Shipping Shown Path to Halve Emissions This Decade

The global shipping industry can reduce emissions by nearly 50% by the end of the decade, according to a new study by CE Delft. These findings come as the International Maritime Organization (IMO) is about to reach an agreement on climate targets to reduce greenhouse gas emissions from ships in July.

The analysis shows that ships can achieve 36-47% emissions reduction by 2030 compared to 2008 levels by deploying 5-10% zero or near-zero emission fuels, wind-assist technologies, and by “climate optimising” the speed of ships.

The emission reductions would require a speed reduction of 20-30% relative to 2018, the study suggests.

Implementing these measures would increase shipping costs by 6-14% on average, the study claimed, arguing that these costs would be manageable, a sum that would be dwarfed by the cost of climate related damages to the industry and wider society if shipping fails to cut emissions.

University College London estimates that every year of inaction this decade will add an extra $100bn to the cost of shipping decarbonisation.

The study was commissioned by Transport & Environment, Seas at Risk, Ocean Conservancy and Pacific Environment.

John Maggs from Seas At Risk said: “The science is crystal clear, emissions from shipping have to halve by 2030 if we are to stand any chance of keeping warming below the Paris Agreement’s 1.5°C temperature limit. What was less clear until now was if this was possible without impacting trade. Now we know not only that it is possible and shipping has a clear pathway to halving its climate impact by 2030, but that it can do so at minimal cost.”

Faïg Abbasov from Transport & Environment added: “Waiting until 2050 to decarbonise is a bit like waiting until your house burns down before you call the fire brigade.

This would be irresponsible and disingenuous. Science says halving emissions by 2030 is technically possible, and costs are manageable.”
