The U.S. war with Iran has raised fossil fuel prices so much that the resulting drop in oil demand has put the world on track to see a rare dip in carbon emissions from these sources in 2026.
Between 2019 and 2025, carbon dioxide emissions from fossil fuels grew by about 0.8 percent annually, according to a new study published in Nature Climate Change. But 2026 is set to buck that trend: high oil prices, as well as the continued rise of green technology—solar power, wind and electric cars—will cause a “short-term” 0.4 percent drop, according to the study.
“The high petrol prices following the war in Iran are reducing oil use and keeping emissions low,” says the study’s lead author Corinne Le Quéré, a professor of climate change science at the University of East Anglia in England. “But that’s not the whole story: The expansion of renewable energy has progressed a lot in recent years, led by China. And [along with electric vehicles], this is offsetting two thirds of the growing demand for energy.”
With all sources of carbon considered, including deforestation, total global CO2 emissions are set to continue increasing.



There’s still a choice. They can decide whether to drive a 15 year old pickup or a 15 year old Toyota. They have choices in how often and how far they drive. They have choices in shared transportation. Some of those choices are immediate and some build up until a bigger decision.
I’m old enough to remember car pools over commuting alone, shared shopping trips, people managing even when not everyone had a car. I remember a before time where not every adult had a car and not every car was a full sized pickup
