The International Maritime Organization has adopted new assessment frameworks for marine geoengineering research under the London Convention and London Protocol. The rules cover ocean fertilization, ocean alkalinity enhancement, and sinking biomass, and require case-by-case review before research can proceed. This gives regulators a clearer way to weigh climate benefits against risks to marine ecosystems. The move comes as interest grows in using the ocean to absorb and store carbon dioxide. For carbon market participants, the guidance matters because it sets early guardrails for ocean-based carbon removal projects that may eventually seek credits. It also clarifies what counts as legitimate scientific research versus commercial activity. Read the full article for details on the IMO resolution and the Irish research context.
