FURTHER CONSIDERATION OF THE DEVELOPMENT OF THE BASKET OF CANDIDATE MID-TERM GHG REDUCTION MEASURE(S), USING ANNEX 1 TO DOCUMENT MEPC 82/WP.9 AS THE BASIS
Analysis of the proposed ππππ correction factor in the GFI-attained equation and adjusted tank-to-wake (TtW) emissions accounting methodology in document ISWG-GHG 17/2/7 and analysis of the required Remedial Unit prices
Submitted by CSC
This document examines the implications of incorporating an π π£ππ¦ correction factor and adopting the adjusted tank-to-wake (TtW) GHG accounting methodology under the Global Fuel Standard (GFS) as proposed in document ISWG-GHG 17/2/7 (Angola et al.). Instead, this document underscores the importance of maintaining the integrity of the GFS by avoiding correction factors that could narrow its scope. Ensuring that the required GFIs are based on a complete well-to-wake (WtW) GHG emissions accounting system will also guarantee a level playing field among fuel types and avoid the need to make the “Z factors” even more stringent to compensate for otherwise unabated emissions. Lastly, this document argues that sufficiently priced Remedial Units (RUs) are needed to ensure that the uptake of alternative fuels remains the most cost-effective option for compliance with the GFS and sets out a methodology to estimate the minimum necessary prices to do so.
