Brazil’s state-controlled oil giant Petrobras has named a new leader for its Petrobras energy transition strategy, approving William Vella Nozaki as interim Executive Director of Energy Transition and Sustainability. The board decision on July 24, 2026 places a long-time academic and union-linked figure at the helm of the company’s low-carbon ambitions, effective August 1.
Who Is William Vella Nozaki?
William Vella Nozaki is not an outsider to Petrobras or its energy transition agenda. He has held the position of Executive Manager of Integrated Energy Transition Management at the company since August 2024.
The board’s decision therefore represents an internal promotion within the same directorate rather than a fresh external appointment.
His professional background is rooted in academia and the labor movement. Nozaki studied Social Sciences at the University of São Paulo (USP) and earned a master’s degree in Economics from the State University of Campinas (Unicamp).
He formerly served as a director of Ineep, a research institute linked to the FUP, Brazil’s national oil-workers union federation.
Reporting in the Brazilian press consistently ties Nozaki to the political network of President Luiz Inácio Lula da Silva. He participated in Lula’s government transition team and is described as having strong links to the PT, the president’s Workers’ Party.
This political alignment is a key part of the context for his appointment.
The Petrobras Energy Transition Portfolio
The Executive Directorate of Energy Transition and Sustainability is one of Petrobras’s core executive areas, sitting alongside industrial operations in the company’s management structure. Its remit covers the company’s entire low-carbon project pipeline and its broader decarbonization agenda.
Petrobras’s own materials list the unit as central to balancing traditional oil and gas investment with diversification. The portfolio includes projects in ethanol production, carbon capture, use and storage (CCUS), and low-carbon hydrogen. These technologies form the backbone of the company’s stated plan to remain a major energy player while reducing its emissions footprint.
Reuters and other outlets have reported that the directorate is expected to announce new transition-related investments in the second half of 2026. Ethanol-related initiatives are specifically cited among the upcoming project pipeline.
The appointment of a permanent or interim leader for this unit is therefore a signal to investors about the company’s strategic direction.

A Strategy Aligned with Lula’s Energy Policy
The appointment fits squarely within President Lula’s broader energy policy framework. Since returning to office in 2023, Lula has emphasized a stronger state role in energy planning and industrial policy.
His administration frames the energy transition as a “just” one, meaning it must protect workers and use state-controlled enterprises like Petrobras as engines of development.
Nozaki’s union and development-policy credentials are consistent with this political framing. His background at Ineep and his ties to the FUP signal that the transition directorate will operate with close attention to labor interests and national industrial strategy.
For foreign investors, this reinforces that Petrobras’s low-carbon push will not be a purely market-driven exercise.
The decision to keep the directorate under the control of a PT-linked figure also reflects internal government dynamics. Brazilian media reported in mid-2025 that the role would remain within the party’s sphere of influence, following earlier disputes over executive appointments at the company.
What This Means for Foreign Investors
For expatriates and international investors following Brazil’s state-controlled oil giant, the appointment provides clarity on the leadership of a strategically vital unit. The energy transition directorate is the main channel through which Petrobras plans to allocate capital to low-carbon projects, making its leadership a key variable for anyone assessing the company’s long-term trajectory.
The interim nature of the appointment is worth noting. Nozaki takes the role on an interim basis from August 1, 2026.
It remains unclear when or if a permanent director will be named. This introduces a degree of uncertainty into the governance of the unit, though the internal promotion suggests continuity in the short term.
Investors should also weigh the political dimensions. Nozaki’s ties to the PT and the union movement mean the directorate will likely prioritize projects with strong domestic industrial linkages, such as ethanol and hydrogen produced with Brazilian feedstock.
This could shape the pace and nature of capital expenditure in the transition portfolio.
Petrobras’s Low-Carbon Project Pipeline
Petrobras has publicly positioned its energy transition unit as central to its project pipeline for the coming years. The company is studying or developing initiatives in several key areas.
Ethanol projects are a notable focus, leveraging Brazil’s vast sugarcane industry and existing biofuel infrastructure.
Carbon capture, use and storage represents another pillar. Petrobras already operates one of the world’s largest CCUS programs in its pre-salt oil fields, reinjecting CO2 into reservoirs.
The transition directorate is expected to expand these efforts. Low-carbon hydrogen, produced from natural gas with carbon capture or from renewable sources, rounds out the main technology focus areas.
A memorandum of understanding signed with Findes, the Federation of Industries of Espírito Santo state, covers cooperation on CCUS and low-carbon hydrogen production. Such partnerships are likely to multiply under the new directorate’s leadership as Petrobras seeks to build a project portfolio that satisfies both its commercial mandate and the government’s industrial policy goals.
Board Approval and Next Steps
The board’s approval on July 24, 2026 formalizes a decision that had been anticipated in Brazilian media for weeks. Outlets such as Brasil 247 and Portal Tela had reported on the succession process for the directorate, noting the political negotiations involved.
Nozaki assumes the role on August 1. The company has not announced a timeline for naming a permanent director.
For now, the interim appointment ensures that the energy transition unit has a named leader as Petrobras moves into a period of expected project announcements in the second half of 2026.
The appointment completes a process that saw earlier attempts by Petrobras’s CEO to fill other executive positions face resistance, according to reporting by O Globo’s Malu Gaspar. The energy transition directorate, by contrast, appears to have been resolved with less public friction, preserving the PT’s influence over this politically sensitive portfolio.
