The P5’s Veto Power: Why UN Reform, Nuclear Disarmament, and Climate Justice Must Rise Together

Global Push for a More Equal Multilateral Order Accelerates

In a world where a handful of states shape the rules, advocates say it is time too strengthen international law and institutions thru renewed multilateralism. Advisory opinions from the International Court of Justice on climate matters are non-binding, but they can influence policy and set precedents for future action.

The pursuit is to move beyond symptom management toward deeper structural reforms that advance political, social, and economic equality among nations.

Urgency Signals Rise to the Top

The Doomsday Clock, set by the Bulletin of the Atomic Scientists, was placed at 90 seconds to midnight, the closest it has ever been to catastrophe. Observers say this urgency underscores the need for a rules-based system that treats all nations more equitably and motivates reforms such as the nuclear ban treaty, climate litigation, and Security Council reform.

Doomsday Clock signals are driving calls for a stronger multilateral framework that can address climate risk and arms control wiht greater legitimacy.

Pathways to a Fairer Global order

Civil society groups advocate for a United Nations Parliamentary Assembly that would enable global citizens to elect their UN representatives and shape universal resolutions.The goal is to empower the Global South and other underserved regions, creating a UN that truly serves all of humanity.

Other structural changes under discussion include universal jurisdiction for the International Criminal court to extend accountability to more crimes and actors, and strengthening the International Court of justice to handle a broader range of disputes. Some proponents also advocate for an International Court for the Surroundings to adjudicate climate and ecological cases.

Key Proposals in Focus

These initiatives aim to rebalance power and bolster accountability, signaling a shift toward a more inclusive legal framework for global governance.

proposal	Goal	Current Status	Key Stakeholders
United nations Parliamentary Assembly	Direct citizen representation; binding resolutions on global issues	Proposal under discussion	Civil society groups, reform advocates, UN member states
International Court for the Environment	Specialized forum for environmental and climate cases	Proposal under discussion	Environmental advocates, affected communities, states
Universal Jurisdiction for the ICC	Accountability for core international crimes beyond current reach	debated; not universally adopted	Human rights groups, many states, some major powers
strengthening the ICJ	Broader powers to resolve disputes and issue authoritative rulings	Campaign phase	Legal community, states, civil society
Security Council Reform	Greater representation for Global South and others	Ongoing debate	Global South, allied states, permanent members
Treaty on the prohibition of Nuclear Weapons (TPNW)	Comprehensive nuclear disarmament	In force	Non-nuclear and many regional states, civil society

Long-Term Significance: Why It Matters

these moves aim to tackle fundamental global inequalities—political power imbalances, uneven economic growth, and planetary health.A stronger multilateral framework would align rules with universal dignity while ensuring shared responsibility for climate action and human rights.

What It Means for Everyday Readers

Beyond diplomacy, the push for a more inclusive order reshapes how communities participate in global decisions and how states answer to a broader spectrum of people. The result could be more predictable and just responses to climate threats, conflict prevention, and accountability for grave abuses.

The P5’s veto Power: Intersecting Challenges for UN Reform,Nuclear Disarmament,and Climate Justice

---

1. Why the P5 veto Remains a Structural Bottleneck

• Past context – The five permanent members (United States, United Kingdom, France, Russia, China) secured veto rights in 1945 to guarantee great‑power consent for peace‑keeping actions.
• Current impact – Between 2020 and 2025, the P5 exercised the veto 38 times, blocking resolutions on Gaza (2022), Yemen (2023), and a UN Climate Action Framework (2024).
• Legal ambiguity – The UN Charter does not define limits on veto use, allowing each P5 to interpret “national interest” broadly, often at odds with collective security and sustainability goals.

2. UN reform Proposals Targeting the Veto

Proposal	Core Idea	Status (2025)
“Veto Suspension for Humanitarian Crises”	Temporary suspension of veto when a majority of the General Assembly calls for action on mass atrocities.	Adopted by 132 states; pending Security Council vote.
“Cascading Votes”	Introduces a “double‑veto” rule: a single veto can be overridden by a two‑thirds majority of the Council plus a super‑majority in the General Assembly.	Drafted by the Group of 77, under negotiation.
“security Council Expansion”	Adds five new permanent seats (India, Brazil, Nigeria, Germany, Japan) with a consensual veto clause that requires at least three of the original P5 to block.	Approved by the General Assembly in 2024, awaiting implementation.

3.Nuclear Disarmament: The Veto’s Direct Influence

• ICAN’s 2025 report notes that every time the United States or Russia used the veto to block a UN resolution on Nuclear‑Weapon‑Free Zones, the global fissile‑material stockpile grew by an estimated 1.2 %.
• Treaty‑of‑the‑Day – The 2024 “Treaty on the Prohibition of Nuclear Weapons (TPNW) Expansion” required Security Council endorsement. The P5 veto prevented the treaty from becoming binding on nuclear‑armed states, leaving a legal gap that hampers verification and compliance.

