The loss of tropical rainforests slowed last year, new satellite data suggests, largely due to Brazil's efforts to curb deforestation in the Amazon.
Researchers estimate that nearly 43,000 sq km (17,000 sq miles) of old-growth tropical forests were lost globally in 2025 – about the size of Denmark.
While it is about a third lower than record losses in 2024, scientists warn that tropical forests - among the Earth's most important ecosystems - are still disappearing much faster than a decade ago.
There is also concern that a two-pronged attack from climate change and the arrival of the warming El Niño weather pattern later this year could increase the likelihood and severity of forest fires.
The latest figures show that the loss of tropical forests fell by 36% in 2025, according to analysis from the World Resources Institute and the University of Maryland.
