Pessarrodona et al. (2024): Carbon removal and climate change mitigation by seaweed farming: A state of knowledge review

Albert Pessarrodona, Jennifer Howard, Emily Pidgeon, Thomas Wernberg, Karen Filbee-Dexter IN: Science of The Total Environment, 918, 170525,

Here the authors examine the results of over 100 publications to synthesize evidence regarding the CDR capacity of seaweed farms and review the different interventions through which an expansion of seaweed farming may contribute to climate change mitigation. They find that presently, the majority of the carbon fixed by seaweeds is stored in short-term carbon reservoirs (e.g., seaweed products) and that only a minority of the carbon ends up in long-term reservoirs that are likely to fit within existing international accounting frameworks.
