Carbon Dioxide Removal


Ocean and Coastal CDR

Ocean based carbon dioxide removal methods include ocean alkalinization or enhancement, ocean up-welling, and enhanced kelp farming. Coastal blue carbon is the carbon captured by living coastal and marine organisms and stored in coastal ecosystems, such as salt marshes, mangroves, and seagrass beds.
