Global Rainforest Loss Slows in 2025 Thanks to Brazil’s Bold Policies

In 2025, the world’s tropical primary rainforest loss dropped by 36% compared to the previous year, totaling 4.3 million hectares, according to a new study by the World Resources Institute and the University of Maryland. This slowdown follows a record high in 2024 and is largely credited to decisive government actions, especially in Brazil.

Despite this encouraging decline, the pace of forest destruction remains alarmingly high—46% above levels from a decade ago—and climate change-driven fires pose a growing threat that could reverse recent gains. The findings highlight the urgent need for sustained environmental policies to protect these vital ecosystems.

Brazil’s Environmental Policies Drive Significant Decline

Brazil, home to the world’s largest rainforest, saw a 41% reduction in forest loss excluding fires—the lowest rate ever recorded. This improvement is linked to stronger enforcement and environmental policies implemented since President Luiz Inacio Lula da Silva took office in 2023, including a relaunch of the anti-deforestation action plan and increased penalties for environmental crimes.

However, threats persist from agricultural expansion for soy and cattle ranching, as well as local efforts to weaken environmental protections.

Progress Beyond Brazil and Persistent Global Challenges

Other countries like Colombia also reported progress, with a 17% drop in forest loss, marking the second lowest since 2016. Yet, tropical forest loss remains high in regions such as the Democratic Republic of the Congo and Cameroon.

• Global tree cover loss fell by 14% in 2025.
• Fires accounted for 42% of tropical forest destruction worldwide.
• Canada experienced its second-worst wildfire year, burning 5.3 million hectares.

“A drop of this scale in a single year is encouraging – it shows what decisive government action can achieve,” said Elizabeth Goldman, co-director of WRI’s Global Forest Watch platform.

“We’re on a kind of knife’s edge,” added Rod Taylor, WRI’s global director for forests, highlighting how fires and droughts on a warming planet are turning forests from carbon sinks into sources of greenhouse gas emissions.

Climate Change and the Threat of Fires: A Dangerous New Normal

The study warns that climate change-induced fires have become a persistent threat, undermining efforts to curb deforestation. The anticipated return of the El Niño weather pattern in mid-2026 could exacerbate heatwaves, droughts, and wildfires, further endangering tropical forests.

While human activity causes most tropical fires, climate change intensifies natural fire cycles in northern and temperate regions, increasing the risk of large-scale forest loss.

Looking Ahead: Urgency for Continued Action

Despite the positive signs from 2025, global forest loss remains 70% above the level needed to meet the 2030 goal of halting and reversing deforestation. The study underscores the critical importance of maintaining and strengthening environmental policies worldwide to protect forests, combat climate change, and preserve biodiversity.

Sustained government commitment, combined with global cooperation, will be essential to prevent further degradation and to secure the future of the planet’s vital tropical rainforests.
