Global fossil CO₂ emissions projected to dip as total rises

Global fossil-fuel carbon dioxide emissions are projected to fall 0.4% in 2026 to 38.2 billion tonnes, the Global Carbon Project said November 10.

The projected decline would be the first since 2020, when the COVID-19 pandemic disrupted energy use, Canary Media’s Dan McCarthy reported. This year’s estimate is a forecast for fossil-fuel CO₂ across the full year.

The picture changes when land-use emissions are included. The Global Carbon Project projects total CO₂ emissions of 43.3 billion tonnes in 2026, up from 42.8 billion tonnes in 2025. It expects emissions from land-use change, including deforestation, to rise to 5.1 billion tonnes this year.

The researchers attribute the projected fossil decline partly to expanding solar and wind power and to an energy shock linked to the Iran conflict. Oil-related CO₂ emissions are projected to fall 1.9% in 2026, the project said.

A single year’s decrease would not by itself establish a lasting peak. Glen Peters, a research professor at the CICERO Center for International Climate Research, said in the project’s release that a sustained decline depends on structural change.
