As the world grapples with the consequences of Russia’s invasion of Ukraine, a new and unprecedented cost is being added to the ledger: climate reparations. Ukrainian authorities and international environmental economists have calculated that Russia’s military actions have generated tens of billions of euros in climate-related damage, introducing the concept of “conflict carbon”—greenhouse gas emissions caused directly by warfare.
The emerging estimate: €37 billion worth of climate damage stemming from Russia’s invasion.
This figure is not simply symbolic. It reflects a growing global movement to hold aggressor states financially accountable for the environmental and climate impacts of war—a domain long overlooked in traditional post-conflict reparations.
“Conflict carbon” refers to the greenhouse gases emitted during military operations, including:
Unlike peacetime emissions, conflict-related emissions are unplanned, uncontrollable, and massively carbon-intensive in short bursts.
The invasion of Ukraine represents the largest single conflict-related emissions event in Europe since World War II.
Environmental auditors and climate economists worked with Ukrainian ministries to quantify:
Including fuel burned by aircraft, drones, tanks, armored vehicles, trucks, and naval assets.
When infrastructure burns or collapses, massive amounts of carbon are released.
Examples include:
The war has caused:
Nature’s ability to absorb carbon has been weakened.
Rebuilding cities, housing, steel production, cement manufacturing, and logistics will produce future emissions that Ukraine argues should also be counted as climate damage caused by Russia.
Polluted land and water will require years of remediation, adding to the long-tail carbon footprint.
Combined, these categories produce the projected €37 billion climate-reparation claim.
The concept of climate reparations for war is largely uncharted territory. Traditionally, war reparations have covered:
Environmental losses were considered secondary.
Ukraine is now pioneering a new legal category:
War-driven climate damage as a billable offense.
If successful, this could transform international law and future conflict accountability.
Armies are extremely carbon-intensive.
A single fighter jet sortie can burn thousands of liters of fuel.
Thousands of such operations have occurred.
Explosions, fires, and toxic leaks have released:
These emissions dwarf those of many small countries.
The war has torched millions of hectares of land, releasing carbon stored in vegetation and topsoil.
Attacks on power grids, pipelines, and depots have created huge combustion events.
Damage to ports and river ecosystems further reduces natural carbon absorption capacities.
Kyiv’s position is straightforward:
Ukraine wants this liability recognized under:
This marks a paradigm shift in post-war accountability.
Russia rejects all forms of war reparations, including environmental ones, arguing:
But the global legal landscape is changing:
Even if Russia never voluntarily pays, compensation could be extracted from frozen Russian sovereign assets, an idea supported by multiple Western governments.
The European Union is backing Ukraine’s climate-damage claims for several reasons:
A mechanism created for Ukraine could apply to:
Europe has carbon pricing, carbon budgets, and strict emissions accounting.
War cannot be allowed to bypass these systems.
Environmental reparations add a new layer of long-term cost.
Conflict-driven emissions undermine EU climate progress and must be compensated.
If Ukraine succeeds, several global shifts may occur:
Military commanders could be held liable for:
This would add:
Especially as conflicts increasingly intersect with:
Leading to direct financial liabilities for aggressor states.
The proposed €37 billion “conflict carbon” bill is not only about monetary compensation. It represents a turning point in how the modern world evaluates war.
War is no longer judged solely by:
It is now also judged by its climate impact.
Ukraine’s push for climate reparations challenges the global community to consider a profound question:
If climate change is the greatest long-term threat to humanity, should the carbon footprint of war be treated as one of its gravest crimes?
The answer could redefine international law, reshape global conflict accountability, and set powerful new precedents for the environmental cost of aggression in the 21st century.
