Wars Fuel Climate Change: How Conflicts Are Fueling a Global Environmental Crisis

Context

A new analysis by the Climate and Community Institute (CCI) revealed that the US–Israel assault in Iran generated over 5 million tonnes of CO₂e in just 14 days, surpassing Iceland’s annual emissions. The bulk of emissions came from destroyed infrastructure, burning fuel, and combat operations.

This raises a critical question:

Are wars quietly accelerating the global climate crisis?

How Do Wars Impact the Environment?

Armed conflicts are not just political events, they are large-scale environmental disasters. From emissions to ecosystem destruction, wars leave long-lasting damage.

Direct Environmental Impacts

1. Massive Greenhouse Gas Emissions

Modern warfare is extremely carbon-intensive:

• Bombings release stored carbon
• Fuel combustion from jets, tanks, and ships adds emissions
• Burning infrastructure releases toxic gases

Example: The Iran conflict generated 5 million tonnes of CO₂e in just 14 days.

2. Destruction of Infrastructure

When cities, factories, and oil facilities are destroyed:

• Embedded carbon is released
• Toxic pollutants contaminate air, soil, and water

This creates bothimmediate and long-term environmental damage.

3. High-Emission Military Operations

Military equipment like:

• Fighter jets
• Tanks
• Naval fleets

Consume massive amounts of fossil fuels, making armed forces some of thelargest institutional emitters globally.

Indirect and Long-Term Environmental Impacts

1. Reconstruction Emissions

Post-war rebuilding involves:

• Cement
• Steel
• Energy-intensive construction

In many cases, reconstruction emits more carbon than the war itself.

2. Ecosystem Destruction

Wars damage:

• Forests
• Rivers
• Agricultural land

This leads to:

• Biodiversity loss
• Habitat destruction
• Reduced carbon absorption capacity

3. Resource Scarcity

Conflicts disrupt:

• Water supply
• Food production
• Fisheries

Result: Increasedfood insecurity and humanitarian crises.

4. Climate and Energy Shocks

Attacks on oil infrastructure and shipping routes:

• Disrupt global energy supply
• Increase fossil fuel dependence

This delays the transition to clean energy.

Case Studies: Wars and Carbon Emissions

Gaza Conflict (2025)

• 15 months of conflict → 1.9 million tonnes CO₂e
• Reconstruction → 32.2 million tonnes CO₂e
• More than annual emissions of 100+ countries

Russia–Ukraine War (2022–2025)

• Total emissions:230 million tonnes CO₂e
• Equivalent to emissions from 120 million fossil-fuel vehicles

Why This Matters

1. Missing from Climate Accounting

Military emissions are often:

• Excluded from global reporting
• Not fully regulated

This creates a major blind spot in climate policy.

2. Humanitarian and Environmental Link

Environmental damage worsens:

• Food shortages
• Water scarcity
• Health crises

Making conflicts even more devastating for civilians.

3. Threat to Global Energy Security

Conflicts in regions like theStrait of Hormuz:

• Disrupt oil supply chains
• Increase global prices

This pushes countries to rely more on fossil fuels, worsening climate change.

Conclusion

Wars are not just fought on battlefields, they are also fought against the planet.

From massive emissions to ecosystem destruction, conflicts significantly accelerate the climate crisis.

Addressing climate change without accounting for military emissions is incomplete.

For a sustainable future, global policies must:

• Include military emissions in climate frameworks
• Protect critical ecosystems during conflicts
• Promote cleaner, less destructive technologies

Because in the end, every war leaves a carbon footprint the planet cannot afford.

Featured Snippet Answers

1. How do wars affect climate change?

Wars contribute to climate change by generating large greenhouse gas emissions through fuel use, explosions, and destruction of infrastructure.

2. Why are military emissions important in climate change?

Military emissions are significant because armed forces consume large amounts of fossil fuels, yet these emissions are often excluded from global climate reporting.

3. What are the environmental impacts of war?

War causes air and water pollution, ecosystem destruction, biodiversity loss, and increased greenhouse gas emissions.

4. How does reconstruction after war affect the climate?

Reconstruction increases carbon emissions due to the heavy use of materials like cement and steel, often exceeding emissions generated during the conflict itself.

5. Why are conflicts linked to energy crises?

Conflicts disrupt oil supply chains and infrastructure, leading to higher fossil fuel dependence and delayed clean energy transitions.
