What We Know About Flávio Bolsonaro's Lead in Brazil's Election

Flávio Bolsonaro took 47% of the vote in the first round of Brazil's presidential election, putting him ahead of incumbent Luiz Inácio Lula da Silva, who won 44.2%, according to the Guardian. The two face each other in a runoff on Oct. 25 that will determine the direction of Amazon rainforest policy for at least the next four years.

What were the first-round results?

Bolsonaro, the son of jailed former president Jair Bolsonaro, finished ahead of Lula by roughly three percentage points in preliminary results reported by the Guardian. The margin was close enough to leave the runoff outcome unsettled, but strong enough to put the far-right candidate in what the Guardian describes as "pole position" heading into the Oct. 25 vote.

Why does this matter for the Amazon?

Lula's current administration has cut Amazon deforestation by almost 50%, according to the Guardian. That reduction has not translated into electoral support for Lula or for candidates who campaigned on forest protection, a gap the Guardian says has prompted an "inquest" among climate campaigners into why curbing deforestation did not move voters.

The contrast with the elder Bolsonaro's record is sharp. During Jair Bolsonaro's four years in power, Amazon deforestation rose 59.5%, the Guardian reports, a figure the outlet says is roughly equivalent to a significant loss of forest cover. Flávio Bolsonaro is described in the Guardian's reporting as having "shown he is as willing as his father" to curb nature protections and allow Indigenous territories to be exploited, though the article does not cite specific legislation or votes by Flávio Bolsonaro himself on those points.

How did pro-forest candidates fare down-ballot?

The same election that produced Bolsonaro's first-round lead was difficult for politicians associated with forest and Indigenous-rights policy. Former environment minister Marina Silva lost her bid for a Senate seat, the Guardian reports. Joenia Wapichana, a former head of Brazil's Indigenous affairs agency, Funai, failed to win a seat in Congress. Of 57 Indigenous candidates who ran, only two won, according to the Guardian's count.

Those results suggest that Lula's deforestation record did not generate a broader coalition of support for nature-focused candidates elsewhere on the ballot, even as it registered internationally as a policy success.

What is the timeline from the first round to the runoff?

• Jair Bolsonaro's presidency (2019–2022): Amazon deforestation rose 59.5%, per the Guardian's reporting.
• Lula's current term: Deforestation falls by almost 50%, according to the same reporting.
• This week (reported Oct. 7, 2026): First-round results show Flávio Bolsonaro with 47% of the vote to Lula's 44.2%, per the Guardian.
• Same election day: Marina Silva loses her Senate race; Joenia Wapichana fails to win a Congress seat; only two of 57 Indigenous candidates win, the Guardian reports.
• Oct. 25, 2026: Runoff between Bolsonaro and Lula decides the presidency.

What happens if Bolsonaro wins the runoff?

The Guardian frames the stakes bluntly: a Bolsonaro win raises the prospect of "more fire, more ash, more crime, more death" in the Amazon, and a push of the rainforest "ever more rapidly towards a point of no return," in the outlet's own words describing the four years ahead if Flávio Bolsonaro holds his lead. The article does not cite specific policy proposals Bolsonaro has announced for his potential term, focusing instead on his father's record and the pattern of down-ballot losses for forest-aligned candidates.

For now, the outcome rests on the Oct. 25 runoff. The Guardian notes that international climate and nature campaigners are far more alarmed by the first-round result than domestic coverage suggests ordinary Brazilian voters are — a disconnect the outlet says is central to the current reckoning among those campaigners over why Lula's deforestation gains did not produce a matching electoral payoff on Oct. 7.
