“ We ’ re already seeing a shift to more-sustainable shipping ,” he says . “ This is reflected in the carriers ’ order books for more dual-fuel ships , which are beginning to make up a greater proportion of new vessels .”
He also points out the Chinese State Shipbuilding Corporation reported recently that 31.6 % of vessels completed in 2022 were dual-fuel ships . Although sea cargo businesses have a couple of years ’ grace , Hersham says the regulations determining acceptable levels of emissions will grow tougher year-onyear , “ meaning that the pressure on less efficient vessels will continue to grow ”.

“ Some biofuels , such as dimethyl ether , require no extensive modifications to engines , and are the most ready lowemissions fuel option ,” he says .
