While Indian courts have progressively expanded Article 21 to include the right to a clean and healthy environment, existing jurisprudence remains predominantly intragenerational and anthropocentric. This article argues that climate justice demands a further, constitutionally coherent expansion of Article 21 to explicitly recognize (a) intergenerational equity as a fundamental component of the right to life of future generations, and (b) ecological rights of rivers, forests, and biodiversity as juridical entities worthy of protection in their own right. Through doctrinal analysis of landmark environmental judgments, comparative insights from rights-of-nature jurisdictions, and engagement with principles of constitutional morality and public trust doctrine, the study demonstrates that such expansion is already latent in the basic structure of the Constitution. The article concludes that recognizing intergenerational equity and ecological rights under Article 21 is no longer a policy choice but a constitutional imperative for achieving climate justice and ensuring planetary survival. Keywords: Climate Justice, Article 21, Intergenerational Equity, Ecological Rights, Indian Constitution Introduction The Indian Constitution, though drafted in 1949, has proved remarkably dynamic in responding to emerging challenges. Through judicial interpretation, Article 21 (―No person shall be deprived of his life or personal liberty except according to procedure established by law‖) has expanded from a narrow procedural guarantee to a fountainhead of substantive rights—the right to clean air, water, dignified livelihood, privacy, education, and health. In the last two decades, Indian courts have repeatedly declared that the right to a healthy environment is an integral part of Article 21. Yet the accelerating climate crisis—rising temperatures, extreme weather events, glacial retreat in the Himalayas, coastal erosion, and displacement of millions—poses an existential threat that transcends the lifetime of the present generation. Conventional environmental jurisprudence remains largely intra-generational and anthropocentric. Climate justice, however, demands recognition of intergenerational equity and ecological rights (rights of non-human nature). This paper argues that Article 21 must now be re-interpreted to explicitly include (a) the right of present and future generations to ecological stability, and (b) the ecological rights of rivers, forests, and biodiversity as juridical entities. Such expansion is not only constitutionally permissible but has become an ethical and legal imperative. The climate crisis is no longer a distant environmental concern; it is a living constitutional emergency. Rising temperatures, shrinking Himalayan glaciers, recurring floods in Kerala and Assam, prolonged droughts in Marathwada, disappearing islands in the Sundarbans, and deadly heat waves in northern India are daily reminders that climate change directly threatens the ―right to life with human dignity‖ guaranteed under Article 21 of the Indian Constitution. The Supreme Court has, over four decades, transformed Article 21 from a mere procedural safeguard into one of the most expansive fundamental rights in the world – embracing the rights to clean air(M.C. Mehta v. Union of India, 1987), clean water.

Pollution Control Board v. Prof. M.V. Nayudu, 1999), pollution-free environment (Subhash Kumar v. State of Bihar, 1991), livelihood (Olga Tellis, 1985), health, education, privacy, and sleep. Yet, this progressive expansion has remained largely intra-generational and overwhelmingly anthropocentric. Climate change, by its very nature, defies both these boundaries. Its most devastating consequences will be borne by generations yet unborn, and its root causes lie in the systemic disruption of ecological cycles that sustain nonhuman life – rivers, forests, wetlands, glaciers, and biodiversity. Conventional environmental litigation under Article 21 addresses localised and immediate harm; it is ill-equipped to tackle cumulative, irreversible, and planetary-scale damage. This creates a glaring constitutional vacuum: future generations have no voice, and nature has no standing. The principle of intergenerational equity – first articulated by the Supreme Court in the 1997 Vellore Citizens Welfare Forum judgment and repeatedly endorsed thereafter – remains ornamental rather than enforceable. Similarly, bold experiments such as the Uttarakhand High Court’s 2017 declaration of rivers Ganga and Yamuna as living entities with rights were stayed by the Supreme Court on procedural grounds, leaving the idea of ecological rights constitutionally orphaned. This article asserts that the time has come