Wallenius Sol joins Gasum’s FuelEU Maritime pool as compliance generator

10 October 2025 | Helsinki — Finnish energy company Gasum has entered into a cooperation agreement with shipping firm Wallenius Sol, under which Wallenius Sol’s dual-fuel vessels will join Gasum’s FuelEU Maritime pool as compliance generators. The vessels will run on bio-LNG, generating compliance surpluses that can be used to support other ships in meeting FuelEU Maritime requirements.

Wallenius Sol operates regular services between ports in northern Finland, Sweden, Germany, the Benelux region, and the United Kingdom, transporting trailers, containers, and project cargo for industries such as paper and steel.

Through this collaboration, Wallenius Sol’s customers will benefit from low-emission transport services, while contributing to the wider maritime industry’s decarbonisation goals under EU climate regulations.

FuelEU Maritime pooling to ease compliance costs

Under the FuelEU Maritime regulation, which came into force this year, shipowners operating in EU waters must reduce the carbon intensity of their fuel by at least 2% compared to 2020 levels. Companies failing to meet this target face significant penalties.

Pooling allows operators to share compliance obligations, with vessels running on renewable fuels generating surplus compliance credits that can offset deficits from others. Gasum manages the FuelEU pool, ensuring balance through the year, while classification society DNV verifies compliance at year-end.

“We are very excited that Wallenius Sol has decided to join our FuelEU Maritime pool, as this collaboration enables us to open even more regulation surplus to shipowners at this pivotal point,” said Jacob Granqvist, Vice President, Maritime at Gasum.

“The window for securing compliance for 2025 is closing rapidly and the available capacity may run out before the year end. Pooling is a brilliant and easy opportunity for all maritime actors to join forces in lowering emissions from the industry together.”

Bio-LNG to support low-carbon operations

Rebecca Tagaeus, Chief Sustainability Officer at Wallenius Sol, said the partnership aligns with the company’s roadmap for low-carbon logistics.

“We aim to be the natural partner for sustainable sea logistics in the Gulf of Bothnia and across the European continent. Together with Gasum, we are scaling the use of renewable gases at sea. Switching to bio-LNG for our Enabler-class vessels is clear proof that our roadmap is delivering – and that we are investing in our customers’ climate goals while accelerating the green transition across the Nordics.”

Gasum noted that liquefied biomethane (bio-LNG) — a fully renewable biofuel — can reduce lifecycle greenhouse gas emissions by up to 90% compared with conventional marine fuels such as marine gas oil (MGO).

The company said it remains committed to increasing the availability of renewable gases to help the maritime industry transition to low-carbon operations, while providing practical mechanisms like pooling to manage compliance costs efficiently.
