Global Rainforest Loss Slows in 2025 After Record Year

AI Summary
A new study shows tropical primary rainforest loss fell to 4.3 million hectares in 2025, a 36 percent drop from the previous record year. The decline is linked to stronger policies in Brazil and Colombia, but climate‑driven fires remain a major risk.

The latest satellite‑based assessment reveals that the world’s tropical primary rainforests shed 4.3 million hectares in 2025 – a 36 percent reduction from the 2024 peak – yet the pace remains far above what is needed to meet the 2030 zero‑loss target.

Record‑Breaking Deforestation Followed by a Notable Decline in 2025

Researchers from World Resources Institute (WRI) and the University of Maryland highlighted that while 2024 set an all‑time high for forest clearance, 2025 showed a measurable pull‑back. The slowdown was not uniform; Brazil accounted for the bulk of the improvement, while the Democratic Republic of the Congo and Cameroon continued to experience high loss rates.

Numbers Behind the Slowdown: 4.3 Million Hectares Saved

  • 4.3 million hectares (10.6 million acres) lost in 2025, down from 6.7 million hectares in 2024.
  • Loss was 46 percent lower than in 2015.
  • Global tree‑cover loss fell 14 percent year‑on‑year.
  • Fires accounted for 42 percent of tropical forest loss.
  • Brazil’s non‑fire forest loss dropped 41 percent from 2024, its lowest on record.
  • Colombia’s loss fell 17 percent, the second‑lowest since 2016.

Policy Wins in Brazil and Colombia Signal Shifting Conservation Landscape

Brazil’s decline is attributed to stricter enforcement and the anti‑deforestation action plan relaunched by President Luiz Inácio Lula da Silva in 2023, which raised penalties for illegal clearing. Colombia benefitted from new governmental agreements limiting forest clearing. However, both nations face ongoing pressures from soy and cattle expansion, and local attempts to dilute environmental protections.

Future Outlook: Climate‑Driven Fires Threaten to Reverse Gains

Researchers warn that the return of a strong El Niño mid‑year could reignite heatwaves, droughts and wildfires, potentially erasing the 2025 gains. While human activity sparks most tropical fires, climate change is intensifying natural fire cycles, turning forests from carbon sinks into emission sources. As Rod Taylor of WRI cautioned, “We’re on a kind of knife’s edge.”
