[5th March 2026] The Hindu OpED: Climate risks must prompt international legal reforms

Mentor’s Comment

Rising sea levels and climate-induced migration are exposing major gaps in international law, particularly regarding statehood, refugee protection, and maritime boundaries. Vulnerable small island states and forums like the Pacific Islands Forum (2023) have raised concerns that existing frameworks such as the Montevideo Convention, UNCLOS, and the 1951 Refugee Convention do not adequately address climate-driven territorial loss and displacement, prompting calls for international legal reforms.

What is Permanent Sovereignty over Natural Resources (PSNR)?

1. Concept: Permanent Sovereignty over Natural Resources (PSNR) is a principle of international law that affirms the sovereign right of states and peoples to control, use, and exploit natural resources within their territory in accordance with national development priorities.
2. Legal Origin: The principle was formally articulated in UN General Assembly Resolution 1803 (1962) on Permanent Sovereignty over Natural Resources, adopted during the decolonisation period.
3. Core Objective: Ensures that newly independent and developing countries retain control over their natural resources, preventing external exploitation by foreign powers or multinational corporations.
4. Developmental Dimension: Recognises that control over resources such as minerals, fossil fuels, forests, and water is essential for economic growth, industrialisation, and poverty reduction.
5. State Authority: Grants governments the right to regulate extraction, nationalise resources, and determine terms of foreign investment in the resource sector.
6. Climate Governance Tension: Global climate goals requiring phasing out fossil fuels create tensions with PSNR, as states traditionally retain the sovereign right to exploit hydrocarbons within their territory.
7. Relevance to Climate Debate: The emerging idea of a Fossil Fuel Non-Proliferation Treaty and discussions at COP28 and COP30 raise questions about whether global climate obligations can limit a state’s sovereign control over fossil resources.

How does climate change challenge the principle of Permanent Sovereignty over Natural Resources (PSNR)?

1. Permanent Sovereignty over Natural Resources (PSNR): Developing countries rely on PSNR to extract fossil fuels above and below ground.
2. Developmental Imperative: Enables developing states to pursue economic independence and development through resource exploitation.
3. Climate Mitigation Pressure: Global efforts to limit warming to 1.5°C require reducing fossil fuel extraction, creating tension with PSNR.
4. Fossil Fuel Non-Proliferation Treaty Proposal: Suggests keeping large portions of fossil fuels unexploited to limit emissions.
5. COP Negotiations: Discussions at COP28 (Conference of the Parties to the UNFCCC, Dubai 2023) and COP30 (Belém, Brazil 2025) indicate growing momentum toward phasing out fossil fuels, even outside formal negotiation agendas.
6. Equity Debate: Developing countries may accept limited obligations only if developed nations provide finance and transfer carbon-neutral technologies.

How does sea-level rise threaten the concept of statehood under international law?

1. Montevideo Convention (1933): Defines statehood through four criteria, territory, permanent population, government, and capacity to enter relations with other states.
2. Territorial Requirement: Statehood traditionally requires a defined territory.
3. Sea Level Rise (SLR): Rising oceans threaten to submerge low-lying island states, raising questions about whether a state can continue to exist without territory.
4. State Continuity Doctrine: Customary international law generally presumes that once established, statehood continues despite territorial loss.
5. International Court of Justice Advisory Opinion: Suggests disappearance of one element of statehood does not automatically end statehood.
6. Pacific Islands Forum (2023): Declared that international law does not yet address the extinction of states due to climate change.
7. Legal Ambiguity: Scholars note that no minimum territorial threshold exists for statehood, leaving the issue unresolved.

How does climate change create gaps in international refugee protection?

1. 1951 Refugee Convention: Defines refugees as persons fleeing persecution based on race, religion, nationality, social group, or political opinion.
2. Legal Gap: Climate-displaced persons do not fall within this definition.
3. Climate Migration: Sea-level rise and environmental degradation are expected to cause large-scale cross-border displacement.
4. Loss of Rights: Climate migrants may lose protections and benefits linked to citizenship in their home country.
5. Proposal for New Protocol: Suggests creating a separate legal regime under the UNFCCC to recognise and protect climate refugees.
6. Institutional Support: A protocol under the UNFCCC could build on political commitments from the Paris Agreement and COP negotiations.

How could sea-level rise unsettle maritime zones and ocean governance?

1. Baseline Concept: The baseline represents the legal starting point for measuring maritime zones under international law.
2. UNCLOS Maritime Zones: Baselines determine territorial sea, contiguous zone, Exclusive Economic Zone (EEZ), and continental shelf.
3. Shifting Coastlines: Rising sea levels may alter baselines, potentially changing maritime boundaries.
4. Strategic Implications: Changes in baselines may affect control over marine resources, fisheries, and seabed minerals.
5. Pacific Island States Initiative: Some states propose declaring existing baselines as permanent to prevent loss of maritime zones.
6. Ambulatory Baseline Approach: UNCLOS traditionally allows baselines to shift with coastline changes.
7. Interpretation Challenge: Accepting either approach would require reinterpretation or amendment of UNCLOS provisions.

Why must international legal frameworks adapt to climate risks?

1. Institutional Gap: Existing international law was designed without anticipating climate-induced territorial and demographic disruptions.
2. Systemic Risk: Climate change now affects statehood, migration, sovereignty, and maritime governance simultaneously.
3. UNFCCC Platform: Provides a global forum through Conference of Parties (COP) to discuss legal adaptation.
4. Equitable Governance: Legal reforms must incorporate equity, responsibility sharing, and technological support.
5. Global Stability: Updating legal frameworks ensures predictability and protection for vulnerable states and populations.

Conclusion

Climate change is increasingly exposing structural gaps in international law related to statehood, sovereignty, migration, and maritime governance. Addressing these challenges requires adaptive legal frameworks, equitable climate cooperation, and stronger multilateral coordination to protect vulnerable states and ensure stability in the evolving global order.
