The Sea Tree is planned as a buoyant structure anchored in the water by a cable. Conceived by Dutch architect Koen Olthuis of the Waterstudio, it comprises multiple tiers intended as habitats for flora and fauna, both above and below the waterline. A Sea Tree donor is a company that has previously backed this initiative.

It was a deliberate choice to filter in the nuances. This means we don’t just include certified accreditation but also unregulated terms and commonly used jargon. We chose to do this in order to gain a more rounded picture of each brand, aiming to enhance the validity and reliability of our understanding of their ethical stance.
