Data released by the National Institute for Space Research (INPE), which tracks forest cover by satellite, showed that an area of vegetation four times the size of Greater London had been destroyed between August 2024 and July 2025.

Claudio Almeida, a coordinator at INPE, said the loss of 5,796 square kilometers (2,238 square miles) of native vegetation represented "the fourth consecutive year of a reduction" in deforestation.

The Amazon rainforest, which spans nine countries, plays a key role in storing plant-harming carbon and is considered critical in the fight against climate change.

Brazil, which has pledged zero deforestation by 2030, has put forest protection as a top priority for the COP30 climate talks, which will take place in the Amazon city of Belem in November.
