A thematic analysis of 18 international biodiversity frameworks to assess the representation of seaweeds. It explores ways to better integrate them into policies. Obstacles preventing full integration include imperfect institutional coordination, inconsistent terminology use, limited representation within biodiversity targets and the absence of legally binding agreements with enforcement mechanisms.

It recommends improvement of seaweed integration into biodiversity frameworks, thereby supporting broader marine ecosystem resilience. This will contribute to achieving Sustainable Development Goal 14 (Life below water).
