Global Carbon Project: fossil CO2 emissions to fall 0.4% in 2026
The Global Carbon Project's 2026 Global Carbon Budget projects fossil fuel CO2 emissions will fall 0.4% to 38.2 billion tonnes, attributing the dip partly to solar and wind expansion and partly to an oil demand drop tied to the Iran conflict. Including land-use emissions such as deforestation, total CO2 output is projected to rise to 43.3 billion tonnes, up from 42.8 billion tonnes in 2025, with the remaining 1.5°C carbon budget now at about 150 billion tonnes.
