Natural CO2 reduction implemented faster and with less risk than high-tech approaches

Carbon dioxide can be removed from the atmosphere by natural or technical means. Natural sinks such as peatlands can be restored, and innovative technologies already exist to extract carbon from the air. Researchers from the Helmholtz Climate Initiative's Net Zero 2050 Cluster have identified the approaches with the highest potential for carbon removal in Germany.

Carbon-Hotspots in the Baltic Sea

Marine plants such as seagrass meadows, mangrove forests and salt marshes sequester large amounts of carbon in the sea floor. In the German Baltic Sea, for example, seagrass meadows currently store around 3 to 12 megatons. This is significantly more than was previously known, as the first results from Dr. Angela Stevenson from GEOMAR Helmholtz Center for Ocean Research Kiel show.
