Navigating Green Seas-Emissions from Marine Fuels_March2024
Navigating Green Seas: Addressing Emissions from Low and Zero Carbon Marine Fuels sets out SGMF’s position on
the challenges presented by low and zero carbon marine fuels and their emissions. An emission reduction culture is proposed for managing fugitive, operational, and emergency releases, as well as fuel combustion emissions. The focus is on aligning maritime practices with global emission reduction targets, integrating an emission reduction culture into ship design and operations.
This paper provides a high-level summary of the principal greenhouse gases (GHG) and pollutants linked to the use of methane/liquefied natural gas (LNG), methanol, ammonia, and hydrogen, discussing their implications for both the environment and human health. In summary, the commitments to mitigate the effects of these fuels include a no-emission approach, addressing all GHG and pollutant emissions, adopting energy-efficient practices, identifying, and measuring emissions, enhancing vessel design, and continuous improvement in onboard practices.
Looking ahead, this paper also serves as a forerunner to future publications that will translate SGMF’s principles into practice. These forthcoming initiatives focus on the different challenges posed by each type of fuel, the progress that has been made so far in emissions reduction, and a roadmap for continuous improvement. The goal is to facilitate the implementation of practical measures on board vessels.
