Vessels that score well on the Environmental Ship Index (ESI), a new international standard for ship emissions, will receive discounts on their dues at major Dutch ports.

Designed by the ports of Le Havre, Bremen, Hamburg, Antwerp, Amsterdam and Rotterdam, the ESI is a certificate that will be awarded by the World Port Climate Initiative upon request. The index shows the environmental performance of ships in terms of the emission of air pollutants (NOx and SOx) and CO2. Ports and other nautical service providers throughout the world can use the index to reward ships and, in this way, encourage sustainable behaviour in the shipping industry.

Making port tariffs greener and rewarding clean ocean-going vessels are ways to promote sustainable development. The ports of Amsterdam, Moerdijk, Dordrecht and Rotterdam will be the first to start using the ESI to reward clean ships. Antwerp, Hamburg and Bremen have also announced their intention to use the ESI.
