What happened
Scientists reported that global carbon pollution decreased slightly in 2026, reaching 42.2 billion tons of heat-trapping carbon dioxide. The study concluded that this reduction was largely driven by oil shocks resulting from the war in Iran and the effective closure of the Strait of Hormuz, rather than global climate action. Oil emissions dropped nearly 2%, while coal emissions increased 0.6% and natural gas fell 0.3%.
Why it matters
The war in Iran has effectively closed the Strait of Hormuz, a vital shipping artery for petroleum products. This situation has pushed up global prices for gasoline and oil. The estimates were presented by scientists from the CICERO Center for International Climate Research during the COP31 summit in Antalya, Turkey.
COP31 is currently being held in Antalya, Turkey.
Who's involved
- Glen PetersScientist who presented the climate data findings.
- CICERO Center for International Climate ResearchResearch organization that published the global carbon estimates.
- AntalyaCity in Turkey where the climate data was presented.

- HormuzVital shipping artery that was effectively closed by the conflict.
Who could feel it
Possible knock-on effectsThese are possibilities Brind reasoned out, not predictions, and not advice. Most are not stated in any report.
- Pegasus AirlinesSpeculative
Oil shocks from the Iran war could increase operational costs for Pegasus Airlines.
- HormuzSpeculative
The closure of the Strait of Hormuz might affect global supply chains.
