Held at the Brazil Pavilion in the Blue Zone, the event brought together presidents of some of the main public companies linked to the Brazilian government, with moderation by Minister Ester Dweck
The role of public companies in promoting a fairer society in balance with the environment, capable of facing global climate change, was the theme of an event held this Monday afternoon (10th) at the Brazil Pavilion at COP30 in Belém. Organized by the Ministry of Management and Innovation in Public Services (MGI), the panel brought together presidents of some of the main companies linked to the Brazilian government: Itaipu Binacional, Banco do Brasil, Caixa Econômica Federal, BNDES, and Banco do Nordeste.
The companies presented examples of climate actions, ranging from clean energy generation and technological innovations for the energy transition (in the case of Itaipu) to financing solutions for a low-carbon economy, the restoration of degraded agricultural soils, or public works for mitigation and adaptation of cities to more severe and frequent climate events (in the case of the banks).
“We advocate for an efficient and purposeful state,” said Minister Ester Dweck (MGI), who moderated the panel, referring to the strategy of mobilizing state-owned companies to adopt climate goals and contribute to the ecological transition. “There is no ecological transition without an effective state, and it is not possible to deliver this transition without direct or indirect business instruments,” added the minister, who is also a member of Itaipu’s Board of Directors.
During the event, participants signed an open declaration on the role of public companies in promoting a just energy transition and ecological transition. According to the minister, the idea is to engage other countries to adhere to this declaration, stimulating climate mitigation and adaptation actions.
Itaipu’s Director-General, Enio Verri, highlighted the company’s role in the energy security of Brazil and Paraguay, contributing to both countries being among those with the highest share of renewables in their energy matrix. He also emphasized the low cost of energy supplied by Itaipu, the second-lowest tariff in the country, which helps lower electricity bills.

“Itaipu is also at the forefront of the energy transition, contributing with innovations such as floating photovoltaics, biogas, and green hydrogen, in addition to social and environmental initiatives that help increase resilience to climate change,” said Verri.
Also participating in the debate were Banco do Brasil’s president, Tarciana Medeiros; BNDES president, Aloísio Mercadante; Caixa Econômica Federal’s president, Carlos Antônio Vieira Fernandes; and Banco do Nordeste’s president, Wanger Antônio de Alencar Rocha.
