterpreted Directive Principles of State Policy and elevated them into enforceable Fundamental Rights, thereby reshaping the contours of Indian constitutional law. The paper critically examines the significant role of judicial activism and the development of Public Interest Litigation (PIL) as powerful tools in democratizing access to environmental justice. Through a series of landmark judgments, the judiciary has expanded the scope of Article 21 (Right to Life) to encompass the right to a clean, healthy, and pollution-free environment. In doing so, it has also incorporated key principles of international environmental law into the domestic legal system, including the Precautionary Principle, the Polluter Pays Principle, and the Public Trust Doctrine. These judicial innovations have not only strengthened environmental governance but have also ensured accountability, enhanced transparency, and encouraged public participation in environmental decision-making processes, thereby reinforcing democratic values within environmental governance. The study further engages with the constitutional challenges arising from this proactive judicial approach, particularly the ongoing debate concerning the doctrine of separation of powers and concerns of judicial overreach in policy-oriented domains. It also highlights the socio-economic dimensions of environmental justice, emphasizing the vulnerability of marginalized communities, including tribal populations, rural inhabitants, and economically weaker sections, who are often the worst affected by environmental harm, displacement, and resource depletion. Additionally, the paper examines the role of sustainable development as a guiding constitutional principle, balancing ecological preservation with economic advancement in a developing country like India. Furthermore, the research underscores the importance of institutional mechanisms and governance frameworks in ensuring effective environmental protection. It evaluates the contribution of bodies such as the National Green Tribunal in providing specialized adjudication and expeditious remedies in environmental disputes. The paper also reflects upon the growing significance of climate governance, environmental accountability, and the need for integrating scientific and technological advancements into policy formulation and implementation. Ultimately, the paper argues that environmental constitutionalism in India represents a unique, judge-driven model that has successfully bridged the gap between constitutional ideals and environmental realities. However, it underscores the necessity of evolving towards a more balanced and collaborative framework of dialogic constitutionalism, wherein the judiciary, legislature, and executive function in harmony to ensure effective and accountable governance. The paper concludes by addressing emerging challenges such as climate change litigation, recognition of the rights of nature, and the strengthening of institutional and regulatory frameworks to ensure effective, inclusive, and sustainable environmental governance for present and future generations, while reinforcing the principle of inter-generational equity and ecological balance.
