Heat-Trapping Carbon Pollution Drops, but Scientists Cite the Iran War Rather than Energy Progress
Researchers attributed the 0.4% drop in fossil fuel emissions to 42.2 billion tons to higher petroleum prices from Strait of Hormuz shipping disruptions.
- Global fossil-fuel CO2 emissions decreased 0.4% this year, according to scientists from the Global Carbon Project, a slight decline primarily driven by oil supply shocks stemming from the war in Iran.
- The war in Iran closed the Strait of Hormuz, a vital shipping artery for petroleum, causing oil emissions to drop nearly 2% while natural gas fell 0.3% and coal rose 0.6%.
- Despite the fossil-fuel drop, overall carbon emissions rose 1% due to deforestation and human-caused peat fires increasing faster than fossil fuel burning decreased, with total emissions reaching 42.2 billion tons.
- India saw fossil-fuel pollution surge 4.4% this year, while major polluters including China, the United States, Europe, and Japan showed about a 1% drop in emissions, according to the study.
- Experts debate whether this decline represents a permanent shift or a temporary response to oil shocks, particularly as global emissions continue at a rate of about 1,335 tons per second.

Fossil fuel emissions fall due to Iran war and renewables, finds research
Emissions from the burning of oil, gas and coal -- the main drivers of climate change -- rose by 0.9 percent per year on average in the past decade, hitting a record high in 2025, according to the Global Carbon Budget report.
Heat-trapping carbon pollution drops, but scientists cite the Iran war rather than energy progress – WTOP News
Global carbon pollution dropped this year ever so slightly, but it’s more because of oil shocks reverberating from the Iran war than anything the world has done to fight climate change, scientists said in a new study. In 2026, the world emitted 42.2 billion tons (38.2 billion metric tons) of heat-trapping carbon dioxide from the...

Heat-trapping carbon pollution drops, but scientists cite the Iran war rather than energy progress
Global carbon pollution dropped this year ever so slightly, but it's more because of oil shocks reverberating from the Iran war than anything the world has done to fight climate change, scientists said in a new study.
The conflict in Iran led to world oil consumption, contributing to a slight decline in fossil-based carbon dioxide emissions in 2026, according to a study published this Tuesday, November 10.
