Some Green Fins members have not been able to go through their annual assessment process due to the pandemic. An inactive status does not mean they are not operational or that they are not following environmental standards. Please contact members directly to see if they are open for business. The Green Fins teams will be doing all they can to reassess members in their respective countries as soon as it is possible and safe to do so.

Green Fins members are dive or snorkel operators who agree to follow the Green Fins Code of Conduct, are based in an active Green Fins location and have signed the membership form. Members receive annual assessments, training and feedback to help them improve their environmental sustainability.

Dive and snorkel centres operating in active Green Fins locations can become members by signing (and sending in) the membership form and pledging to follow the Green Fins Code of Conduct. One of the Green Fins team will then be in touch to organise your first assessment.

An active Green Fins country is a destination whose Government has adopted the programme, and has trained Green Fins assessors who are qualified to recruit, train and conduct assessments of dive and snorkel operators in that country. These are:

Dive and snorkel centres who aren’t in an active Green Fins location can still get involved by 

  • Starting to reduce their environmental impact by visiting the Downloads section of the Green Fins website where all materials are completely free to download and use. Just print them out and start promoting them to dive managers, guides and customers.
  • Encouraging staff to complete the Green Fins Dive Guide e-Course which is free to take (and has the option of making a $25 donation to receive an e-certificate).
  • Signing the membership form and sending it to [email protected] to register your interest in membership. You will then be contacted if Green Fins becomes active in your destination. 
  • Following Green Fins on social media (Facebook, Twitter, Instagram) for the latest updates and news on sustainable diving.

Green Fins membership is free. You will just need to cover the cost of up to 2 assessors for at least 1 diving or snorkelling trip per year.

In some countries, members are asked to cover the operational costs of their assessment; for example, paying for the educational materials and / or covering costs for assessors’ travel and accommodation.

Green Fins Assessors are typically staff from government departments and NGOs within that country. They are independent, experienced divers (or snorkellers) who have passed the 6-day Assessor Training Programme conducted by Reef-World Trainers. All certified Assessors carry a valid Assessor card to demonstrate they have undergone the training and achieved the standard required.

The assessment process is most valuable if you do not change from your normal operations. This allows Assessors to highlight the most practical solutions for the environmental challenges you are facing. The assessment is not a judgement or a test; it is a tool to help you understand how best you can improve. Think of it more as a confidential consultation than an exam.

During your annual assessment, assessors will join a typical diving or snorkelling trip with your guests to observe and interact with your staff, look around the shop and ask a few questions. They need to conduct at least one dive with your staff and guests and are trained to not disrupt your operation, staff or guests’ experience.

Assessors will be looking at how your daily operations, both above and below the water, relate to the Green Fins Code of Conduct and will provide feedback to the management of the operation based on standardised criteria. Together with your local Green Fins Assessor, you will discuss and agree to at least 3 action points to focus on for the next year. As the assessment is repeated annually, you will be able to monitor your progress and demonstrate your improvement.

The assessment is usually completed within one day and includes: 

  • At least 1 dive or snorkel session depending on how your operation runs.
  • A feedback session with management / owner (typically 30 mins).
  • Staff training presentation (45 mins – 1 hr)

Yes. The Green Fins posters are all free to download and can be used by members and non-members alike.

Green Fins is now beginning to be available to companies offering diving and snorkelling liveaboard trips; however, the possibility of this does depend on the logistics of organising an assessment. If you are a liveaboard company operating in an active Green Fins country and are interested in joining Green Fins, please contact [email protected] to discuss your situation.
