On Top of All of Israel's Other Bombs in Gaza, Study Reveals a War-Driven Carbon Bomb

"What we are facing is severely impacting all life in Gaza, and also threatening human rights in the region, and even globally, due to the aggravation of climate change," said one United Nations special rapporteur.

A group of researchers has released an updated analysis detailing the devastating impact that Israel's war on Gaza has had in terms of greenhouse gas emissions—in addition to loss of human life.

The study, first reported on by The Guardian and posted to SSRN on Friday, found that the projected planet-warming carbon emissions of "direct war activities" over 15 months of Israel’s military assault on Gaza were greater than the individual annual emissions of 36 countries and territories.

According to local health officials in Gaza, over 54,000 people have been killed in the enclave following October 7, 2023, when a deadly Hamas attack on Israel spurred a devastating military response.

"For over 600 days, Israel has been saying it's targeting Hamas, but it is civilians who have been corralled, bombed, and killed en masse every day," said Bushra Khalidi, policy lead in the Occupied Palestinian Territory for the anti-poverty group Oxfam, on Wednesday.

According to the study, 15-months of war, a period from October 2023 to January 2025, resulted in an estimated 1.89 million tonnes of carbon dioxide equivalent emissions. According to The Guardian's write up of the study, 99% of that 1.89 million tonnes of carbon dioxide equivalent was generated by Israel's ground invasion and aerial attacks on Gaza.

In January 2025, a cease-fire went into effect, but Israel ended the cease-fire in mid-March.

The estimated tonnes of carbon dioxide equivalent increases to 32.2 million tonnes when the study accounts for "pre-conflict and post-conflict related construction activities."

The pre-conflict emissions include the construction of security-related concrete infrastructure in both Israel and Gaza over the past 16 years, including Hamas' network of tunnels and Israel's "iron wall." Post-conflict relates to the future reconstruction needs of Gaza following extensive Israeli attacks.

"This updated research evidences the urgency to stop the escalating atrocities, and make sure that Israel and all states comply with international law, including the decisions from the [International Criminal Court] and the [International Court of Justice]," Astrid Puentes Riaño, U.N. special rapporteur on the human right to a clean, healthy, and sustainable environment, told The Guardian.

"Whether or not states agree on calling it a genocide, what we are facing is severely impacting all life in Gaza, and also threatening human rights in the region, and even globally, due to the aggravation of climate change," she added.

The study, which according to The Guardian is under peer review by the journal One Earth, follows a study released last year authored by some of the same researchers who tackled this same question of the climate costs of the war on Gaza.

"These calculations point to the urgent need for increased visibility and mandatory reporting of military emissions for both war and peacetime through the U.N. Framework Convention on Climate Change," the more recent study states, referencing a treaty ratified by nearly 200 countries in the 1990s to combat "dangerous" human interference with climate systems.
