Sinking seaweed in the deep ocean for carbon neutrality is ahead of science and beyond the ethics

Sinking vast amounts of seaweed in the deep ocean is currently being proposed as a promising ocean carbon dioxide removal strategy as well as a natural-based solution to mitigate climate change. Still, marketable carbon offsets through large-scale seaweed sinking in the deep ocean lack documentation and could involve unintended environmental and social consequences. Managing the risks requires a number of urgent actions.

Sinking large amounts of seaweed in the deep ocean is proposed as a promising strategy for removing carbon dioxide and mitigating climate change, but the lack of documentation for marketable carbon offsets through this method may lead to unintended environmental and social consequences. Urgent actions are needed to manage these risks.
