Certification process

Green Marine participants are committed to continually reducing their environmental footprint.

Rigour and transparency

To obtain Green Marine certification, participants must complete all the requirements of the rigorous and transparent certification process.

Annual self-evaluation

For each applicable performance indicator, a participant must evaluate its environmental performance on a 1-to-5 scale using the self-evaluation guide development by Green Marine. The participant must complete the self-evaluation no later than March 15 of each year.

External verification

Every two years, the participant must submit the results to an external verifier accredited by Green Marine. The verification process is done in person on the company’s premises, unless there are extraordinary constraints. It is carried out based on the documentation provided by the participant in support/justification of the self-evaluation. Initial certification is only granted after a participant’s first self-evaluation results are reviewed by an external verifier.

Publication of the results

The individual results of each of the participants are revealed each year at GreenTech – Green Marine’s annual conference. Each participant’s results, as well as certification status, are also published in the performance report on Green Marine’s website under the participant’s profile as well as on the Results page.

Continual improvement

As of the very first year in the program, a participant must achieve Level 2 for at least one of the performance indicators. Thereafter, the participant must demonstrate a yearly improvement of one level for at least one performance indicator until Level 2 is achieved for all the applicable performance indicators.
