Blue Growth Potential to Mitigate Climate Change through Seaweed Offsetting
Carbon offsetting is a contentious but growing market for mitigating climate change. Aquatic farming of seaweeds is a growing sector that may provide a new form of offsetting in the oceans. Froehlich et al. find large-scale global mitigation through CO2eq sequestration unlikely but local to regional applications more feasible.
