Optimizing ship arrivals at congested ports could cut emissions by up to 25%, study finds.
A new study by University College London and the University of Massachusetts Amherst shows that optimizing ship arrivals at ports, considering factors like congestion, could cut voyage emissions by up to 25% for some vessel types.
The research found average emissions savings of around 10% for container ships and dry bulkers, 16% for gas carriers and oil tankers, and 25% for chemical tankers.
Ships spend about 4-6% of their time waiting at anchor outside ports, a figure that rose due to post-pandemic trade surges and port congestion.
The study suggests regulations should consider the entire voyage to encourage emission reductions.
