largest Underwater cleanup of the world


In September 2022, two world records were set. The largest underwater cleanup in 12 hours now resides in Sesimbra. This achievement was only possible due to the impressive work of the diving centers Haliotis, Cipreia, Nautilus-Sub, MegaDive, Anthia Dive Center, Arrábida Experiences, Odisseia Azul, Nature Dive, and Wind Team. Their work, combined with an avalanche of divers and nearly a hundred volunteers, allowed for the collection of 3500 kg of trash, the release of several species that were trapped in this trash, and, above all, the passing of a message of unity for the oceans.


On May 27, the World's Largest Underwater Cleanup returns, this time in 24 hours, with the support of the Municipality of Sesimbra. EDP has once again joined this initiative, which aims to bring everyone together for the protection of the oceans, as the main sponsor. International diving organizations SSI and PADI will provide support, as well as the Ocean Azul Foundation, Project Aware Foundation, Ocean Born Foundation, and Blue Oceans. You can find all the event's partners below.


Together, we can change the world. Join us in the second edition of the World's Largest Underwater Cleanup and be part of the change!
