MEPC 78/7/19: Proposal for how to calculate Well-to-Wake carbon dioxide equivalent emissions using both GWP100 and GWP20 for comparative purposes as part of the LCA guidelines

This document contains a concrete proposal for how to calculate Well-to-Wake carbon dioxide equivalent emissions from marine fuels using both 100-year Global Warming Potential (GWP100) and 20-year Global Warming Potential (GWP20) for comparative purposes as part of the IMO LCA guidelines
