London - A new study by UCL and UMAS has found that optimising port arrivals to consider port congestion or waiting times could reduce voyage emissions by up to 25 per cent for some vessel types.

The average potential emissions saving for the period considered (2018-2022) was found to be approximately 10 per cent for containerships and dry bulkers, 16 per cent for gas carriers and oil tankers, and almost 25 per cent for chemical tankers.

The study found that these ships spend between 4-6 per cent of their operational time, around 15-22 . . .
