The amount of land burned in the world's largest rainforest was the smallest since MapBiomas records began in 1985.

The area burned in Brazil's Amazon in 2025 was far smaller in size than the previous year, according to the deforestation monitoring group MapBiomas. A MapBiomas report states that 3.1 million hectares of Brazil's Amazon were burned last year, compared with a record-breaking 15.8 million hectares in 2024. The amount of land burned in the world's largest rainforest last year covered the smallest area since MapBiomas records began in 1985. Protecting the Amazon was one of the pledges President Luiz Inácio Lula da Silva made when he was running for office four years ago. These latest figures will be seen as a boost to his campaign for re-election in October. In 2024, the Amazon rainforest experienced its worst forest fires in over two decades, which the Copernicus Climate Change Service put down to "climate extremes and human activity". "The 2025 figures are significant and show that it is possible to reduce the burned area in the country," Vera Arruda, a researcher at the Amazon Environmental Research Institute (IPAM) and co-ordinator at MapBiomas, told the BBC. "The 31% drop compared to the historical average - driven primarily by the lowest number of fires recorded in the Amazon in 41 years - is positive news, but it does not yet allow us to conclude that this is an established trend or to scale back prevention efforts," Arruda added. The MapBiomas report shows a dramatic drop in area burned not just in the Amazon, but across the whole of Brazil in 2025.
