One of the arguments voiced against LNG fuelling is that while it eliminates SOx emissions, reduces particulates to virtually zero and emits 90% fewer NOx emissions than existing heavy fuel oil, it still emits CO2.

But just how clean is gas overall for use in the marine world?

The Society for Gas as a Marine Fuel (SGMF), in partnership with industry coalition SEA\LNG, is paying for an independent, reference piece of research to be done to determine what the emissions profile will be for gas as a marine fuel.