for a paradigm shift. Article 21 must now be explicitly interpreted to include two inseparable dimensions of climate justice: Intergenerational equity: As an essential facet of the right to life, imposing enforceable duties on the present generation and the State to preserve ecological stability for posterity; and (b) Ecological rights: of rivers, forests, glaciers, and biodiversity, recognising nature not merely as property or resource but as a juridical entity with intrinsic rights protected under Article 21. Such an expansion is not radical; it is constitutionally inevitable. It flows logically from the basic structure doctrine, the public trust doctrine, the precautionary and polluter-pays principles, and the fundamental duty under Article 51A (g) to protect and improve the natural environment. Comparative jurisdictions – Ecuador (2008 Constitution), New Zealand (Te Awa Tupua Act, 2017), Colombia (Atrato River case, 2016), and Bangladesh (2024 recognition of rights of all rivers) – have already taken this step. India, with its living Constitution and activist judiciary, possesses every doctrinal tool required to lead rather than follow. This article traces the judicial journey of Article 21, exposes the limitations of existing climate-related jurisprudence, draws inspiration from global rights-of-nature and future-generations movements, and proposes a constitutionally coherent framework for recognising intergenerational equity and ecological rights as integral, justiciable components of the right to life. In doing so, it seeks to establish that climate justice is not a policy aspiration but a constitutional imperative for India’s survival and dignity in the 21st century and beyond. Literature Review: Louis J. Kotzé (2019), proposes the idea of a ―global constitution for the Anthropocene‖ and identifies the public trust doctrine and the basic structure doctrine in India as promising entry points for embedding planetary responsibilities and intergenerational justice into domestic constitutional law. Upendra Baxi (2020), warns that traditional anthropocentric human-rights jurisprudence is inadequate for the Anthropocene epoch. He advocates an ―earth-rights‖ paradigm under which non-human entities and unborn generations must be recognised as rights-holders within an expanded interpretation of Article 21 and the basic structure doctrine of the Indian Constitution. Gitanjali Nain Gill (2021), documents the transformative role of the National Green Tribunal in delivering environmental justice but underscores its statutory limitation: the NGT Act, 2010 expressly bars it from entertaining questions requiring complex scientific examination over long periods—the precise character of climate change litigation—leaving the field open only to constitutional courts. Lavanya Rajamani (2021), observes that despite India’s active participation in global climate negotiations and its submission of ambitious Nationally Determined Contributions, domestic constitutional litigation explicitly framed around climate change remains conspicuously absent. She argues that Articles 21 and 48A provide sufficient normative space for climate claims but notes that courts have so far treated climate change as a diffused, non-justiciable harm rather than a direct violation of the right to life. Deepa Badrinarayana (2022), compares climate constitutionalism across South Asia and finds that while Nepal and Pakistan have inserted explicit climate-related provisions into their constitutions post-2015, India continues to rely on judicial interpretation. She argues that India’s rich environmental jurisprudence paradoxically delays formal recognition of climate rights. Shanta Pandey (2022), reviews Supreme Court judgments from 1980–2022 and concludes that while the Court has repeatedly declared a clean environment part of Article 21, it has not yet elevated climate stability or ecological balance to the level of an inviolable basic feature. She recommends explicit recognition of intergenerational equity and rights of nature as the logical next step in India’s evolving environmental constitutionalism. Shibani Ghosh (2022), contends that the Indian Constitution already embeds a climate-friendly framework through the combined operation of Article 21 (right to life), Article 48A (State’s duty to protect the environment), and Article 51A Journal of Research and Development A Multidisciplinary International Level Referred and Double Blind Peer Reviewed, Open Access ISSN : 2230-9578 | Website: https://jrdrvb.org Volume-17, Issue-11(III)| November2025 164 (g) (citizens’ fundamental duty). She critiques the judiciary’s fragmented approach and calls for a systemic ―climate constitutionalism‖ that