Conserving the world’s forests can generate multiple climate benefits by preventing the release of their large carbon stores into the atmosphere, safeguarding their ability to continue sequestering carbon, and, for tropical forests, maintaining the biophysical mechanisms that help to cool the planet. To help secure these benefits, the Glasgow Leaders’ Declaration has established the collective goal of halting forest loss—which includes reaching zero gross deforestation—by 2030.
The world permanently lost at least 5.8 million hectares (Mha) of forests in 2022, with some estimating that the loss was even higher at 6.6 Mha. Global deforestation increased slightly compared to 2021. Should current trends continue, the world will fail to halt permanent forest loss by 2030. The annual rate of gross deforestation instead must fall by nearly 1 Mha each year throughout the rest of this decade to deliver on the GLD’s goal.
Deforestation and the trajectory to the 2030 goal (with and without areas of tree cover loss cleared by fires)
Why do we provide two estimates of deforestation?
Deforestation is defined as the permanent conversion of natural forest cover to new, non-forest land uses. Different global data and methods can be used to approximate deforestation, though none perfectly captures trends in permanent forest loss.
Here, we provide two estimates resulting from two different methodologies. Both use a combination of datasets available on Global Forest Watch and estimate deforestation as the areas of tree cover loss where the dominant driver is the production of commodities (namely large-scale agriculture and pastures, and mining), urbanization, or the expansion of shifting agriculture in humid tropical primary forests.
However, the two methodologies treat the presence of fires differently. Tree cover loss from fire includes both natural and human-ignited fires where fire was the direct cause of loss (e.g., does not include burning of felled trees), and can be temporary in nature or lead to permanent land use change.
To illustrate this point, one methodology—described in the State of Climate Action 2023—excludes all tree cover loss due to fire that occurs within the areas described above, while the other methodology—described in the 2023 Forest Declaration Assessment—does not.
While neither of the resulting estimates can be considered perfectly accurate, each serves as an effort to present a realistic depiction of global deforestation trends.
Deforestation (including areas of tree cover loss cleared by fires)
When including areas of tree cover loss cleared by fires, the Forest Declaration Assessment finds that deforestation occurred across 6.6 Mha worldwide in 2022. This represents a 4% increase compared to 2021.
Deforestation (excluding areas of tree cover loss cleared by fires)
When excluding areas of tree cover loss cleared by fires, the State of Climate Action 2023 finds that 5.8 Mha of deforestation occurred globally in 2022—a 7% increase relative to 2021.
