The most environmental friendly vessels who have a port call at North Sea Port can get a discount on their port dues, as stated in our Tariffs, based on their Environmental Ship Index (ESI) Score. Making our port dues 'Green' fits in the efforts of North Sea Port as a sustainable port.
ESI, founded in 2011 by the International Association of Ports and harbors (IAPH), is a voluntary index which rates vessels that are above compliant in reducing air emissions.
Scores are given based on NOx-, SOx-, CO2emissions and the presence of a shore power connection onboard.
North Sea Port is an Incentive Provider of ESI.
On the website of ESI you can find more information on ESI.
One of the conditions to qualify for this discount is that this must be reported in writing to North Sea Port at the latest with the declaration of port dues.
