Fossil fuel emissions are expected to fall in 2026. Why aren’t climate experts celebrating?
Experts warn that a drop in emissions partly driven by conflict and trade disruptions is not sustainable in the long term.
Global carbon emissions from fossil fuels are expected to decline in 2026, according to projections from the 2026 Global Carbon Budget. The anticipated reduction of 0.4 percent is attributed to the rapid expansion of renewable energy sources, amidst a backdrop of the Iran war energy crisis. Oil emissions are expected to decrease by 1.9 percent, while coal emissions may rise by 0.6 percent.
Professor Pierre Friedlingstein, director of the Global Carbon Budget Office, highlights that while the reduction in fossil CO2 emissions is encouraging, it is not a sustainable climate solution, as it is driven partly by geopolitical shocks. The total CO2 emissions for 2026 are projected to be 43.3 billion tonnes, up from 42.8 billion tonnes in 2025, due to a rise in emissions from land-use change, such as deforestation.
Experts emphasize the need for further acceleration of renewables and electrification to peak and sustain a decline in global emissions. The UN Climate Change Executive Secretary, Simon Stiell, acknowledged the importance of electric and clean energy solutions during the COP31 climate talks, stating that efficient electrification is vital in addressing pollution and rising household costs.
The EU is projected to see the steepest decline in fossil emissions among major emitters, at 1.5 percent, while the U.S. is expected to follow with a 1.3 percent reduction, primarily due to a drop in coal emissions. China, despite producing 32 percent of global fossil emissions, is set to see a 0.9 percent decline in 2026, largely due to a steep decline in oil emissions and strong growth in renewable electricity generation.
In contrast, India's emissions are projected to rise by 4.4 percent, exceeding its 3.5 percent average annual growth over the last decade.
While the clean tech sector, including solar, wind, and electric vehicles, is making strides in offsetting global energy demand, progress remains slow. Between now and the end of 2028, 64 to 79 percent of emissions from new demand are projected to be offset by new solar, wind power, and electric vehicles. However, carbon removal efforts, such as reforestation and afforestation, currently offset less than 30 minutes of annual fossil emissions.
