Discuss the concept of 'climate justice' and examine how Indian courts have used suo motu PIL jurisdiction to address climate-induced disaster risks in the Himalayan states.

Climate justice treats global warming not merely as an environmental problem but as an ethical and rights question, placing equity and human rights at the centre of climate decision-making [4]. Indian High Courts have begun translating this idea into judicial practice in the fragile Himalaya.

The concept of climate justice

• Equity/CBDR dimension: those least responsible for emissions bear the worst harm — flood-ravaged Nepal sought compensation as a matter of principle, not charity [1].
• Distributive dimension: the UNFCCC's Fund for responding to Loss and Damage institutionalises compensation for vulnerable states [2].
• Rights dimension: in M.K. Ranjitsinh v Union of India (2024), the Supreme Court read a right against the adverse effects of climate change into Articles 21 and 14 [3].
• Participatory dimension: affected communities must have an accessible forum to shape policy balancing ecology and development [4].

Suo motu PIL and Himalayan disaster risk

• Under Article 226, High Courts act without a petitioner. The Sikkim High Court (September 2026) initiated a suo motu PIL on climate justice after the Nepal flash floods, reasoning that Sikkim's Himalayan terrain is comparably vulnerable [4].
• It issued notice to the Ministry of Railways, NHIDCL, SSDMA and the State Power Department, compelling inter-agency and Centre–State coordination otherwise absent [4].
• It invited public views and directed work on a climate-resilient road framework with BRO and NHIDCL, converting adaptation from policy rhetoric into justiciable duty [4].
• Precedent exists: after the 2023 South Lhonak GLOF, mitigation moved to the NGRMP (₹150 crore for four states) with 189 high-risk lakes identified [5].

Yet judicial activism has limits: courts lack budgets and technical capacity, funding authorities are not parties, and India still lacks a dedicated adaptation law. Judicial attention is therefore best seen as a catalyst — forcing disclosure, coordination and participation — which the executive must convert into funded early-warning systems and resilient design codes, realising the Article 21 promise the Supreme Court has already affirmed.
