Since 2010, the Port of Amsterdam has offered discounts on port dues to vessels listed in the Environmental Ship Index (ESI) that have attained a rating of 20 points or higher. As of 1 August, the port has doubled this incentive for vessels that have an ESI certificate and use LNG for their main or auxiliary engines.
To further encourage use of the fuel by its customers, the Port of Amsterdam aims to have an LNG bunker pontoon in place by the end of this year. While the port does not have any set emissions or pollution-reduction targets, it does hope to encourage the 50,000 vessels that call in Amsterdam annually to operate “as rapidly and efficiently as possible, using the least amount of resources.”
“LNG emits significantly smaller quantities of particulate matter than other fuels, as well as producing less carbon dioxide,” says a statement from the port. “Port of Amsterdam regards LNG as a vital transitional fuel which currently serves as the best alternative for the shipping industry.”
The ESI was designed by the ports of Le Havre, Bremen, Hamburg, Antwerp, Rotterdam and Amsterdam. The index expresses the environmental performance of vessels in terms of the emission of nitrogen and sulphur oxides (NOx and SOx), as well as CO2.
The performance is measured on a scale of 0 to 100, whereby a score of 1 already indicates an improvement in relation to the current environmental regulations for shipping, while 100 is exceptional.
