Shipyards build up to the challenge of launching a zero-emission fleet

A huge part of the world fleet will have to be replaced with zero-emission vessels in little more than two decades if regulators set a goal of decarbonising shipping by 2050.

The industry will have to start the transition to zero-emission ships by around 2030 at the latest to have any hope of decarbonising in time, according to government submissions to the International Maritime Organization.
