Brazil's State Push Cuts Forest Clearing, Study Says

Brazil’s National Institute for Space Research reported that Amazon deforestation fell to 3,335 square kilometres between August 2025 and July 2026. The federal government credited monitoring, inspections, land-tenure measures and farm incentives for the decline. An economist at the Getulio Vargas Foundation estimates that lower deforestation from 2023 to 2026 avoided 1.49 billion tonnes of greenhouse gas emissions, with a modelled value of R$1.16 trillion, or US$216 billion at 2024 prices.

That figure puts a price on forest protection. It isn’t money Brazil has received. Bráulio Borges of FGV’s Brazilian Institute of Economics, known as Ibre, published the estimate on Monday, October 19, 2026. His calculation assumes deforestation would have stayed at the 2019-to-2022 average without the policy change from 2023. Emissions for 2025 and 2026 rely on models using official data through 2024.

The state’s enforcement apparatus

INPE said Amazon deforestation fell 41.8% from 5,731 square kilometres a year earlier. The institute said the estimate, based on priority images, marked the lowest level in its series, which began in 1988. The consolidated rate is due in the first half of 2027. In the Cerrado, clearing fell 23.8% to 5,516.69 square kilometres, the lowest since that series began in 2001.

The federal government credited satellite monitoring, inspections, land-tenure measures and farm incentives under two action plans it restored in 2023. From 2023 to 2026, the environment agency Ibama carried out 76,095 inspections and issued 25,101 fines for offenses against flora worth R$11.8 billion, or US$2.4 billion, according to INPE’s release. The agency also embargoed 18,630 square kilometres. The sources didn’t establish how much of the fines had been collected.

Losses and enforcement varied across the map. Pará lost 1,130 square kilometres of Amazon forest, Mato Grosso 849 and Amazonas 525. The four states in the Matopiba frontier accounted for 74.3% of Cerrado clearing. Maranhão lost 1,718.59 square kilometres and Tocantins 1,263.06.

What the price tag counts—and misses

Borges said Amazon clearing was 71% below the 11,594 square kilometres recorded in 2022. Combined clearing in the Amazon and Cerrado fell from 22,300 square kilometres in 2022 to 8,900 in 2026, a decline of about 60%. Compared with the earlier average of about 19,700 square kilometres a year, clearing from 2023 to 2026 left about 22,300 square kilometres uncleared—an area slightly larger than Sergipe.

Borges’s central estimate uses a social cost of carbon of US$145 per tonne, the average of studies from the previous 10 years in a database maintained by economist Richard Tol of the University of Sussex. The Environment Ministry’s lower estimate was 1.1 billion tonnes. Borges treated that as a floor, valuing it at about US$160 billion with the same carbon price. A median drawn from recent studies yields US$115 billion, or R$621 billion. A 2026 paper by Bilal and Känzig in the Quarterly Journal of Economics would produce R$9.8 trillion, about US$1.8 trillion. Borges called that estimate controversial because it extrapolates from data for 1960 to 2019.

For Brazil’s domestic economy, Borges estimated a gain of US$12.4 billion, or R$67 billion, using a local carbon cost of about US$8.3 per tonne. Using a national value of US$24 per tonne from a 2018 paper in Nature Climate Change raises the estimate to US$36 billion, or R$192 billion. He said much of the benefit comes from avoided damage, including fewer crop losses and less heat stress on workers—costs no official statistic records. His estimate excludes the forest’s effect on regional rainfall, which a study he cited valued at about US$20 billion a year.

Funding isn’t the same as the value created

The Amazon Fund, managed by development bank BNDES, had approved 160 projects and committed R$7.8 billion, or US$1.6 billion, in October 2026. On October 16, it announced R$147.6 million, or US$29 million, for an INPE system that uses artificial intelligence to combine yearly Prodes counts with near-real-time Deter alerts. Borges said the global benefit exceeds what Brazil receives from the Amazon Fund, carbon credit markets and the Tropical Forest Forever Facility, launched at the COP30 climate summit in Belém in 2025. He called those payments “a very small fraction” of the estimated gains.

The US$216 billion is a modelled estimate, not a bill or payment due to Brazil. FGV said the opinions in the Ibre post were Borges’s alone, not an institutional position. The sources haven’t established whether the decline will continue. The forests’ estimated value is immense; the money actually committed is a separate, much smaller figure.
