This document proposes that the Working Group recommend the Committee to re-establish the correspondence group on other social and economic sustainability themes/aspects of marine fuels at MEPC 84. It provides potential terms of reference for the same. 

This document comments on the GESAMP-Ballast Water Working Group report by sharing a new study on ballast water operations, discharges and their impacts in the Gulf of California (GoC) from future liquefied natural gas (LNG) tanker traffic.

This document provides comments on document LEG 113/14 and examines the current lack of an international liability and compensation framework for emerging marine fuels and highlights the misclassification of fossil-based fuels such as LNG and LPG as alternative fuels. 

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. 

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 (2024 LCA Guidelines). By focusing on LNG, bio-LNG, and e-LNG as an example in this document, 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.
