Kelp is also known colloquially as seaweed and refers to a group of brown algae comprising 34 genera with 129 different species. Kelp can store around six times as much_CO2 as trees and is therefore of particular interest to us. Unfortunately, it is not yet possible to build a property completely_CO2-free, at least not if it is to be affordable. We bind the excess_CO2 that cannot be neutralized either by the careful selection of building materials or by 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 binds_CO2 but also improves the quality of the water, reduces acidification and enriches it with oxygen. It also slows down the waves on exposed coasts, preventing erosion and providing a habitat for many marine animals, which find protection from predators and often use the algae forests as a nursery. The cultivation of kelp is therefore not only a measure for climate protection, but also promotes the biodiversity and water quality of our oceans.

With Green Gravel, SeaForester has developed a new method of reforesting kelp forests on a large scale and cost-effectively. Young kelp plants (zygotes) are planted on pebbles in a breeding station. These can then be conveniently deployed from a boat to the appropriate coastal regions without the need for divers. The roots of the small plants then grow beyond the pebbles and anchor themselves in the ground from where they grow towards the surface. Due to the very rapid growth of many kelp species, large sections of coastline can be reforested in a short time using this method.
