IDDA focuses on sustainability

According to current estimates, one truckload of plastic waste ends up in the world’s oceans every minute. That’s more than 10 million tons a year! With the SAVEtheOCEAN cards, we – together with you – make a contribution against marine pollution and for environmental protection.


sustainable diving

Sustainability rules are introduced in every course. Each student diver is taught to leave the seas cleaner than they found them.



Our SAVEtheOCEAN cards are made from recycled plastic salvaged from the oceans. We print brevets exclusively on these cards.
