Global carbon emissions fall 0.4% in 2026 amid Iran war shocks, not clean-energy gains
In 2026, global fossil-fuel CO2 emissions fell to 42.2 billion tonnes, but scientists linked the drop mainly to the Iran war and Strait of Hormuz disruption.
Key highlights
Direct fact
In November 2026, the Global Carbon Project said world fossil-fuel carbon dioxide emissions fell to 42.2 billion tonnes, a 0.4% decline from 2025, and presented the estimate at the UN climate talks in Antalya, Turkiye.
Key specifics
- 2026 emissions were 42.2 billion tonnes of CO2, or about 1,335 tonnes every second.
- Oil emissions fell nearly 2%, natural gas fell 0.3%, while coal rose 0.6%.
- The study said the fall was linked mainly to the Iran war and disruption in the Strait of Hormuz.
- This was the third global carbon pollution drop in the 21st century, after 2009 and 2020.
- The estimate was published by the Global Carbon Project in Earth System Science Data Discussions.
Exam lens
Question type: Environment current affairs and data-based MCQ, key facts: 42.2 billion tonnes, 0.4% fall, Strait of Hormuz, 2009 and 2020 comparison. TNPSC one-liner: global CO2 emissions dipped in 2026, but the reason was war-linked oil shocks, not a structural energy transition.
