Understanding Net-Zero, Near-Zero, Absolute Zero, and Zero (ISWG-GHG 13/3/9)

Submitted by the WSC to ISWG-GHG 13

This paper discusses four terms (net-zero, near-zero, zero, and absolute zero) frequently used in GHG-related discussions in the IMO and other fora. The paper is tabled to promote greater clarity in the use of these terms and a better understanding of what GHG emission reductions can be expected with the use of certain fuels (many of which are commonly referenced as potential fuels to be used in the maritime sector) when produced using 100% renewable energy. We also highlight the important role of renewable energy in the production of certain fuels and why this is critical to achieving a major energy transition with minimal GHG emissions.
