Discussion highlights the effectiveness of marine carbon dioxide removal, suggesting governance frameworks for carbon credits and scalability.
Navigating the sea of uncertainty around Marine Carbon Dioxide Removal (MCDR) Prof. Christopher Pearce and Dr Willem van Dorp discuss the need for science-based governance approaches when evaluating the potential benefits, impacts and effectiveness of emerging marine carbon dioxide removal techniques. A range of new techniques are currently being explored that seek to extract and permanently store atmospheric carbon dioxide (CO2) in the ocean. The anticipated scalability of these approaches has driven rapid growth in the still-emerging sector, with the first independently verified marine carbon credits being sold earlier this year.
