Deforestation in Brazil’s Amazon fell 41.8% in the year to July 2026, the largest decline since records began in 1988, satellite data shows. Brazil’s government also reported a record low in its Cerrado savanna region, where the rate fell 23.8%.

The figures come before a presidential run-off on 25 October between President Luiz Inácio Lula da Silva and Flavio Bolsonaro, son of former president Jair Bolsonaro. Polls suggest a close race, with the rainforest’s future a central issue.

Forest clearance surged under Jair Bolsonaro. Lula, who took office three years ago, has strengthened environmental monitoring and penalties for illegal logging and pledged to end Amazon deforestation by 2030. Flavio Bolsonaro is expected to continue his father’s policies if elected, though he has promised to tackle organised crime in the Amazon.

About 60% of the Amazon rainforest lies in Brazil. The forest absorbs carbon dioxide and is a crucial buffer against climate change.
