Global fossil fuel emissions drop in 2026 due to Iran war and renewables

Oil prices and solar power drive decline

This year, global carbon dioxide emissions from fossil fuel combustion are expected to fall by 0.4 percent. This drop marks the first annual decrease since 2020 when the pandemic paralysed global trade. The US-led war in Iran and the closure of the Strait of Hormuz caused soaring crude prices. High oil costs led to reduced consumption which lowered overall emissions from burning oil, gas and coal. Simultaneously, solar panels, wind farms and electric vehicles contributed significantly to meeting rising energy demand.

Regional variations in carbon output

Oil-related emissions are projected to fall 1.9 percent while natural gas emissions decrease by 0.3 percent. Coal emissions are expected to rise slightly by 0.6 percent despite the overall decline. Major economies show different trends with EU emissions falling 1.5 percent and US figures dropping 1.3 percent. India is an exception as its emissions are expected to increase by 4.4 percent this year. Overall fossil carbon dioxide emissions are projected to reach 38.2 billion tonnes in 2026.

Scientists warn of short term drop

Pierre Friedlingstein from the University of Exeter stated that geopolitical shocks do not offer a sustainable climate solution. He emphasized that rapid deployment of clean energy technologies remains the long-term answer for reducing emissions. Corinne Le Quere from the University of East Anglia noted that emissions often rebound when economic shocks end. She warned that a drop driven by conflict is likely temporary once oil tensions disappear. Land-use emissions may also rise due to peat fires linked to strong El Nino conditions.
