From the 1st of January, 2016, Green Award certified inland barges receive a 15% discount on the harbor dues in Nijmegen. Ships holding a Green Award certificate are cleaner, produce less noise and have higher fuel efficiency. With this action the largest inland port of the Netherlands stimulates further development of sustainable shipping. The Port of Nijmegen is now a participant of the Green Award scheme – an international certification scheme that already unites 16 inland ports and 573 inland ships.
