Supreme Court Recognises Freedom From Climate Change as a Fundamental Right

In M.K. Ranjitsinh v Union of India, the Supreme Court of India has, for the first time, explicitly recognised that the right to be free from the adverse effects of climate change is a fundamental right under the Constitution. A Division Bench led by the then Chief Justice D.Y. Chandrachud held that Articles 14 (right to equality) and 21 (right to life and personal liberty) together confer upon every citizen the right against the adverse effects of climate change. This ruling builds on decades of environmental jurisprudence, from the early MC Mehta cases that recognised the right to a pollution-free environment, to the current expansion that specifically names climate change as a constitutional concern.

The Constitutional Basis

The ruling traces a line from the Court's earliest environmental decisions to the present. In Francis Coralie Mullin (1981), the Court held that the right to life under Article 21 encompasses the right to health, clean environment, and basic necessities. In MC Mehta v Union of India (1985), the Court recognised air pollution as a violation of the right to life and established the doctrine of absolute liability for polluting industries. Subsequent decisions expanded this to cover water pollution, noise pollution, and ecological balance. The M.K. Ranjitsinh decision goes further by explicitly connecting these precedents to climate change. The Court recognised that climate change is not a future hypothetical but a present reality that disproportionately affects vulnerable populations. By grounding this in Articles 14 and 21, the Court has placed climate protection within the enforceable fundamental rights framework rather than the non-enforceable Directive Principles of State Policy.

The Context: Great Indian Bustard Conservation

The case itself arose from a petition concerning the conservation of the Great Indian Bustard, an endangered bird species whose habitat in Rajasthan and Gujarat was threatened by overhead power transmission lines associated with renewable energy projects. The petitioners sought the undergrounding of power lines to prevent bird deaths from collisions. The government and energy companies argued that undergrounding was prohibitively expensive and would impede India's renewable energy targets. The Court had to balance the protection of a critically endangered species against the country's climate commitments, particularly its goals under the Paris Agreement. In this context, the Court articulated the fundamental right against adverse effects of climate change, recognising that both the direct threat to the bustard and the broader climate imperative engaged constitutional rights.

Implications for Environmental Litigation and Policy

The recognition of climate protection as a fundamental right has significant implications for future environmental litigation in India. Petitioners in environmental cases can now invoke this right directly under Article 32 (before the Supreme Court) or Article 226 (before High Courts) to challenge government or private actions that contribute to or fail to adequately address climate change. This could affect approvals for carbon-intensive projects, the adequacy of emission reduction targets, climate adaptation measures, and the enforcement of environmental clearance conditions. The ruling also places a positive obligation on the state to take effective action against climate change, not merely to refrain from causing environmental harm. For businesses, this means that environmental impact assessments, clearance conditions, and pollution control compliance will increasingly be viewed through a climate lens.

Practical Takeaways

Companies in carbon-intensive sectors, including energy, manufacturing, mining, and infrastructure, should reassess their environmental compliance frameworks in light of this ruling. Environmental impact assessments should explicitly address climate impacts, not just local pollution. In-house counsel and environmental advisors should monitor how lower courts and the National Green Tribunal apply this precedent in future cases. For renewable energy companies, the ruling creates a complex dynamic: while it supports the imperative for clean energy, it also requires that renewable projects themselves do not cause disproportionate environmental harm. Policy teams tracking India's climate commitments should note that this judicial development adds a constitutional enforcement dimension to what have previously been largely policy-level targets.
