The minute
- Brazil’s gross greenhouse gas emissions fell 6% in 2025 to 2.06 billion tonnes of CO2 equivalent, the lowest level in eight years, according to Seeg, the emissions estimate system run by Observatório do Clima.
- Seeg reports net emissions of 1.41 billion tonnes after 650 million tonnes of removals, and a 26% cumulative cut in gross emissions across three years of decline (-7.5% in 2023, -12.7% in 2024, -6% in 2025).
- Seeg attributes 39% of gross emissions to land-use change, 30% to agriculture, 21% to energy, 5% to waste and 5% to industrial processes. Outside land use, sectors were stable or higher: waste +3.6%, energy +1.2%, electricity generation +6%.
Why it matters: Three falling years in a row look like a trend. Seeg’s breakdown says otherwise: the whole decline rests on one source, slower deforestation. The sectors where most Brazilian companies actually operate (energy, transport, waste, industry) did not follow, and those are the ones corporate inventories and any future cap on emissions will measure directly.
One lever moved, the rest did not
Capital Reset reported the Seeg numbers the day they were presented, with the 6% drop as the headline. The headline is the least interesting part. Land-use change accounts for 39% of gross emissions, so the other 61% comes from sectors that Seeg shows as stable or rising. Had deforestation simply held flat in 2025, the national total would not have fallen. Nothing else was pulling it down.
The removals line leans on the same thing. Seeg’s 650 million tonnes of removals come from secondary vegetation growth and from protected areas, indigenous lands and conservation units. So both the emissions cut and the removals sit in the forest and land-use sector, and the net figure of 1.41 billion tonnes moves with a single policy area.
Seeg coordinator David Tsai, of Iema, described the last three years as the reversal of more than a decade of rising emissions. The source also notes that deforestation rose sharply between 2019 and 2022. That is the part worth sitting with: a reversal that depends on enforcement can be undone by the next change in enforcement.
What nobody can say yet is whether energy, waste and agriculture will start to bend. Seeg ties the 6% rise in electricity-sector emissions to gas-fired thermal plants being dispatched, and the waste increase to population growth, landfills, dumps and effluent treatment. None of that is a one-off. The source does not say whether 2026 repeats the pattern, so any forecast built on it would be guesswork.
Which Brazilian rules sit closest to these numbers
Seeg is a national estimate produced by a network of civil-society organizations. It is not a compliance instrument, and it does not assign emissions to companies. The Brazilian mechanisms nearest to it work at a different level. The Brazilian GHG Protocol Program lets companies publish voluntary inventories with a standard method, and the regulated carbon market created by federal law in 2024 (the SBCE) is meant to set obligations per installation and per company. This article does not verify the current state of its implementing rules, so companies should check that directly.
One thing is clear from the law as written: primary agricultural production, the second largest source in Seeg’s data at 30%, was left outside the cap’s obligations. The sector with the second largest footprint is not the one the market goes after first.

A comparison figure is missing here. The material has no company-level or sector-level benchmark for Brazilian firms, and Seeg’s national totals cannot stand in for one. A company that sets its own inventory against the 2.06 billion tonne total learns very little. Sector data from the same Seeg series, or inventories in the voluntary registry, would be the right yardstick. Neither is in the source.
Who gains and who loses
The 2025 data helps exporters and buyers who must show their supply chains are not tied to new clearing. Seeg records the decline in all biomes and states, with the largest drops in the Amazon and the Cerrado. Landholders whose operations depend on converting native vegetation lose room to expand, and Seeg identifies conversion for agriculture and urbanization as the core of the land-use category.
On the other side, gas-fired generators and the buyers of their power carry the electricity result. Municipal waste operators and landfill managers face the sector with the fastest proportional growth. Fleet operators and fuel distributors are exposed to the transport result, where Seeg points to higher diesel and gasoline consumption.
What it means for Brazilian companies
Take a company that reports Scope 2 emissions with the location-based method. Its input is the grid average factor. If thermal dispatch pushes up the factor published by the federal government, the same electricity use produces a higher reported number, even though the company changed nothing. Finance and sustainability teams should see this coming and explain it in their reports, instead of letting it read as operational backsliding.
Companies with large land-based supply chains can use the lower deforestation figures to open conversations with suppliers. The national drop, though, proves nothing about a specific farm or origin. Plot-level traceability is still the evidence buyers ask for.
The next national cuts have to come from waste, transport and energy, because Seeg shows no reduction in any of them. Developers of landfill gas, efficiency and fuel-switching projects work in exactly those sectors. Whether a regulated market makes such cuts pay depends on rules not yet applied, and that is the open question behind this year’s headline number.
