The Global Carbon Project said in its annual budget, released November 10, that global CO₂ emissions from fossil fuels are forecast to fall 0.4% in 2026, but rising emissions from land-use change could push total human-caused CO₂ to a record 43.3 billion tonnes.
The report forecasts 38.2 billion tonnes of emissions from fossil fuels and cement. Its forecast range is from a 1.5% fall to a 0.6% rise, so a small increase remains possible. Oil emissions are expected to fall 1.9%, reflecting both greater use of clean energy and an energy shock linked to the Iran conflict.
Coal emissions are projected to rise slightly. Solar power, wind power and electric vehicles are meeting about two-thirds of the growth in global energy demand. Researchers say this progress is still not enough to ensure that fossil-fuel emissions keep falling over time.
Emissions from land-use change, including those linked to deforestation, are expected to rise. The report cites peat fires and damage to forests in Southeast Asia among the factors. Together, these emissions are projected to exceed the 42.8 billion tonnes recorded in 2025.
The report estimates that the remaining amount of carbon that can be emitted while limiting warming to 1.5°C is about 150 billion tonnes, less than four years of emissions at current rates.
