Oil shock from Iran war led to drop in carbon pollution, scientists say
Summary
Global fossil-fuel carbon dioxide emissions are projected to fall 0.4% in 2026 to 42.2 billion tons, largely because the Iran war disrupted oil shipments through the Strait of Hormuz and drove up energy prices. Scientists said the decline may not last; total global carbon dioxide emissions, including those from land-use changes, are expected to rise 1%.Key Facts
- Oil emissions fell nearly 2% in 2026, while natural gas emissions fell 0.3% and coal emissions rose 0.6%.
- The Global Carbon Project’s international team of more than 140 scientists calculated the annual emissions estimate using data from around the world.
- The Strait of Hormuz is a vital route for petroleum shipments, and the war in Iran has effectively closed it, according to the article.
- The 2026 fossil-fuel emissions decline is the third global drop this century; the other declines occurred during the 2009 recession and the 2020 COVID-19 pandemic.
- Land-use changes, including deforestation and human-caused peat fires, contributed to a projected 1% rise in total global carbon dioxide emissions.
- The article estimates that fossil-fuel emissions in 2026 released about 1,335 tons of carbon dioxide per second.
- Researchers and outside experts differed on whether the drop signals a lasting peak in emissions, citing both growing electric vehicle use and the potential for increased oil production elsewhere.
