ISWG-GHG 21-INF.2 – Work programme developed to confirm robustness and reliability of methods proposed for calculating wind propulsion in the attained GFI calculation
This document has been submitted by IWSA for the Intersessional Working Group held in April 2026, ahead of the MEPC 84 session. This document presents the work programme developed by wind propulsion experts to further refine, update and validate the robustness and reliability of the methods proposed in documents MEPC 82/7/9, MEPC 83/7/33 and MEPC 83/INF.33 by IWSA. These methods quantify the share of energy provided by the direct use of wind propulsion technologies onboard vessels, with the purpose of integrating these methods into the calculation of the GHG Fuel Intensity (GFI). Its purpose is to keep the maritime community and Member States updated on the current maturity of these methods and on the progress on delivering available case studies in order to reaffirm and demonstrate the efficacy of these methods.
