Charlottenburg-Wilmersdorf: award for innovative climate protection project!

Volkspark Jungfernheide, Berlin, Deutschland - On June 3, 2025, the Charlottenburg-Wilmersdorf district office was awarded the title "Climate protection partner of 2025" by the IHK Berlin. The reason for this honor is the innovative project "Plant Cubal as CO₂ sinks and sponge-a field test in the Volkspark Jungfernheide", which was realized from 2021 to 2023 in the green spaces department. The aim was to renovate the central meadow in the Volkspark on an area of ​​about three hectares. This area plays an important role as a cold air shit for the surrounding residential areas Siemensstadt and Paul-Hertz-Siedlung.

The function of the meadow has been severely affected in recent years by intensive use, drought and the effects of climate change. The use of plant cubes, which permanently binds about 70 tons of CO₂ in the soil, the water storage capacity of the lawn has been significantly improved. The 22 tons brought in the plant that has been brought in has the ability to absorb water until five times their own weight and to release it again if necessary. This leads to a higher resistance to dryness and extreme weather events.

diversity and sustainability promote

It is particularly noteworthy that the planted cubes have been enriched with mycorrhizal mushrooms. These promote the nutrient and water exchange between the soil and the plants. In addition, domestic grasses and herbs made of regiosaatgut were used, which do without artificial irrigation and fertilization, as well as well adapted to the specific conditions in Berlin.

The development of a multi -stage, sustainable sponge concept has so far no parallels of this size in Germany. The biochar not only improves the water balance of the central meadow, but also enables the storage of heavy rain events, which can then seep or evaporate. Each tonal plant can save about 3.2 tons of CO₂, and overall this leads to a permanent fixation of around 70 tons of CO₂ in the soil.

broad effect and scientific support

The project has sparked interest nationwide and internationally. Experts from Europe are now visiting the Volkspark Jungfernheide to convince themselves of the results. The project is scientifically accompanied by the Free University of Berlin. District City Councilor Oliver Schruoffeneger emphasizes the innovative character of the project and the role model function for other municipalities. In addition, the district office plans to extend the method to further parks and checks its own plant cubes.

The use of plant cubes in urban floors is not only crucial for the improvement of water reserves. The geo -ecologist Dr. Nikolas Hagemann emphasizes that plant cubes offer a promising potential for solving climate and environmental problems. Historically, their applications are diverse and extend from agriculture to animal husbandry to new developments in the construction industry.

Overall, the project in the Volkspark Jungfernheide shows how the combination of innovative sustainable practices and scientific support can help make urban habitats more resilient while the climate goals are achieved at the same time.
