the keeling POSIDONIA OCEANICA collection project

For Spring Summer 2026, KEELING presents The Posidonia Oceanica Collection — a poetic celebration of nature’s hidden beauty, a sensory journey through the ocean depths and the crystal-clear transparency of the sea. Each piece in the collection reflects the silent elegance beneath the surface: a fluid movement among seagrass blades, a dance of light filtered by the water, a whisper of life thriving in the depths.

Light, flowing lines and sophisticated natural textures evoke the delicacy of waves and the softness of the seabed. The choice of materials is central to this story: linen and cotton, fresh and breathable like a sea breeze, combined with a polyamide designed to reduce environmental impact and prevent the release of microplastic particles into the oceans.

A KEELING garment is more than just clothing: it is a conscious choice, a small yet meaningful step towards protecting our blue planet. With every purchase, KEELING supports B Corp certified projects dedicated to the protection and restoration of Posidonia Oceanica meadows — vital ecosystems for the health of the Mediterranean.

why the POSIDONIA OCEANICA?

We are not the only one who claim this: FAO says it clearly. Marine environments are a very important source of energy, food, and jobs for millions of people, but marine resources are often overexploited or disregarded.

In the Mediterranean, the surface water temperature recently reached an all-time high of +31°C, and in some areas the concentration of microplastics approaches 10 kg per square kilometer. Posidonia oceanica is a plant species exclusive to the Mediterranean, and in the last 50 years 29% of its seagrass beds have regressed because of excessive human activities and their impact on the marine ecosystem. More Posidonia in the sea means up to 14 liters of oxygen released every day through photosynthesis for each square meter of seagrass. It also means more biodiversity in the marine ecosystem, a brake on coastal and littoral erosion, a positive impact on the local economies, and a concrete commitment against climate change.

Meadows to mitigate the Waves

Posidonia roots form dense taproots that weave through the marine sediment, stabilizing the seabed. The density of the plants and their stems slows the movement of the waves, absorbing some of their energy.

This reduces the impact of waves on the coast, preventing sand loss and beach degradation. In addition to protecting biodiversity, Posidonia plants make an important contribution to protecting beaches and coasts from erosion, thanks to their roots and long ribbon-shaped leaves that mitigate wave action. Fallen Posidonia leaves and organic plant debris help form a layer of sediment on the seabed. These sediments act as a natural deposit of sand and materials, which help in the maintenance and restoration of eroded beaches.

Oxygen for the marine ecosystem.

Posidonia meadows are among the most efficient producers of oxygen in marine ecosystems. It is estimated that a Posidonia seagrass meadow can produce up to 14 liters of oxygen per square meter per day.

Posidonia meadows are primary habitats in the Mediterranean and are home to about 25% of the marine species in this sea. Posidonia is not a seaweed, but a true plant with ribbon-like leaves that can grow up to 1 meter long, capture carbon dioxide, and release oxygen. One hectare of seagrass can host up to 350 different species, residents or migrants, providing shelter and food for crustaceans, fish, and numerous other marine species of great environmental and economic importance.

From cuttings to grasslands.

Our work begins by mapping the seabed and conducting a survey with specialized divers to verify that the selected area and its substrate are suitable for reforestation.

Reforestation is already a very complex activity on land, let alone at 10 meters below the water surface! Here are all the steps we follow to repopulate a meadow of Posidonia oceanica in the Mediterranean:

1. We choose a suitable area for the transplantation
2. We collect cuttings in the open sea*
3. We place sustainable mats on the seabed
4. We plant the cuttings on the mats
5. We take care of it over time

The B Corp Certified project

Is a certified B Corp benefit company that develops natural solutions to address climate change, protect ecosystems, and support underprivileged communities. They reforest where there is a real need and support rural families to envision a more dignified future; a future where they don’t have to fight against the expropriation of their own land and where they can apply easy and functional solutions to mitigate the climate crisis.

ZEROCO2 believes in a responsible and equitable future for humans and the environment, with no prevarication of the strongest against the weakest. That’s why ZEROCO2 works to recreate stable ecosystems in harmony with the plants, animals, and the people who inhabit them. ZEROCO2 helps reframing sustainability goals by actively working for the future of the planet. This is not just their goal: it concerns each and every one of us.
