Relatively low-cost measures could cut emissions from shipping by up to nearly 50% by the end of this decade, according to a report from established shipping analysts CE Delft.

Ships could achieve 28% to 47% emissions reductions by 2030, compared to 2008 levels, by deploying 5% to 10% zero or near-zero emission fuels, wind-propulsion assistance technologies where possible and reducing the speed of vessels, said the report commissioned by Transport & Environment, Seas at Risk, Ocean Conservancy and Pacific Environment.
