Share this article Decarbonization is indeed “a thing”, as Millennials might say. The problem that I have writing on the topic- and presumably that readers have, is that the timeframes can be very lengthy, like 30 years out. Indeed, many promising technologies for achieving shipping’s ambitious reduction targets for carbon emissions are on the drawing boards. But they are not yet there- nor is it clear who will pay for them. The International Maritime Organization (IMO) concluded a two day seminar on decarbonization for shipping; happily, the well-organized (virtual) event strived for practicality. There is an important and proactive role for the IMO to play here, going way beyond its traditional regulatory and safety roles.
