Kelp is also commonly referred to as seaweed and refers to a group of brown algae comprising 34 genera and 129 different species. Kelp can store about six times as much_CO2as trees, which is why it is of particular interest to us. Unfortunately, it is not yet possible to build a property that is completely_CO2-free, at least not if it is to be affordable. We offset the excess_CO2—which cannot be neutralized either through the careful selection of building materials or through timber construction—by financially supporting an innovative project.
We support SeaForester, a company dedicated to the reforestation of dead kelp forests in the oceans. Kelp not only sequesters_CO2but also improves water quality, reduces acidification, and enriches the water with oxygen. Furthermore, it slows down wave action on exposed coasts, thereby preventing erosion and providing a habitat for many marine animals, which find shelter from predators here and often use the kelp forests as nurseries. Cultivating kelp is therefore not only a measure for climate protection but also promotes biodiversity and water quality in our oceans.

SeaForester has developed Green Gravel, a new method for reforesting kelp forests over large areas in a cost-effective manner. Young kelp plants (zygotes) are cultivated on pebbles at a breeding station. These can then be easily deployed from a boat in suitable coastal regions without the need for divers. The roots of the small plants then grow beyond the pebbles and anchor themselves in the seabed, from where they grow toward the surface. Due to the very rapid growth of many kelp species, this method allows large coastal areas to be reforested in a short period of time.
