The Prince Rupert Port Authority has announced four commercial vessel owners recognized for achieving the highest level of environmental performance and participation in 2018 under the Port of Prince Rupert’s Green Wave vessel incentive program. They are COSCO, Maersk, Yang Ming, and BC Ferries. Since 2013, the Prince Rupert Port Authority’s Green Wave program has offered discounted harbour dues to commercial vessels that implement air emission and underwater noise reduction measures. Using a three-tier criteria system, vessels are scored for their level of achievement in one of the recognized environmental programs or for technological advancement. Participation in the program is entirely voluntary.
