Aligning global ambition with maritime leadership.
Actionable insights and practical pathways to advance the future of shipping beyond methane.
Leveraging a broad network of experts to translate complex, cross-sector data.
Methane-based fuels, including fossil, bio, and e-LNG, are the main source of methane emissions in the maritime sector. To limit warming to 1.5°C, countries must reduce methane emissions by a third by 2030 and almost halve them by 2050.
We bring clarity to the policies, players, and pathways shaping the maritime decarbonization beyond methane.

Navigating the Transition
Maritime Beyond Methane (MARBEM) helps strengthen regulatory frameworks that drive credible, evidence-based action on maritime decarbonization.
ISWG-GHG 20/3/7: Intersessional Meeting of the Working Group on Reduction of GHG Emissions from Ships, 20th Session
ISWG-GHG 20/3/7: This document encourages the re-establishment of the correspondence group looking at "other social and economic sustainability themes/aspects of marine fuels" for potential inclusion in the 2024 Guidelines on life cycle GHG intensity of marine fuels.
By focusing on LNG, bio-LNG, and e-LNG as examples, it is evident that without a comprehensive assessment of existing and emerging fuels, IMO's net-zero goals and the implementation of the IMO Net-Zero Framework could be under threat.
ISWG-GHG 20/3/9: Intersessional Meeting of the Working Group on Reduction of GHG Emissions from Ships, 20th Session
ISWG-GHG 20/3/9: This document shares the findings of a literature review and summary report on the well-to-tank (WtT) GHG intensity of liquefied natural gas (LNG).
The literature review referenced in this document can be found here, published by Energy and Environmental Research Associates, LLC on September 3, 2025.
Op-Ed: The Great LNG Scam: The IMO’s Climate Credibility is on the Line
The Directors of Equal Routes—a member of MARBEM—write for Splash ahead of this month’s Net-Zero Framework vote at the International Maritime Organization.
The cost advantage, reinforced by the industry’s short-term cost optimisation strategies, is expected to sustain the increase of LNG-fuelled ships unless governments step in with clear policies to counter this trend.
