Iran War Unexpectedly Drove Down Carbon Emissions This Year
Confirmed
In Short: The Global Carbon Project reports a 0.4 percent decrease in fossil fuel emissions this year, largely driven by disruptions in the Strait of Hormuz.
The Global Carbon Project's 2026 edition of the global carbon budget reveals a slight decrease in fossil fuel emissions, down 0.4 percent from the previous year, according to the report.
Oil emissions, which have dropped by 2 percent, are the primary driver of this reduction, likely due to prolonged disruptions in the Strait of Hormuz caused by the ongoing Iran war.
While the report highlights a decline in carbon emissions, experts caution that this reduction is not sustainable and is largely due to geopolitical shocks rather than global efforts to combat climate change.
Pierre Friedlingstein, lead researcher and director of the Global Carbon Budget Office at the University of Exeter, emphasized that clean energy is not growing fast enough to ensure a durable drop in emissions.
The report projects that total carbon emissions will rise from 42.8 billion tonnes last year to 43.3 billion tonnes in 2026, underscoring the need for accelerated electrification efforts to achieve a lasting shift.
South Korea plans to invest up to $747 billion in renewable energy, electric vehicle uptake, and industry decarbonization by 2035, addressing energy security concerns and tightening global carbon regulations.
Experts agree that while the momentum towards cleaner energy is strong, more aggressive policies are needed to transition to net zero emissions.
The Global Carbon Project's research highlights the need for sustained and accelerated efforts to combat climate change, as the current reduction in emissions is not sufficient to ensure long-term sustainability.
What this adds
The slight decline in emissions is attributed to geopolitical shocks rather than global climate policies, raising concerns about the sustainability of this reduction.
The report does not specify the exact impact of the Iran war on emissions, but experts suggest that disruptions in the Strait of Hormuz have significantly affected oil emissions.
The Global Carbon Project's projections for 2026 indicate that further acceleration in clean energy deployment is necessary to achieve a sustained decline in emissions.
What's confirmed
- "While renewables and electric vehicles are increasingly offsetting growth in energy demand, further acceleration is needed if global emissions are to peak and enter a sustained decline." Total carbon emissions are set to rise from 42.8 billion tonnes last year to 43.3 billion tonnes in 2026.
- Research released by the Global Carbon Project projects emissions from the burning of fossil fuels to decrease by 0.4 per cent compared to 2025.
What's still developing
- "We've reached the tipping point, particularly on EVs."
- "I think the momentum is unstoppable," she said.
- Carbon Brief notes fossil CO2 projections have a range from -1.5% to +0.6% Glen Peters, a scientist at the CICERO Center for International Climate Research, said the study’s 2026 decline is “largely driven by the war in Iran” and the disruption of the Strait of Hormuz.
- This is highlighted in the prestigious annual study conducted by Global Carbon Project and published this Tuesday in the journal Nature Climate Change, coinciding with the Climate Summit in Antalya (COP31), Turkey.
- If the world is to reduce its carbon emissions and tackle climate change, it needs to move away from fossil fuels to low-carbon power.
