Climate risks must prompt international legal reforms

Climate Risks Must Prompt International Legal Reforms

UPSC Prelims + Mains Study Note

1. At a Glance

• Core claim: Climate change is not merely a policy challenge — it threatens to destabilise foundational principles of international law itself, including statehood, territorial sovereignty, and maritime zone demarcation. [S1]
• Three pillars of international law under stress: (i) Permanent Sovereignty over Natural Resources (PSNR), (ii) territory-based statehood criteria, and (iii) maritime zones under UNCLOS. [S1]
• The International Court of Justice (ICJ) concluded landmark hearings (Dec 2024) on states' obligations under international law regarding climate change — a watershed legal moment. [S2]
• UPSC relevance: Cuts across GS-II (International relations, multilateral bodies), GS-III (Environmental law, climate agreements) and GS-IV (ethics of burden-sharing).

2. Why in the News

• March 5, 2026: Article by Anwar Sadat, Associate Professor in International Environmental Law, Indian Society of International Law, New Delhi, published in The Hindu, argued that climate change must drive reforms to core international law principles. [S1]
• December 2024: The UN World Court (ICJ) concluded landmark hearings on states' responsibilities for climate change — initiated at the request of Vanuatu and the UN General Assembly (UNGA resolution adopted 2023). [S2]
• COP 28 (Dubai, 2023) and COP 30 (2025) raised fossil fuel phase-out language, even outside formal agendas, creating legal friction with PSNR. [S1]
• 2023 Pacific Islands Forum Declaration on Continuity of Statehood sought recognition of statehood even if island territories are submerged by sea-level rise. [S3]

3. Background & Evolution

• International Law Commission (ILC) has an active agenda item: "Sea-level rise in relation to international law" — covering statehood, maritime boundaries, and human rights. [S3]

4. Core Static Facts

Permanent Sovereignty over Natural Resources (PSNR) - Source: UNGA Resolution 1803 (XVII), 1962 — "Permanent Sovereignty over Natural Resources" - Principle: Every state has the sovereign right to freely dispose of its natural wealth including fossil fuels above and below ground - Status under climate pressure: Developing nations accept limited obligations only if not permanent and not prejudicial to their economic interests [S1]

Fossil-Fuel Non-Proliferation Treaty (FFNPT) - Concept modelled on the Nuclear Non-Proliferation Treaty (NPT) - Aims to keep large volumes of fossil fuels "unburnable" — i.e., permanently in the ground - Gaining support among scholars, Pacific Island states, and some European nations - No formal treaty yet; remains in advocacy/scholarly domain [S1]

Statehood under International Law — Traditional Criteria (Montevideo Convention, 1933) - Permanent population - Defined territory - Government - Capacity to enter into relations with other states - Problem: Small island states (e.g., Tuvalu, Kiribati) may lose defined territory to sea-level rise, potentially failing the statehood test [S3]

Maritime Zones under UNCLOS - Territorial Sea: 12 nautical miles from baseline - EEZ: 200 nautical miles - Continental Shelf: up to 350 nautical miles - Problem: Baselines are measured from low-water mark on physical coastline — rising seas shift or erase baselines, shrinking or extinguishing maritime entitlements [S3] [S4]

Key Bodies / Forums | Body | Role | |---|---| | UNFCCC / COP | Climate negotiations; fossil fuel transition language | | ICJ | Advisory Opinion on climate obligations (hearings: Dec 2024) | | ILC | Sea-level rise & international law agenda item | | Pacific Islands Forum | Statehood/maritime zone preservation declarations | | IMO | 2023 GHG Shipping Strategy | | Indian Society of International Law | Indian academic body; produced this analysis |

5. Multi-Dimensional Analysis

Environmental

• 1.5°C threshold from Paris Agreement creates legal obligation pressure to restrict fossil fuel extraction — directly conflicting with PSNR [S1]
• Sea-level rise is already measurable: IPCC projects mean sea level rise of 0.3–1 m by 2100 under high-emission scenarios, enough to submerge low-lying atolls [S4]
• Loss of land = loss of maritime zones = loss of oceanic resources (fish stocks, seabed minerals) for Small Island Developing States (SIDS) [S3]

Geopolitical / Strategic

• Fossil-fuel-dependent nations (Gulf states, Russia, Australia, Canada) resist PSNR restrictions, creating North-South and intra-developing-country fissures [S1]
• India's position: Strong adherent of PSNR and differentiated responsibilities; accepts limited obligations linked to development needs; coal-dependent economy makes sweeping PSNR limits politically untenable
• ICJ Advisory Opinion (expected ~2026) could reshape state obligations even without a new treaty — soft law hardening [S2]
• Pacific Islands increasingly ally with EU and climate-vulnerable states to push statehood continuity norms [S3]

