Much thought is being put into how to decarbonise shipping. Governments are working with industry and academia to come up with ­regulatory and technical solutions to facilitate the transition towards net zero.

But the assumption seems to be that the industry can continue with business more or less as usual.

For now, hope suffuses the debate.

Hope that the IMO will take decisive steps to implement its strategy. Hope that governments will introduce regulatory frameworks and carbon taxes.

Hope that researchers and manufacturers will find ways to produce green hydrogen and ammonia on a global scale and at a competitive price.
