Tropical forest loss declined significantly last year, falling
36% after reaching a record level in 2024. Still, the world lost
10.6 million acres of rainforest — an area roughly the size of
Denmark, or more than 11 soccer fields every minute.
New data from the University of Maryland, published through the
World Resources Institute’s Global Forest Watch, shows that the
loss of mature and largely undisturbed humid tropical forests
slowed down in 2025. But it was still 46% higher than a decade
earlier, and last year saw a relative lull in wildfires after an
exceptionally bad fire year in 2024. Blazes are increasing in
the tropics due to warmer temperatures and more severe droughts.
Outside the tropics, the climate signal was starker. Wildfires
burned 13 million acres in Canada, making 2025 the country’s
second-worst fire year on record. In France, fire-driven
tree-cover loss was the most severe on record, seven times
higher than in the previous year.
The analysis uses a broad definition of forest loss that
includes not just deforestation for agriculture but also timber
harvesting and natural disturbances to forests.
At the COP26 climate summit in 2021, more than 100 countries
pledged to halt and reverse forest loss by 2030. The world
remains far from that goal as agricultural expansion and fires
continue to destroy important biodiversity hotspots and carbon
sinks. Forest loss in 2025 was still about 70% too high for
countries to be on track for the deadline, according to the
World Resources Institute, or WRI.
“Achieving this goal in the coming years will not be easy as
forests become more vulnerable to climate change, and as
humanity’s demand for food, fuel and materials from forests and
the lands they stand on continues to grow,” said Elizabeth
Goldman, co-director of Global Forest Watch at WRI, during a
press briefing.
Agriculture — both large-scale commodity production and
subsistence farming — was the biggest driver of tree-cover loss
across the tropics in 2025. In countries Brazil and Bolivia,
cattle ranching and soy cultivation were major pressures, while
coca, oil palms and other crops drove losses in Peru, Laos and
elsewhere.
In much of the Congo Basin, forest clearing was tied more
closely to shifting cultivation patterns, demand for wood fuel
and poverty.
Fires increasingly interact with those pressures. They have
consumed twice as much tree cover in the past three years as
they did between 2003 and 2005, according to WRI. In the
tropics, most fires are sparked by human activity, but hotter
and drier conditions linked to climate change are making forests
more flammable and allowing wildfires to spread farther and
cause more damage.
Brazil, which encompasses two-thirds of the Amazon, the world’s
largest rainforest, recorded the largest absolute area of
primary forest loss. But it cut that loss by 42% from the
previous year. The report attributes the decline to stronger
environmental policy and enforcement under President Luiz Inácio
Lula da Silva.
The improvement stands in stark contrast to 2024, when Brazil’s
Amazon suffered its worst drought on record, fueling
unprecedented forest fires.
André Lima, Brazil’s secretary for deforestation control, said
in a phone interview that the country’s forest policy rests on
“two agendas that are intertwined” — curbing deforestation and
controlling fires. He said the government relaunched the federal
anti-deforestation plan in 2023 under Lula and is now beginning
to see results. Citing Brazil’s official data, Lima said Amazon
deforestation fell 50% in 2025 compared with 2022.
On fires, Lima argued that the spike in late 2024 should be seen
less as a policy breakdown than the result of exceptional
climate conditions: a strong El Niño, North Atlantic warming and
two consecutive years of drought that left the Amazon far more
flammable. He said the government has since stepped up its
response with $380 million for fire control, new prevention
rules and more support for state fire brigades and municipal
involvement.
“A good year is a good year, but you need good years forever if
you’re going to conserve the tropical rainforest,” said Matthew
Hansen, a remote sensing scientist at the University of Maryland
and director of its Global Land Analysis and Discovery (GLAD)
laboratory. “And we like the news from this year.”
