Improving the energy efficiency of new ships is an obvious first step in tackling shipping’s contribution to the climate crisis.

While the International Maritime Organisation (IMO) agreed a design standard for new ships in 2013, it did so using a baseline and targets that lack ambition and that designers and builders have easily been able to meet. For example, the 2015-2019 standard only requires ships to be as efficient as they were in 1990! Without regulation ship design efficiency goes up and down with the economic cycle and with fuel prices.

If the IMO’s ship design efficiency requirements are to play a proper role in reducing shipping’s climate impact then new more ambitious efficiency standards are required that drive innovation and chart a path to the necessary long-term decarbonisation of the fleet.

Working with partners Transport & Environment, Seas at Risk has commissioned the following studies looking at ship design efficiency:
