While the humanitarian tragedy of the Israel-Gaza war is widely documented, a groundbreaking study published in the journal One Earth (March 2026) reveals a staggering environmental toll that often remains “invisible.” Researchers have found that the conflict has generated approximately 33.2 million metric tons of carbon dioxide equivalent (CO2e), a figure comparable to the annual emissions of 7.6 million petrol-powered cars. 1. Active warfare: more than just rockets The study, led by Dr. Benjamin Neimark from Queen Mary University of London, breaks the emissions down into three main phases. The first is active military operations, which accounted for over 1.3 million tonnes of CO2e. This includes: 2. Defensive infrastructure Long before the current escalation, “pre-war” activities had already baked a massive carbon cost into the region. The construction of Hamas’s extensive underground tunnel network and Israel’s technologically advanced “Iron Wall” (a 65km barrier equipped with sensors and cameras) generated roughly 557,000 tonnes of CO2e. These massive engineering projects required vast amounts of concrete and steel two of the world’s most carbon-heavy materials. 3. The future toll: Reconstruction The most alarming finding is that the largest share of emissions over 90% is yet to come. The study estimates that rebuilding Gaza will produce nearly 30 million tonnes of CO2e. Reconstruction involves: Why this matters for the planet Currently, international climate frameworks (like the UNFCCC) do not require countries to report military emissions. This means the environmental impact of war is often a “blind spot” in global climate accounting. The researchers argue that by quantifying these emissions, they are making the “invisible visible.” The study calls for greater transparency and a global requirement for militaries to report their carbon footprints. As the world races to meet “Net Zero” targets, the environmental cost of conflict is a sobering reminder that war and climate change are deeply interconnected crises. Summary of the Impact
