4、uctionThe challenge of maritime decarbonisation is not that it is happening,but that it needs to happen so quickly.The evolution of sail to its heyday of the great tea clippers took centuries,and the transition to coal-powered steam ships was driven by greater supply chain mobility and speed.The arr

5、ival of diesel-fuelled engines led to a new type of ship propulsion and power generation,but this has taken close to one hundred years to evolve to where they are today.Each shift had a dramatic impact on the cost,speed and efficiency of shipping.The energy transition that the maritime industry face

6、s today is distinct from those earlier evolutions.It is not driven solely by technological advances or economics,but by an environmental imperative,increasingly underscored by social pressure,policy,and regulatory demands to reduce emissions.Decisions are being made today with some commercial uncert
