In the past, many studies have demonstrated different greenhouse gas (GHG) impacts from the use of liquefied natural gas (LNG).
In theory, when using emission and energy coefficients in combustion only, LNG results in about 25% lower GHG emissions than diesel (MGO) or bunker oil (HFO).
However, larger well-to-tank (WTT) emissions for the LNG supply chain as well as uncombusted methane (CH4) from the ship's engine might more than nullify any GHG gains.