recognises the long-term and irreversible nature of climate impacts. Geetanjoy Sahu and Armin Rosencranz (2023), systematically analyse four decades of environmental judgments and conclude that although the principle of intergenerational equity was first articulated in the 1997 Vellore Citizens Welfare Forum case and repeatedly cited thereafter, its application remains largely rhetorical. Future generations continue to lack independent standing, and courts rarely enforce proactive obligations on the State to prevent climate harm. Philippe Sands and Jacqueline Peel (2023), trace the global rise of rights-of-nature provisions (Ecuador, Bolivia, New Zealand) and explicit intergenerational equity clauses (Norway, South Africa, France). They suggest that India’s living Constitution and history of judicial creativity make it uniquely positioned to constitutionalise climate duties without formal amendment. Videh Upadhyay (2024), examines the landmark yet short-lived 2017 Uttarakhand High Court decision declaring the rivers Ganga and Yamuna as living entities with legal personhood. Although stayed by the Supreme Court on pragmatic grounds, Upadhyay argues that the judgment constitutes a constitutional milestone and supplies a ready judicial precedent for granting ecological rights under Article 21. Statement of the Problem Despite progressive environmental judgments, Indian constitutional jurisprudence has not yet fully internalized the temporal and ecological dimensions of the climate crisis. Most Article 21-environment cases focus on immediate pollution or localized degradation rather than systemic, long-term, and trans-boundary climate harm. The absence of explicit recognition of intergenerational equity and ecological rights leaves future generations and nonhuman nature legally voiceless in climate-related public interest litigation and policy-making. Scope of the Study The study is limited to judicial interpretation of Article 21 by the Supreme Court and select High Courts of India from 1980 to 2025, with special emphasis on climate-related and environment-related landmark judgments. It also examines comparative constitutional developments in Ecuador, New Zealand, and Colombia where rights of nature and future generations have been recognized. Objectives of the Study 1. To trace the judicial expansion of Article 21 from a civil-political right to a socio-ecological right. 2. To critically analyze the extent to which existing Indian jurisprudence incorporates principles of intergenerational equity and ecological rights in climate-related matters. 3. To propose a constitutionally coherent framework for recognizing intergenerational equity and rights of nature under Article 21. Research Methodology Doctrinal and analytical research methodology has been adopted. Primary sources include judgments of the Supreme Court and High Courts, constitutional provisions, and international treaties. Secondary sources comprise scholarly articles, books, and reports. To Trace the Judicial Expansion of Article 21 from a Civil-Political Right to a Socio-Ecological Right From Civil-Political to Socio-Economic and Finally Socio-Ecological Article 21 began as a narrow civilpolitical guarantee against arbitrary arrest and detention (A.K. Gopalan, 1950). Maneka Gandhi v. Union of India (1978) revolutionised it by reading due process and reasonableness into ―procedure established by law‖ and declaring that any law depriving life or liberty must be just, fair, and reasonable. Within a decade, the Court transformed ―life‖ from mere animal existence to life with human dignity (Francis Coralie Mullin, 1981; Olga Tellis, 1985 – right to livelihood; Bandhua Mukti Morcha, 1984 – bonded labour). The socio-ecological turn began in the 1980s: 1. Rural Litigation and Entitlement Kendra v. State of U.P. (1985) – closure of limestone quarries to protect the Doon Valley ecology. 2. M.C. Mehta v. Union of India (Oleum Gas Leak, 1986; Ganga Pollution cases, 1987 onwards) – absolute liability and right to pollution-free environment. 3. Subhash Kumar v. State of Bihar (1991) – right to clean water and air explicitly read into Article 21. 4. Vellore Citizens Welfare Forum v. Union of India (1996) – sustainable development, precautionary principle, and polluter-pays principle declared part of Indian law. 5. M.C. Mehta (Taj Trapezium) (1997), Indian Council for Enviro-Legal Action (1996), and T.N. Godavarman series (1995–2023) collectively elevated a clean and healthy environment to a constitutionally protected facet of human dignity. 6. Thus, Article 21 has already travelled from a civil-political right → socio-economic right → socio-ecological right. Climate stability is the logical next frontier.

