IMO Adopts Marine Geoengineering Assessment Frameworks for Ocean Carbon Removal Research

IMO member states have adopted new assessment frameworks for marine geoengineering research under the London Convention and London Protocol. The frameworks cover ocean fertilization, ocean alkalinity enhancement, and ocean sinking of biomass. They require case by case review, environmental assessment, monitoring, and transparent reporting before research can proceed. The decision matters for carbon removal policy because the ocean is increasingly seen as a place to store carbon. It does not yet approve commercial deployment. It sets rules for testing these methods safely, with scientific evidence as the gatekeeper. For anyone tracking carbon markets or climate engineering, this is a signal that ocean-based carbon removal is moving from theory into regulated practice.

Good to see IMO putting a review process around marine geoengineering instead of letting pilot projects run ahead of the science. Ocean alkalinity enhancement and biomass sinking could matter for carbon removal, but the ecological unknowns are large. Case by case assessment with monitoring and peer review is the right starting point. The real question is how long before anyone gets approval to move past research.

The case by case part is the key detail. Without it, the frameworks would just be a moratorium with extra paperwork. What is less clear is how these decisions interact with national carbon credit claims. If a project gets approved for research, does the stored carbon count toward any inventory or market? That gap will matter once commercial proposals show up.

Worth noting these are research frameworks, not deployment rules. That means the hard part is still ahead: proving monitoring actually works at scale. Ocean carbon measurements are noisy, and attribution gets messy fast. I want to see the post project review requirements before judging whether this is rigorous or just bureaucratic.

Agreed on monitoring. The frameworks cover risk management and post project review, but the article does not say what those require. If the review is just a report filed after the fact, it will not catch ecosystem damage in time. The London Protocol has been cautious for years, so this is progress, but the implementation details decide whether it means anything.

One thing missing from the coverage is how this fits with the BBNJ agreement and the broader UN ocean governance picture. They agreed to intersessional work on that relationship, which could end up defining which body has final say on marine geoengineering. For anyone tracking carbon removal policy, that is a thread worth following.
