Brazil Amazon deforestation falls to near four-decade low

· Climate · Brazil

Deforestation in the Brazilian Amazon fell by nearly 42% to a record low between August 2025 and July 2026, the lowest since records began in 1988. The decline is a success for President Lula ahead of a presidential run-off, but whether the globally important gain is maintained or reversed is seen as on a knife edge. The data underscores the stakes of Brazil's election for climate policy and the world's largest rainforest.

Why it matters：The Amazon's fate matters globally for climate stability, and Brazil's election could determine whether the deforestation decline continues.
