Global fossil fuel emissions set to dip 0.4% in 2026, largely due to Iran war
Scientists project global fossil fuel emissions will fall 0.4% in 2026, to about 38.2 billion tonnes of carbon dioxide.
The Global Carbon Project’s estimate covers emissions from burning coal, oil and gas worldwide.
The drop is linked partly to the Iran war, which has disrupted shipments through the Strait of Hormuz and pushed up oil and gas prices.
Oil emissions are expected to fall 1.9%, while coal emissions rise 0.6% and gas emissions edge down 0.3%.
Clean energy is growing but has not yet made fossil fuel emissions fall steadily; researchers say renewables and electric vehicles are helping meet rising energy demand.
Emissions from land-use change, including deforestation, are expected to rise, so total carbon dioxide emissions are projected to increase to 43.3 billion tonnes.
Researchers say lasting cuts depend on faster clean energy growth, and the 2026 decline may not continue once the energy shock eases.
Global fossil fuel carbon dioxide emissions are projected to fall by 0.4 percent in 2026 to about 38.2 billion tonnes.
Researchers say the decline is partly linked to an energy shock caused by the conflict involving Iran, which has raised fuel prices.
Oil emissions are forecast to fall by 1.9 percent, while coal emissions are expected to rise by 0.6 percent.
Renewable energy and electric vehicles are helping limit emissions growth, but researchers say the energy transition needs to accelerate.
Total carbon dioxide emissions, including those from land-use change, are projected to rise to 43.3 billion tonnes in 2026.
- Who
- The Global Carbon Project and more than 130 scientists. Researchers including lead author Pierre Friedlingstein contributed to the report.
- What
- Global emissions from fossil fuels are projected to decline by 0.4 percent in 2026. The decline may be temporary and partly driven by the energy shock linked to the Iran conflict.
- When
- In 2026, according to projections published on November 9 in Nature Climate Change.
- Where
- Worldwide.
- Why
- The projected decline is partly linked to higher fuel prices and disruption to energy markets from the Iran conflict. Renewable energy and electric vehicles are also helping to limit emissions growth.
This story does not have two clearly opposing sides.
Global fossil fuel emissions grew by an average of 0.8 percent each year.
Researchers reported their projections in Nature Climate Change.
Fossil fuel emissions are projected to fall by 0.4 percent, while total emissions are expected to rise to 43.3 billion tonnes.
If electric vehicle sales and wind and solar capacity keep growing at their 2026 rates, those technologies are projected to counteract about 63 percent of emissions growth.

Fossil fuel emissions are down in 2026. Green energy isn’t the reason
What people are saying
A decline in fossil CO2 emissions is encouraging, but a reduction driven partly by geopolitical shocks is not a sustainable climate solution.
So the energy transition that’s happening … it’s not quite big enough to get emissions heading downward yet.
Clean technologies are making a real difference in reducing global emissions.
