In an effort to encourage shipowners to invest in sustainable practices, the Prince Rupert Port Authority (PRPA) launched the Green Wave Program. Introduced in 2013, the environmental incentive program offers discounted harbour dues to commercial vessels that implement emission reduction measures or other environmental practices.
Through Green Wave, PRPA provides opportunities for shipping companies to reap the benefits of their outstanding environmental performance. Green Wave will incentivize Clean Shipping Index class 3, 4 and 5 with 10%, 20% and 50% discount. Other indices used are RightShip, Environmental Ship Index, Green Marine, Green Award and Energy Efficiency Design Index, as well as multiple underwater noise notations.
