19 Apr Updated Independent 2021 Lifecycle GHG study
SEA-LNG and SGMF commissioned an update to the Lifecycle GHG Emission Study on the use of LNG as a Marine Fuel. Conducted to stringent ISO standards by independent specialist consultants, Sphera (formerly thinkstep), the study is peer-reviewed by a panel of internationally-recognised academic experts.
The research updates and supports the findings from the previous thinkstep study, widely recognised as the definitive view of lifecycle emissions analysis of the use of LNG as a marine fuel. It reinforces the fact that LNG is the only operationally-proven marine fuel available today, and for the foreseeable future, which significantly reduces GHG emissions for deep-sea shipping.
LNG is the only operationally proven and scalable marine fuel that offers immediate reductions NOW in GHG and local emissions.
• The use of LNG as a marine fuel shows GHG benefits of up to 23% on a Well-to-Wake (WtW) basis and up to 30% on a Tank-to-Wake (TtW) basis compared with current oil-based marine fuels
• LNG provides a major advantage in terms of improving air quality and human health, particularly important in ports and coastal areas
Methane emissions outlook shows significant improvements by engine manufacturers and LNG suppliers
The study confirms the 1st GHG study conclusion that LNG provides a significant advantage in terms of improving air quality which is particularly important in ports and coastal areas. Beyond the benefits asso- ciated with reducing air pollutants, LNG provides reduced GHG emissions from international shipping and does contribute to the International Maritime Organization (IMO) GHG reduction targets.
