Quick Revision: Military activities contribute to climate change through direct emissions, destruction of carbon sinks, and disruption of environmental governance, yet remain largely unaccounted for in global climate mitigation strategies.

Why is this in the news?

The 2026 United Nations General Assembly session has underscored the persistent failure of the international community to prevent armed conflicts, which are increasingly recognised as significant contributors to climate change. Wartime activities—including the operation of military machinery, destruction of carbon-rich ecosystems, and logistical operations for arms transport—emit substantial greenhouse gases, thereby exacerbating global warming. This revelation necessitates a re-evaluation of the UN’s conflict resolution mechanisms and their integration with climate mitigation strategies.

Background

• The United Nations was established in 1945 with the primary mandate of maintaining international peace and security, as enshrined in its Charter (Article 1(1)).
• Climate change, recognised as a defining challenge of the 21st century, is governed by the United Nations Framework Convention on Climate Change (UNFCCC, 1992) and the Paris Agreement (2015), which aim to limit global temperature rise to well below 2°C above pre-industrial levels.
• Armed conflicts, particularly those of prolonged duration, result in the destruction of critical carbon sinks such as forests, wetlands, and agricultural lands, thereby reducing the planet’s capacity to sequester carbon dioxide.
• Military activities are exempt from reporting under the Kyoto Protocol’s greenhouse gas emission inventories, a provision that has drawn criticism for underestimating the carbon footprint of warfare.
• The Russia-Ukraine conflict (since 2022) has highlighted the environmental toll of modern warfare, including the burning of fossil fuels for military operations, the destruction of energy infrastructure, and the release of stored carbon from damaged ecosystems.
• The UN Security Council has, on occasion, addressed environmental degradation in conflict zones (e.g., Resolution 2375 on the Democratic People’s Republic of Korea, 2017), but systematic integration of climate and conflict agendas remains limited.

What is the relationship between armed conflict and climate change?

• Armed conflicts are a significant, yet often unaccounted, source of greenhouse gas (GHG) emissions. Military operations—including the deployment of vehicles, aircraft, and naval vessels—consume vast quantities of fossil fuels, emitting CO₂, methane, and nitrous oxides.
• The destruction of infrastructure during warfare, such as power plants, refineries, and industrial facilities, can release stored carbon and other pollutants, further contributing to atmospheric warming.
• Conflict-induced deforestation and land degradation weaken terrestrial carbon sinks. For example, the Amazon rainforest, a critical carbon sink, has faced accelerated deforestation due to illegal logging and land clearing in conflict-affected regions.
• The transport and production of weapons and ammunition involve energy-intensive processes, including mining, manufacturing, and logistics, which generate substantial GHG emissions.
• Fires set during military operations or as a result of conflict (e.g., oil well fires, urban bombardment) release black carbon and other short-lived climate forcers, which have a disproportionate warming effect in the short term.
• Prolonged conflicts disrupt agricultural systems, leading to food insecurity and increased reliance on carbon-intensive food production methods, such as synthetic fertilisers, which further elevate emissions.
• The displacement of populations due to conflict exacerbates environmental pressures in host regions, including increased demand for energy, water, and land resources, often leading to further deforestation and habitat loss.
• International legal frameworks, such as the UNFCCC and the Paris Agreement, do not explicitly address the carbon footprint of military activities, creating a governance gap in climate mitigation efforts.

Key Features

Feature	Significance
Wartime greenhouse-gas emissions	Military operations release substantial CO₂ through fuel consumption, explosions, and infrastructure destruction, exacerbating climate change.
Destruction of carbon sinks	Forests, wetlands, and other ecosystems that sequester carbon are degraded or eliminated during conflicts, reducing global carbon absorption capacity.
Arms production and transport	The lifecycle of weapons—manufacturing, deployment, and logistics—contributes significantly to emissions, often overlooked in climate accounting.
Infrastructure carbon release	Destruction of built environments releases embedded carbon from materials like concrete and steel, amplifying emissions beyond immediate wartime activities.
Post-conflict environmental degradation	Ongoing instability prevents restoration of ecosystems, leading to prolonged carbon sink loss and climate vulnerability.

Why it Matters

Environmental Governance

• Climate change mitigation strategies must integrate conflict prevention as a core component, given the disproportionate emissions from warfare.
• The UN’s inefficacy in conflict resolution directly undermines global climate goals, highlighting a governance gap in international institutions.
• Wartime emissions data is often excluded from national carbon inventories, distorting global climate accountability and policy design.

Strategic Security

• Persistent conflicts divert resources from climate adaptation and mitigation, creating a feedback loop of insecurity and environmental degradation.
• Military carbon footprints challenge the feasibility of achieving net-zero targets, particularly in regions with active or latent conflicts.
• Climate-induced resource scarcity (e.g., water, arable land) may escalate tensions, necessitating preventive diplomacy to avoid climate-security crises.

Economic Implications

• Post-conflict reconstruction imposes economic burdens, diverting funds from sustainable development and climate resilience initiatives.
• Carbon-intensive military-industrial complexes face growing scrutiny, potentially accelerating green transitions in defense sectors.
• Insurance and financial markets are increasingly factoring in climate risks associated with conflict zones, influencing investment decisions.

International Law

• Existing international humanitarian law (e.g., Geneva Conventions) lacks explicit provisions addressing environmental harm during armed conflict, creating legal ambiguities.
• The principle of ‘ecocide’ as a war crime is gaining traction, but lacks universal ratification or enforcement mechanisms.
• Climate reparations from conflict parties remain contentious, with no established framework for accountability or compensation.

Challenges

1. Gaps in Emissions Accounting

• Wartime emissions are excluded from most national greenhouse-gas inventories, leading to underreporting of global carbon outputs.
• Military exemptions in international climate agreements (e.g., Kyoto Protocol) obscure the true scale of conflict-related emissions.
• Data on emissions from arms production, transport, and infrastructure destruction is fragmented and often classified, hindering accurate assessment.

2. Institutional Weakness of the UN

• The UN Security Council’s permanent members’ veto powers paralyze decisive action on conflict prevention, despite climate-security linkages.
• The UN’s inability to enforce ceasefires or disarmament agreements undermines its credibility as a mediator in climate-vulnerable regions.
• Fragmentation between UN bodies (e.g., UNEP, UNDP, UNSC) hampers integrated responses to climate-conflict nexus.

3. Legal and Ethical Dilemmas

• The absence of a universally accepted definition of ‘ecocide’ complicates prosecution of environmental crimes during conflicts.
• Balancing state sovereignty with environmental protection in conflict zones remains a contentious issue in international law.
• Ethical questions arise over prioritizing climate action in war-torn regions where humanitarian crises demand immediate attention.

4. Resource Allocation Constraints

• Funds earmarked for climate adaptation are often redirected to military expenditures in conflict-prone states, exacerbating environmental vulnerabilities.
• Post-conflict reconstruction prioritizes infrastructure over ecological restoration, leading to long-term environmental degradation.
• Climate finance mechanisms (e.g., Green Climate Fund) face challenges in accessing conflict zones due to security and governance issues.

5. Technological and Data Limitations

• Satellite monitoring of conflict zones is often restricted, limiting real-time assessment of environmental damage (e.g., deforestation, oil spills).
• Lack of standardized methodologies for quantifying wartime emissions hinders policy formulation and international cooperation.
• Emerging technologies (e.g., AI, blockchain) for tracking emissions in conflict zones are underutilized due to geopolitical sensitivities.
