Green Marine is an environmental certification program for the North American marine industry. Impression

First initiated by the St. Lawrence and Great Lakes marine industry, the program encourages companies to implement concrete and measurable actions to reduce their environmental footprint beyond regulations.

What makes this program unique is the fact that is was developed in collaboration with different stakeholders caring about protecting the river: the marine industry, the federal and provincial governments, environmental groups and academics.

The result is a program that allows its subscribers – ship owners, ports, terminals, the St-Lawrence Seaway, as well as shipyards, to measure their environmental footprint and to continually improve their performance with regards to a growing number of priority issues:

Performance indicators:

For ship owners:

  • Oily water
  • Pollutant air emissions – NOX
  • Pollutant air emissions – SOX and PM
  • Aquatic invasive species
  • Greenhouse gas (GHG) emissions
  • Garbage management
  • Cargo residues
  • Underwater Noise

For Ports, terminals and shipyards:

  • Community impacts
  • Dry bulk handling and storage
  • Greenhouse gas (GHG) emissions
  • Environmental leadership
  • Spill Prevention
  • Waste management
  • Underwater Noise

Ongoing improvement:

For each applicable indicator, the environmental performance is evaluated on a scale from 1 to 5 according to criteria that are specific to each level.  Level 1 requires monitoring of regulations, while level 5 stands for excellence and leadership.

Requirements for receiving Green Marine certification:

  • Company based or operating in Canada or in the United-States
  • Annual self-evaluation of the company’s environmental performance by using specific guides
  • Annual publication of individual results
  • Third party verification of results every two years

Green Marine is the most complete, inclusive and transparent program that exists for the marine industry. It counts more than 100 participants, 80 partners, 20 associations and 60 supporters.

Supporters are environmental groups and government departments/agencies that have endorsed the program and encourage and support the sustainable development initiative undertaken by the marine industry.

Since the implementation of the program in 2007, the industry has significantly increased its environmental performance despite a stringent regulatory framework and the continuous strengthening of the program requirements. The ultimate goal is to lead the industry towards environmental excellence through continuous improvement.