Legal / Constitutional

• ICJ Advisory Opinion is non-binding but carries high persuasive authority and can crystallise customary international law [S2]
• Three legal principles under renegotiation: PSNR, territory-criterion for statehood, maritime zone baselines under UNCLOS Arts. 5, 7, 47 [S1] [S3]
• ILC's sea-level rise work may recommend "freezing" of baselines at pre-rise coordinates — a novel departure from UNCLOS's physical-geography basis [S3]
• A Fossil-Fuel Non-Proliferation Treaty would require states to permanently waive part of PSNR — unprecedented in treaty law [S1]
• Common Concern of Humankind doctrine (present in UNFCCC preamble) may be invoked to override PSNR in limited contexts [S1]

Economic

• SIDS face loss of EEZ fisheries and seabed resources worth billions — core livelihood and revenue streams [S3]
• Developing nations' PSNR rights underpin economic independence; phasing out fossil fuels without compensation raises just transition demands [S1]
• Loss and Damage Fund (established COP 27, operationalised COP 28) addresses economic harm but does not resolve the legal status questions [S4]

Social / Equity

• Climate refugees / stateless persons: If statehood lapses with territory loss, populations of Tuvalu, Kiribati (~100,000+ people) face statelessness under current law [S3]
• Developing country dilemma: Accept PSNR restrictions = surrender economic sovereignty; reject = bear reputational and legal costs in international forums
• Intergenerational equity — foundational concept in environmental law (Stockholm 1972, Rio 1992) — demands legal frameworks for future generations who inherit both climate damage and weakened state structures [S4]

Ethical / Governance

• Historical emissions responsibility: developed nations emitted ~80% of cumulative CO₂ yet small developing nations face territorial extinction — raises profound justice questions
• Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC) principle (UNFCCC Art. 3) must be embedded in any new legal instruments [S4]
• Scholarly writings support not imposing permanent or unconditional PSNR restrictions on developing nations without compensatory mechanisms [S1]

6. Recent Developments (Last 12–18 Months)

• Dec 2024: ICJ concluded public hearings on "Obligations of States in respect of Climate Change" — advisory opinion requested by UNGA; over 90 states and international organisations submitted written statements. [S2]
• Nov 2025 (COP 30, Belém, Brazil): Fossil fuel phase-out debated again; Fossil-Fuel Non-Proliferation Treaty advocates formally submitted treaty text for consideration outside COP agenda. [S1]
• 2025: ILC continued deliberations on "Sea-level rise in relation to international law" — second report issued by Special Rapporteur covering nationality/human rights dimensions. [S3]
• 2021–2025: Pacific Islands Forum's 2021 Declaration on Maritime Zones and 2023 Declaration on Continuity of Statehood attracted growing co-sponsorship from Caribbean, African, and South Asian states. [S3]
• 2023: IMO 2023 GHG Strategy adopted — targets net-zero emissions from international shipping by 2050, marking shipping sector's first legally relevant decarbonisation commitment. [S5]
• March 2026: ISIL (Indian Society of International Law) analysis published in The Hindu calling for systemic legal reforms — signals growing Indian academic engagement with these questions. [S1]

10. Common Errors / Trap Areas

1. PSNR ≠ absolute right today: Aspirants often treat PSNR as wholly unchallenged. In fact, UNFCCC and Paris Agreement already impose soft limitations on unfettered fossil fuel extraction. The article argues future instruments may go further.
2. ICJ Advisory Opinion ≠ binding judgment: The climate advisory opinion is persuasive, not enforceable. Confusing it with a contentious case judgment (which is binding on parties) is a common trap.
3. Loss and Damage Fund established at COP 27, not COP 28: The Fund was established at COP 27 (Sharm el-Sheikh) and its operationalisation/first pledges occurred at COP 28 (Dubai). Do not conflate.
4. FFNPT is NOT yet a treaty: The Fossil-Fuel Non-Proliferation Treaty exists as an advocacy/civil society proposal — it has not been formally adopted or signed. Treating it as existing treaty law in answers is incorrect.
5. Indian Society of International Law (ISIL) ≠ government body: ISIL is an academic/research institution in New Delhi. It is not under the Ministry of External Affairs or any government ministry. Conflating it with official Indian diplomatic positions is an error.
