625.64 tCO₂e removal by Planetary

Marine carbon dioxide removal (mCDR) leverages the ocean's natural capacity to absorb and store carbon for thousands of years. These pathways use the biogeochemical and physical properties of the ocean and other bodies of water to capture carbon dioxide from the atmosphere or to permanently store carbon already contained within them. Approaches to mCDR include Ocean Alkalinity Enhancement and Direct Ocean Capture and Storage.
