Vast Infraestrutura is working to become a driver of decarbonization in the maritime sector by partnering with strategic allies who share its values. One example is the WS Rosalvo tugboat, operated by Wilson Sons, which supports transshipment activities at T-Oil.

In a pioneering move in Brazil, the tugboat was fueled with HVO at the Açu Liquid Terminal (TLA). During operations at T-Oil, it reduces carbon dioxide equivalent (CO2e) emissions by up to 80%, helping to lower Vast’s indirect emissions and overall carbon footprint.

Check out what Eduardo Goulart, Vast’s Commercial Director, has to say about the initiative: “The fact that Wilson Sons’ tugboats are now using a lower-emission biofuel is also very important for Vast. These vessels operate at our terminal and provide logistical support for our STS (ship-to-ship) export operations. In this way, Vast, through its integrated ecosystem of solutions, is able to offer the market a transshipment operation with reduced emissions.”

The publication presents key information about the company’s performance and activities over the past year across environmental, social, financial, and governance areas.

This year, in addition to the guidelines of the Global Reporting Initiative (GRI) 2021 Standard, the report also included sector indicators from the Sustainability Accounting Standards Board (SASB), in an initiative that demonstrates Vast’s maturity and reinforces the company’s ambition to be a benchmark in sustainability and best practices in its segment.

This year, in addition to following the 2021 Standards from the Global Reporting Initiative (GRI), the report also includes industry-specific indicators from the Sustainability Accounting Standards Board (SASB), an initiative that reflects Vast’s maturity and reinforces the company’s ambition to be a reference in sustainability and best practices within its sector.

With T-Oil consolidating its position as the leading oil export terminal in Brazil and the start of operations at TLA, 2024 was a remarkable year for the company, which also made significant progress in its Decarbonization Journey.

But that’s only part of Vast’s story this year. You can read the full 2024 Sustainability Report by clicking this link.

Vast continues to open new horizons for energy.

Aware of its responsibility in the journey toward a lower-carbon world and aiming to better guide its actions in this direction, Vast Infraestrutura has established two priority pathways within its Decarbonization Journey: one focused on developing infrastructure to support vessel electrification, and another dedicated to promoting the use of fuels with a lower carbon footprint in the maritime sector.

The company has been making significant progress on both fronts. Regarding vessel electrification, in addition to the tugboat dock inaugurated at T-Oil in 2024, in partnership with Wilson Sons, and the expansion of onshore power supply for other support vessels, Vast signed a memorandum of understanding this year with the Port of Rotterdam to study the possibilities of electrifying tankers on a global scale.

As for encouraging the use of lower-carbon fuels in the sector, 2025 marked a major milestone: the first-ever maritime fueling operation using HVO in Brazil, carried out at TLA. The use of this fuel, also known as renewable diesel, in the tugboats operating at T-Oil can reduce carbon dioxide emissions by up to 80%, significantly lowering the carbon footprint of Vast’s transshipment operations.

The results achieved so far are a source of pride for the company, which continues to work relentlessly to go further and help build an increasingly sustainable future.

The Wilson Sons tugboat fueled with HVO (Hydrotreated Vegetable Oil) at the Açu Liquid Terminal (TLA) is already operating in oil transshipment activities at T-Oil.

HVO can reduce tugboat carbon dioxide equivalent (CO₂e) emissions by up to 80%, lowering Vast’s indirect operational emissions and overall carbon footprint.

This innovation adds to other initiatives implemented by the company since the start of T-Oil’s activities, a terminal designed with a low-emission profile. In February this year, a study conducted by Vast and Bureau Veritas confirmed that T-Oil operations, carried out in sheltered waters, emit 3x less CO₂e than offshore operations, known as underway.
