Anew Climate, a US-based biomethane and environmental commodities firm, and LNG and bio-LNG bunker supplier Avenir have completed their first joint liquefied biomethane (bio-LNG) bunkering operation in Europe, at the LNG terminal in Klaipėda, Lithuania, operated by KN Energies.
During the operation, Anew supplied certified waste-based bio-LNG to an Avenir vessel, which then transported the fuel to Sweden for use by Destination Gotland, supporting the decarbonisation of passenger shipping.
The milestone represents Anew’s first bio-LNG bunkering project in Europe, following earlier operations in North America, and signals continued expansion of global bio-LNG supply chains.
Avenir deployed the 7,500 cbm LNG bunker vessel Avenir Ascension for the operation. The vessel is part of Avenir’s fleet of five LNG bunker and supply ships, with two more under construction, and conducts over 200 operations annually in Northwest Europe, primarily in the Baltic region.
The bio-LNG supplied is sourced from Anew’s diversified biomethane portfolio and is optimised for negative lifecycle carbon intensity, while meeting FuelEU Maritime and RED III requirements. The fuel is also fully compatible with existing LNG infrastructure, enabling drop-in use without vessel or bunkering system modifications.
The companies said the partnership combines Anew’s capabilities in biomethane sourcing, certification and compliance with Avenir’s bunkering infrastructure and customer network, allowing scalable delivery of certified bio-LNG to shipowners globally.
With tightening regulations including FuelEU Maritime, RED III, EU ETS and evolving IMO measures, certified bio-LNG is positioned as a near-term, practical decarbonisation pathway that maintains operational continuity.
“Greening shipping is not a future ambition – it is happening today,” said John Cosmo Dwelle, Managing Director at Anew Climate Europe.
“By combining our expanding renewable gas network with Avenir’s maritime infrastructure, we are delivering robust, fully certified Bio-LNG supply chains that are practical, flexibly accessible, and aligned with regulatory requirements. We are proud to launch our first initiative with Avenir as we expand our bio-LNG offering globally.”
“Bio-LNG plays a crucial role in reducing emissions from shipping today,” said Jonathan Quinn, Managing Director at Avenir.
“This transaction with Anew strengthens our ability to deliver reliable, traceable BioLNG solutions, directly supporting our customers as they reduce emissions and progress on their decarbonisation pathways.”
Henry Hammarström, senior energy and climate strategist at Destination Gotland, added: “For 2026, we are increasing Destination Gotland’s use of bio-LNG in order to support FuelEU Maritime compliance of vessels that need support to comply with the greenhouse gas criteria of the regulations through pooling”.
The operation builds on Anew Climate’s earlier progress, including its first bio-LNG loading at the Port of Long Beach in October 2025, as it continues to scale certified bio-LNG bunkering across key global markets.
