The IMO’s fourth greenhouse gas study has shown that the “sector’s methane emissions increased by 150% in the six-year period because of the increased deployment of LNG-fuelled ships”. The tradeoff for methane instead of carbon dioxide could end up being counter productive if it is included in the next phase of the EEDI.
Does this report spell a decline in newbuild LNG fuelled vessels? Is there still a marked benefit in using LNG as a marine fuel?”
