Who is Marina Silva?
Marina Silva was born in 1958 in Acre. She was a city councillor, state deputy and, from 1995 to 2011, a senator, and she served as Lula's Environment Minister from 2003 to 2008. She left the PT in 2009 and ran for president in 2010, 2014 and 2018, then founded REDE. Elected federal deputy for São Paulo in 2022, she returned as Environment and Climate Minister in January 2023. On 1 April 2026 she left the ministry to run for the Senate in São Paulo for the PSOL-REDE federation. On 4 October she finished fourth, with about 7.86 million votes and 18.12 percent of valid votes, behind the winners Guilherme Derrite and André do Prado and Simone Tebet.

Record
Her second ministry coincided with three straight annual falls in Amazon deforestation, according to INPE's Prodes system. Disputes also marked it: Ibama's 2023 refusal of Petrobras drilling near the Amazon river mouth, which she defended as technical, and the environmental licensing law, where she said her ministry worked on Lula's 63 vetoes while the Special Environmental Licence stayed in the text.
Supporters point to the deforestation figures and say the environmental agenda is a priority across the government, as she has put it. In the 2026 campaign Flávio Bolsonaro said the government held records of environmental degradation, a claim she rejected with INPE data.
In their words
