ISWG-GHG 17/2/20: Further information on the GHG Fuel Standard (GFS) and the incorporation of fuel and non-fuel on-board energy reward factors

A sustainable fuel sub target, and associated proposed amendments to documents ISWG-GHG 15/3/1 and ISWG-GHG 16/2/7

ISWG-GHG 17/2/20: Further information on the GHG Fuel Standard (GFS) and the incorporation of fuel and non-fuel on-board energy reward factors, a sustainable fuel sub target, and associated proposed amendments to documents ISWG-GHG 15/3/1 and ISWG-GHG 16/2/7

This document provides elements to consider in designing the GHG Fuel Standard (GFS), especially in relation to the GHG Fuel Intensity (GFI) targets, the competitiveness of alternative fuels and non-fuel technologies, and what constitutes a sustainable zero and near-zero emission fuel. Concretely, this document suggests the incorporation of dedicated mechanisms to promote non-fuels on- board energy sources (e.g. wind and solar) as well as sustainable marine fuels based on electrolytic-hydrogen. It provides draft amendments to modify the proposals contained in the annex to document ISWG-GHG 15/3/1 (Austria et al.) as well as in annexes 1 and 2 to document ISWG-GHG 16/2/7 (Austria et al.) in order to operationalize the aforementioned mechanisms.

The Guardian: US ‘bullying’ could scupper carbon levy on shipping, warn experts

“The net zero framework [which underlies the carbon levy] may not be perfect, but it has the potential to grow into a set of rules that would allow the IMO and shipping industry to meet their climate and environmental justice commitments.”
