Phys.org: Global CO2 emissions fell 0.4% in 2026 due to Iran war oil shock
Briefing by News4U · First published
Phys.org reports that global fossil-fuel carbon dioxide emissions fell 0.4% to 42.2 billion tons in 2026, driven by the Iran war closing the Strait of Hormuz rather than clean-energy gains. Oil emissions dropped nearly 2% and natural gas 0.3%, while coal rose 0.6%. Overall CO2 emissions rose 1% because land-use changes outpaced the fossil-fuel decline. China, the United States, Europe and Japan each saw about a 1% drop, whereas India’s emissions rose 4.4%. [1]
