Executive Summary

 This document comments on the report of the third meeting of GESAMP-LCA WG, regarding the development of a default well-to-tank (WtT) emission factor for fossil LNG. It highlights systematic underestimation of upstream emissions in life cycle assessments, cautions against adoption of non-representative or supplier-specific factors, and calls for a conservative, globally representative default value consistent with established benchmarks. It also provides alternative emission factors. 

Maritime Beyond Methane

Maritime Beyond Methane (MARBEM) is a global initiative accelerating the shipping industry’s transition beyond methane-based fuels (fossil, bio-, and e-LNG). We provide clarity on the policies, players, and emerging technologies shaping maritime decarbonization—equipping policymakers, financiers, and industry leaders with the data and practical pathways needed to advance a future-ready shipping industry.
