**Global fossil-fuel carbon dioxide emissions may edge lower in 2026, but that does
not mean humanity’s overall carbon pollution is falling.** The [Global Carbon Project’s November 10 assessment](https://globalcarbonbudget.org/fossil-co2-emissions-decrease-in-2026/)
projects a 0.4% decline in fossil CO₂ emissions to 38.2 billion metric tonnes. Once
land-use changes such as deforestation are included, however, total human-caused
CO₂ emissions are forecast to _rise_ from 42.8 billion tonnes in 2025 to 43.3 billion
tonnes in 2026.

## Why the headline decline is not a climate turning point

The projected reduction is small and uncertain: the [research preprint](https://essd.copernicus.org/preprints/essd-2026-895/)
places its central fossil-emissions estimate at −0.40%, with an uncertainty range
from −1.5% to +0.6%. That range includes a possible increase. It would therefore
be premature to declare that global fossil emissions have definitively peaked.

Oil-related emissions are expected to drop about 1.9%, partly because energy-price
disruption associated with the Iran conflict reduced demand. Expanding solar and
wind generation and electric vehicles are also changing the energy mix. But a geopolitical
shock is not the same as a durable, policy-driven reduction in fossil-fuel use. 
Coal emissions are projected to increase around 0.6%, even as gas emissions edge
down.

## The land-use warning

Deforestation and other land-use changes explain the seemingly contradictory forecasts:
fossil CO₂ can decrease while total CO₂ increases. These are different accounting
categories, and confusing them would overstate climate progress. The 2026 estimate
for total emissions is 43.3 billion tonnes, compared with 42.8 billion tonnes in
2025.

## What to watch next

The critical test is whether emissions decline repeatedly as clean energy displaces
fossil fuels—not merely because a conflict temporarily suppresses consumption. The
project’s [2026 FAQ](https://globalcarbonbudget.org/gcb-2026/the-global-carbon-budget-faqs-2026/)
puts the remaining carbon budget for a 50% chance of limiting warming to 1.5°C at
about 150 billion tonnes, less than four years at today’s emissions rate. That is
a probabilistic scientific estimate, not a countdown to a single predetermined climate
event.
