March 29, 2023 | Circular No. 11510

Dear Member,

Below is an updated summary of environmental incentive programs Canadian ports have established to reward “green vessels.” The scope of these programs varies. However, each of these ports offers discounted harbour dues to vessels that meet certain environmental standards. Such standards include the use of “green technologies,” cleaner fuels, and/or certification under various ship environmental programs.

Since our last update on such programs via CL 11428 in 2022, the Port of Saint John has created a new incentive program, the Port of Vancouver and the Port of Halifax have added tiers to their programs with higher rebate levels, and ports have added ways to qualify for their programs. Changes since CL 11428 are indicated in italics below. This information can also be found on the member’s section of our website under the ‘Environment’ tab and as a .pdf HERE.


Port of Vancouver A vessel may qualify for one of three levels of rebates, depending on the vessel’s environmental performance:

  • Bronze: 23%
  • Silver:   35%
  • Gold:  47%
  • Platinum: 75%
A vessel may qualify for discounted harbour dues under one of the four categories (bronze, silver, gold, platinum) based on several criteria, including:

  • Use of “cleaner fuels” (e.g., natural gas, biodiesel, hydrogen)
  • Technologies reducing emissions: (e.g., wind assist, battery assist)
  • Vessel and Engine Technologies- above regulatory requirements, e.g., connecting to shore power, underwater noise reduction, shore power, NOx Tier III Engine.
  • Participation in a ship environmental program: Environmental Ship Index (ESI), RightShip, Clean Shipping Index, Green Marine, Energy Efficiency Design Index (EEDI), Green Award, and the Clean Cargo Working Group program
  • Environmental notations from ship classification societies (American Bureau of Shipping (ABS), Bureau Veritas (BV), China Classification Society (CCS), Det Norske Veritas-Germanischer Lloyd (DNV-GL), Korean Register, Lloyd’s Register (LR), and Registro Italiano Navale (RINA).

Application can be made on a ship call basis or through an annual declaration
