F-35s, fixing and fires: Ukraine, Gaza Wars threaten climate

Climate damage: Russia must pay!

Rebuilding Gaza will increase emissions

Massive gaps in military emissions data

Researchers estimate that the first three years of the conflict generated 237 million tons of greenhouse gasses (GHG). This is equivalent to the annual emissions of Belgium Austria and Ireland combined or 120 million cars running on fossil fuels.

This is pushing us into the wrong direction, at a time we need to drastically cut emissions," said Lennard de Klerk of Climate Research, the lead author of a report that tallied the war's emission, published in this month.

De Klerk stated that the cost of climate damage due to the war, in which hundreds and thousands of people were killed on both sides, already exceeded $43 billion.

When post-conflict rebuilding is taken into account, a separate study on the Israeli-Hamas conflict in Gaza estimated the carbon footprint of the first 15 month's war topped 32 millions tons.

This is equivalent to the annual emissions from Ivory Coast.

Benjamin Neimark led the research of UK and U.S. based experts.

The projected reconstruction emissions were a real shock. This was a shocking revelation and it made us sit up.

The groundbreaking studies will be presented at the sidelines next month's COP30 Climate Summit in Brazil.

Researchers say that conflicts and climate changes create a destructive cycle. Not only do wars cause climate change but climate change also fuels conflict in fragile areas as the competition for water and other resources intensifies.

WILDFIRES

De Klerk was surprised that wildfires accounted for a fifth (of the war's) carbon footprint after Russia's invasion in 2022.

Unrelenting shelling caused thousands of fires that ravaged farmland and forests. Some of these fires were likely made worse by landmines or unexploded ordnance scattered across the landscape.

According to the report of the Initiative on GHG Accounting of War (an international research team headed by de Klerk), nearly 850,000 hectares of land were burned last year.

He said that the amount of rain was more than 20 times higher than the average annual rainfall. The summer of 2024, due to climate changes, was exceptionally dry. This allowed fires to spread.

As the Gaza war expanded, missile attacks across the Lebanon-Israel frontier also caused fires that destroyed forests and farmland.

Firefighters in war zones face many dangers, as in Ukraine.

RECONSTRUCTION

Emissions have also increased due to the destruction of energy infrastructure both in Ukraine and Gaza.

The Russians' attacks on oil depots have caused tons of fuel to burn, and the gas and electricity infrastructure has released powerful GHGs such as methane or sulphur-hexafluoride (SF6) which has a potential global warming 24,000 times higher than CO2.

Solar panels provided a quarter (one of the largest shares) of Gaza's electricity before Israel attacked the enclave in October 2023.

The destruction of solar infrastructure has led to a greater reliance on diesel generators, which are polluting.

Neimark stated that the carbon footprint from post-war reconstruction of Gaza, which has seen the deaths of 68,000 people, will dwarf the emissions caused by the conflict.

According to U.N. estimations, Israel's intensive bombardment destroyed over 90% of Gaza's housing, and has turned it into a wasteland. 60 million tons worth of debris were created.

Concrete and steel are used in huge quantities to rebuild homes and infrastructure. These materials have a high carbon footprint.

Neimark said that the loss of farmland and orchards, as well as shrubland in an area already susceptible to climate change effects, has increased the risk of desertification.

The two wars have also increased global emissions far from the frontlines.

Commercial flights have been forced to reroute due to airspace closures, increasing fuel consumption. De Klerk stated that flights from London to Tokyo take nearly three hours more.

The Middle East unrest has also disrupted the international shipping in the Red Sea. This is due to the longer routes, and the increased speed of sailing.

MILITARY DATA HOLE

This new research about Gaza and Ukraine is a part of an overall push to increase transparency regarding global military emissions.

Even during peacetime, the carbon footprint of armies is large - from maintenance of bases to transporting troops and equipment. Military exercises, weapons production, and military exercises all add up.

According to the Conflict and Environment Observatory (a UK non-profit), about 5,5% of greenhouse gas emissions are attributed to militaries around the world.

However, countries are not required by international climate bodies to report their military emission.

Experts warn that the lack of data could lead us to underestimate the amount of emissions needed to keep the temperature rise to 1.5 degrees Celsius.

Many countries are increasing their defence spending to respond to multiple crises. This is causing concern that this will increase emissions from military equipment and divert funds away from climate change efforts.

Climate scientists say that militaries should be required to report their emissions.

Neimark stated that "we can't begin making meaningful cuts until we have adequate baselines."
