How War Is Accelerating Climate Change — An Unexpected and Urgent Crisis

War and climate change—two issues that often seem separate—are now more interconnected than ever before. While many assume that wars only cause destruction of lives and property, recent insights reveal that their environmental impact is equally devastating, if not more so. This blog explores how modern conflicts are fueling climate change, transforming what we think of as “collateral damage” into a global environmental crisis.

The Hidden Environmental Toll of Modern Warfare

Most of us are familiar with the tragic human and economic costs of war—loss of lives, displacement, destruction of infrastructure. But what many overlook is the environment’s suffering during conflicts. Today’s wars involve heavy use of weapons, explosives, and military machinery that cause direct damage to ecosystems. But more subtly, they set off a chain reaction of environmental harm through various channels:

• Explosive and Weapon Usage: Explosives and weapons release massive amounts of carbon dioxide (CO2) directly into the atmosphere. For instance, the ongoing conflict in Gaza has emitted approximately 33 million tons of CO2 so far—a figure comparable to the emissions from millions of petrol-powered cars. Similarly, the Ukraine conflict has released nearly 300 million tons of CO2—about the same as France’s annual emissions.

• Destruction of Infrastructure and Resources: War damages energy infrastructure, leading to increased reliance on fossil fuels for recovery and military operations. The conflict zones become hotspots for environmental degradation, with oil tankers and military equipment contributing to pollution and emissions.

• Burning of Fires and Flares: During conflicts like the Gulf War of 1990, fires ignited in oil fields burned for months, releasing hundreds of millions of tons of CO2. These fires also generate black carbon (soot), which worsens air quality and accelerates global warming.

Climate Casualties: War as an Environmental Crisis

The impact of war on climate change is not just about emissions during active conflicts. It’s about the long-term, cumulative damage:

• Carbon Footprint of War Zones: The environmental damage caused by conflict zones adds to global greenhouse gases, pushing climate change further. For example, the “Harmous” situation in West Asia involves oil tankers passing through dangerous areas, increasing the risk of spills and pollution that affect climate and health.

• Black Carbon and Air Pollution: Black carbon, a particulate matter from soot, is a significant contributor to climate change and health problems. War-related fires and explosions intensify black carbon emissions, which settle on ice and snow, accelerating melting and rising sea levels.

• Environmental Repercussions of Explosive Devices: The use of explosives releases chemicals and particulate matter that linger in the atmosphere, affecting air quality and contributing to global warming.

The Ripple Effect: War’s Impact on Global Climate Policies

The environmental damage from war doesn’t stay contained within conflict zones; it ripples across the globe:

• Reversal of Decarbonization Efforts: Countries like those in the European Union, which have been leading the push towards decarbonization, are now forced to backtrack. Due to the energy demands of war, nations are reactivating coal plants or relaxing environmental norms to ensure energy security.

• Rise of Fossil Fuel Use: Increased demand for energy in wartime—whether for military operations, rebuilding, or maintaining supplies—leads to greater reliance on fossil fuels, further fueling climate change.

• Shift Toward Electric and Sustainable Technologies: Ironically, conflict zones are also pushing the adoption of cleaner technologies, like electric vehicles and renewable energy, as part of efforts to reduce dependence on fossil fuels. However, the overall trend remains dominated by increased emissions.

Why Does This Matter?

Understanding the environmental impact of war is crucial because it reveals a hidden, long-term threat to our planet. Climate change is often discussed in terms of industrial emissions and deforestation, but conflict-induced emissions are an urgent and often overlooked contributor. As wars become more destructive and frequent, their cumulative environmental toll can undo decades of climate action.

Moreover, climate change itself can act as a catalyst for conflicts—creating a dangerous cycle where wars worsen climate risks, which then lead to more conflicts driven by resource scarcity, migration, and economic instability.

What Can We Do?

Recognizing the link between war and climate change underscores the importance of peace and stability—not just for human security but for planetary health. Advocating for conflict resolution, peace-building, and international cooperation can help mitigate some of these environmental damages.

At the same time, policymakers need to integrate environmental considerations into conflict zones—ensuring that war efforts minimize ecological destruction and that post-conflict recovery prioritizes sustainable practices.

Conclusion: War and Climate—A Hidden Crisis

The facts are startling: modern warfare is contributing significantly to climate change through direct emissions, destruction of ecosystems, and increased reliance on fossil fuels. As conflicts continue to escalate worldwide, their environmental footprint threatens to accelerate global warming, making it even harder to meet climate goals.
