The story. Tropical primary forest loss dropped 36% in 2025 from 2024's record highs, according to satellite data from the University of Maryland's GLAD laboratory published on Global Forest Watch. But researchers warn the decline largely reflects fewer fires rather than durable gains — the tropics still lost 4.3 million hectares, an area larger than Switzerland (Mongabay).

The bigger picture. Brazil drove much of the improvement: its tree cover loss fell from 5.4 million hectares in 2024 to 3.8 million in 2025 (GFW), and its forest-related carbon emissions dropped from 2.12 to 1.48 billion tonnes of CO2-equivalent (GFW). For scale, Brazil's 2025 forest emissions alone equal roughly 10% of global power-sector CO2 emissions (Ember). But not every country followed suit. Indonesia's primary forest loss ticked up from 1.3 million hectares in 2024 to 1.4 million in 2025 (GFW), with commodity-driven deforestation — forest permanently cleared for commercial crops like palm oil — accounting for 57% of cumulative loss (GFW). The Democratic Republic of the Congo held steady at 1.3 million hectares (GFW), where 99% of cumulative loss is tied to shifting agriculture (GFW). Meanwhile, Madagascar and Nicaragua are losing more than 2.5% of their remaining primary forests each year (Mongabay).

The tension. Current loss levels sit 70% above what's needed to meet the 2030 Glasgow Leaders' Declaration — a pledge by over 140 countries to halt and reverse forest loss (Mongabay). Brazil's enforcement gains show policy works, but one country's progress can't offset a system where fires, weak governance, and commodity demand keep chipping away at the rest.
