The port of Antwerp wiil reward “clean ships” with a 10 percent discount on tonnage based harbor dues from July 1 in a bid to further cut emissions of pollutants.
To qualify for a discount a ship has to score 31 or more points on an Environmental Ship Index, which rates vessels on a scale from 0 to 100 based on factors such as fuel consumption and emissions including sulphur dioxide and carbon dioxide.
By the Numbers: U.S. Trade with Spain.
The port authority will guarantee the discount for at least three years to incentivize ship-owners to improve the ESI score of their vessels.
The discount follows an initiative by the International Association of Ports and Harbors, which led the port authorities of Le Havre, Bremen, Hamburg, Rotterdam, Amsterdam and Antwerp to introduce the ESI.
So far more than 250 ships have been given an ESI score.
The participating port decides individually how to reward vessels that meet the green target.