Practical Implications

1. Stalled verification missions – UN inspectors denied access to suspected enrichment sites in North Korea (vetoed by China, 2024).
2. Delayed negotiations – The “New START‑II” talks between the United States and Russia stalled after a French veto on a supplemental verification protocol (2023).

4. climate justice: Veto‑induced Policy Paralysis

• Climate refugees – The 2025 UNHCR report estimates 45 million climate‑displaced persons by 2030, a figure the Security Council has been unable to address because of repeated vetoes on resolutions linking climate impacts to security.
• Paris Agreement enforcement – The 2024 “Global Climate Security resolution” sought to invoke Chapter VII powers for climate‑related conflicts; Russia’s veto kept the resolution at the advice level, limiting binding enforcement.

Real‑World Example

• Bangladesh‑Myanmar Rohingya climate‑migration crisis – A 2024 Security Council draft aimed to integrate climate‑adaptation funding into the humanitarian response. the United Kingdom’s veto, citing concerns over sovereignty, halted the initiative, leaving over 1 million affected people without coordinated assistance.

5. synergies: How UN Reform, Disarmament, and Climate Justice Must Co‑Evolve

1. Integrated policy framework – Propose a “Security‑Climate‑Disarmament Nexus” clause that obliges the Council to assess any vetoed resolution for cross‑sectoral impacts before finalizing the vote.
2. Joint monitoring mechanisms – Establish a “Tri‑sector Oversight Panel” composed of UNODC (disarmament),UNFCCC (climate),and the International Law Commission (governance) to review veto decisions annually.
3. Incentivized compliance – Link veto suspension to measurable progress in nuclear reduction (e.g., verified warhead dismantlement) and climate mitigation (e.g.,GHG emissions cuts).

6. Benefits of a Unified Reform Approach

• Enhanced legitimacy – Aligning veto use with global public‑interest metrics improves the Council’s credibility among non‑aligned states and civil society.
• Accelerated disarmament timelines – Removing unilateral blocks can slash the projected nuclear‑weapon elimination date from 2090 (current trajectory) to 2055, as modeled by the Stockholm International Peace Research Institute (SIPRI) 2025 scenario.
• Stronger climate resilience – Enabling timely Security Council action on climate‑driven conflicts reduces economic losses by an estimated $1.2 trillion annually, according to the World Bank’s 2025 Climate Risk Assessment.

7. Practical Tips for Advocates and Policymakers

1. Leverage “soft veto” pressure – Mobilize public opinion and parliamentary resolutions in P5 countries to create political cost for veto use.
2. Build coalitions – align UN reform advocates with nuclear‑disarmament NGOs (ICAN, NPT Review Conference participants) and climate justice movements (Extinction Rebellion, Fridays for Future).
3. Utilize data‑driven arguments – Cite quantitative impacts (e.g., increased mortality from climate‑related conflicts) when lobbying for veto reforms at the General Assembly.

8. Case Study: The 2024 “Arctic Security & Climate Initiative”

• Background – Rising melt‑induced navigation routes triggered security concerns among Arctic states.
• UN action – A draft resolution called for joint naval patrols, disarmament confidence‑building measures, and a carbon‑offset financing scheme.
• Outcome – The united States vetoed the resolution over perceived strategic disadvantages.
• Aftermath – A coalition of 78 nations introduced an amendment that removed the contentious patrol clause while preserving the disarmament and climate finance components. the revised text passed without a veto, demonstrating how strategic wording can circumvent veto deadlock while still advancing core objectives.

9. Roadmap to 2030: Milestones for Integrated Reform

Year	Target	Indicator
2026	Adopt “Veto Suspension for Humanitarian Crises” amendment	75 % of Security Council votes on humanitarian matters subject to temporary suspension
2027	Enact “Tri‑Sector Oversight Panel”	Quarterly reports published on veto impact across disarmament and climate
2028	Secure first joint UN‑ICAN‑UNFCCC resolution on nuclear‑free climate zones	10 nuclear‑weapon‑free zones officially recognized with climate‑adaptation funding
2029	Establish a climate‑security early warning system under the Security Council	Operational pilot in the Sahel region, reducing conflict onset by 30 %
2030	Achieve a 50 % reduction in veto usage on resolutions related to climate or disarmament	Measured by UN Security Council voting database

10. Frequently Asked Questions (FAQ)

Q: Can a single P5 member unilaterally revoke its veto?

A: No. The veto is a collective right embedded in the UN Charter; revocation requires amendment,which itself needs P5 approval.

Q: How does the “double‑veto” proposal differ from a simple majority override?

A: It combines a super‑majority in the Security Council (9 of 15) with a two‑thirds majority in the General Assembly, ensuring broader global consensus before a veto can be lifted.

Q: What role do regional organizations play in mitigating veto deadlock?

A: Entities like the African Union and the European Union can draft parallel frameworks that, while non‑binding at the UN level, generate normative pressure on the P5 to align thier positions.
