Brazil runoff puts Amazon policy in focus as candidates set different deforestation targets
The story at a glance
Brazil’s presidential runoff, scheduled for 25 October, pits Luiz Inácio Lula da Silva against Flávio Bolsonaro. Their programmes set different goals: Lula pledges net-zero deforestation by 2030, while Bolsonaro promises to end illegal deforestation by 2029. These are not equivalent measures.13
The choice comes as recorded deforestation in the Brazilian Legal Amazon has fallen, but the election alone cannot determine what happens to the forest. Enforcement, Congress and economic pressures will also shape policy, while projections of ecological tipping risks remain uncertain.12
The story in brief
What you need to know
- The campaign targets address different things and timelines. Bolsonaro’s programme promises zero illegal deforestation by 2029; Lula’s is a net-zero deforestation pledge for 2030. Neither target, by itself, establishes how much forest loss will occur or how it will be measured.13
- Bolsonaro’s programme includes satellite monitoring and coordinated enforcement measures, alongside a proposal to speed environmental licensing. It says a licence would be granted if an authority did not decide within a specified period, making implementation details consequential.3
- The new Congress may influence forest policy beyond the presidency. Bolsonaro’s party won 121 seats in the House, and a Sumaúma analysis cited by Grist said about half of incoming House members had supported loosening environmental licensing and limiting Indigenous land claims.1
- Lower annual clear-cutting totals do not capture every pressure on forest condition. Reporting cited in the research notes that forest degradation and other pressures should not be inferred from deforestation figures alone.2
- Warnings about possible policy rollback under a Bolsonaro presidency are assessments, not established outcomes. The reporting also points to constraints from Congress, export markets and investment, as well as the candidate’s stated commitments to address illegal deforestation.123
Conservation context
Why this matters
The result could affect how forest rules are enforced and how environmental licensing is handled. But campaign promises are not the same as funded, enforceable policy, and a national deforestation total cannot on its own describe the wider condition of the Amazon.123
The developing story
What happens next
Voters are due to choose between Lula and Flávio Bolsonaro on 25 October. After the runoff, the key test will be how the winner translates campaign commitments into policy, and how Congress shapes decisions on enforcement, licensing and Indigenous land claims.123
Established evidence
What we know
- The first-round vote took place on 4 October, with Lula and Flávio Bolsonaro advancing to the runoff scheduled for 25 October.1
- Official INPE figures put deforestation in the Brazilian Legal Amazon at 5,731 km² in 2025, 12.07% below the 2024 figure.2
- The Bolsonaro programme proposes satellite-based monitoring and coordination between agencies, as well as faster environmental licensing.3
Open questions
What we don't know
- The reporting does not establish whether either candidate would turn campaign commitments into funded, enforceable policies, or how implementation would differ from the written programmes.123
- The extent of the new Congress’s influence over licensing, Indigenous land claims and forest enforcement remains unresolved.12
- The supplied reporting identifies uncertainty around tipping-point estimates, including their assumptions and sensitivity to warming and forest degradation as well as deforestation. It does not establish a settled threshold or date.1
- How fire, drought, logging and other degradation pressures will affect forest condition independently of annual clear-cutting totals remains an open question in the research.2
