Brazilian President Jair Bolsonaro recently pledged to end illegal deforestation this month while at the United Nations climate summit, The Associated Press reported. The National Institute for Space Research’s Prodes monitoring system released a report with the numbers before the summit started on Oct. 27.

The report references the months of Aug. 2020 to July 2021. This is the most forest lost in a year since 2006.

Early data for the 2021-2022 reference period signals further deterioration. The space agency’s monthly monitoring system, Deter, detected higher deforestation year-on-year during both September and October. Deter is less reliable than Prodes, but widely seen as a leading indicator.