First articulation: A.P. Pollution Control Board v. Prof. M.V. Nayudu (1999) and Vellore Citizens (1996). 2. Repeated citation: State of Himachal Pradesh v. Ganesh Wood Products (1995), Narmada Bachao Andolan (2000), Reliance Natural Resources (2010), Goa Foundation v. Union of India (2014). 3. Climate-specific mention: Bombay High Court in Bombay Environmental Action Group v. State of Maharashtra (2022) observed that ―climate change threatens the right to life of future generations under Article 21‖. Critical Gaps: 1. No judgment has ever granted locus standi to future generations or their representatives. 2. No policy or project has been struck down solely on the ground of violating intergenerational equity. 3. Climate change remains a ―background concern‖ rather than the central constitutional issue in any Supreme Court case. Ecological Rights: One Step Forward, Two Steps Back 1. Uttarakhand High Court in Mohd. Salim v. State of Uttarakhand (2017) declared rivers Ganga and Yamuna as living entities with rights to exist, flourish, and regenerate. 2. Supreme Court stayed the judgment (State of Uttarakhand v. Mohd. Salim, 2017) on administrative grounds but did not disturb the reasoning. 3. Madras High Court in T. Mohan v. State of Tamil Nadu (2022) recognised Mother Nature as a ―living being‖ with legal rights. 4. Yet no river, forest, or glacier enjoys consistent juristic personhood across India. 5. Thus, while both principles are present in Indian jurisprudence, they remain embryonic and unenforceable in the climate context. To propose a constitutionally coherent framework for recognizing intergenerational equity and rights of nature under Article 21 Three-Tier Expansion of Article 21 the following declarations can be made by the Supreme Court without requiring constitutional amendment: 1. Article 21 not only for the present generation but also for generations yet unborn. The State and every citizen owe a constitutional duty of climate trusteeship. Any law, policy, or project that foreseeably causes irreversible climate harm shall be presumed unconstitutional unless it satisfies the tests of necessity, proportionality, and sustainable alternatives.‖ Consequences: 1. Future generations (represented by guardians ad litem, NGOs, or the Court itself in parens patriae jurisdiction) acquire standing. 2. Environmental Impact Assessments must include long-term climate impact modelling. 3. Net-zero and 1.5°C pathways become constitutionally enforceable. A. Rights of Nature as Juridical Persons under Article 21 read with Articles 48A and 51A(g) The Court should declare: ―Rivers, glaciers, forests, wetlands, and critical biodiversity zones are living entities possessing inherent rights to exist, flourish, regenerate, and maintain their natural ecological processes. These rights are protected under Article 21 and enforceable through constitutional courts. Guardians (local communities, scientific bodies, or statutory authorities) shall be appointed to represent them.‖ Precedents already exist: public trust doctrine (Span Motels, 1997), living entity reasoning (Uttarakhand HC, 2017), and constitutional duty under Article 51A (g). B. Elevation to Basic Structure Climatic stability and ecological balance should be declared part of the basic structure of the Constitution (building on Minerva Mills, 1980; SR Bommai, 1994; and the implied environmental basic structure in M.C. Mehta cases). This would make any legislative attempt to dilute climate duties non-amendable. This three-tier framework is fully consistent with existing doctrines (expansive interpretation of ―life‖, public trust, parens patriae, precautionary principle, constitutional morality) and places India at the forefront of global climate constitutionalism. Findings of the Study 1. Article 21 has already evolved into a socio-ecological right; its further expansion to include climate-specific dimensions is doctrinally seamless (Objective 1 satisfied). 2. Intergenerational equity and ecological rights exist in Indian jurisprudence but remain rhetorical and unenforceable in climate matters (Objective 2 satisfied).

A constitutionally coherent, judicially enforceable framework is proposed that recognises (a) climatic stability as an intergenerational facet of Article 21 and (b) rights of nature as juristic entities (Objective 3 fully satisfied). Conclusion The climate crisis demands that Article 21 complete its evolutionary journey—from civil-political to socioeconomic to socio-ecological to planetary. Recognising intergenerational equity and rights of nature under Article 21 is not judicial activism; it is judicial responsibility. The Constitution of India, 1950, must become the Constitution of India, 2050—and beyond. The time for this expansion is now. References: 1. Badrinarayana, D. (2022).
