Climate change mitigation requires immediate and long-lasting drastic reductions in anthropogenic greenhouse gas emissions. As some of these emissions cannot easily be avoided, the net-zero emissions aim can only be reached through carbon dioxide removal (CDR) strategies. Many of these rely on technical, physical or chemical approaches that are promising but not yet fully implementable nor fully accepted by society (https://cdrmare.de/en). Nature-based Solutions (NbS), by contrast, may be less efficient but enjoy high societal desirability and methodological feasibility. sea4soCiety aims at developing innovative approaches to enhance the potential for Blue Carbon sequestration in mangrove forests and other blue carbon ecosystems (saltmarshes, seagrass meadows, kelp beds), e.g., through expanding their spatial extent into new areas, if and where ecologically feasible, environmentally sound, legally and ethically unobjectionable, socially acceptable, and economically viable. I will critically shed light on the general concept, progress and first findings specifically with respect to methodology, organic matter stability and origin, faunal effects on carbon fluxes, and societal perception and acceptance.
