Born of a collective industry effort in 2007, Green Marine aims to guide the maritime industry towards environmental excellence by encouraging maritime enterprises to adopt concrete measurable actions that go beyond regulatory obligations. The program therefore deals specifically with issues related to maritime transportation, such as the quality of air, water and soil, as well as community relations.

It is an inclusive, rigorous and transparent initiative that brings together several types of participants: ship owners, ports, terminals, shipyards, and the Seaway corporations based in Canada and the United States. To obtain Green Marine certification, participants must complete the certification process. The membership also encompasses associations, supporters and partners that each in their own way support participants in their efforts to reduce their environmental footprint.

MARIN is a Green Marine supporter. Green Marine supporters both support and encourage the sustainability initiative being undertaken by the maritime industry. These environmental groups, scientific institutions, and government agencies help to shape the environmental agenda and reflect its relevance and credibility.
