ABSTRACT Blue carbon habitats, which exhibit high rates of natural sequestration, typically refer to salt marshes, seagrass meadows, and mangrove forests. Recent studies, however, have argued for the inclusion seaweed‐dominated like kelp forests, into blue frameworks. Farmed seaweed may also function as a habitat, with large‐scale aquaculture suggested climate change mitigation strategy, but evidence base remains limited. Here, existing knowledge on mechanisms influencing uptake, release, transport, storage from farms was synthesised, literature review conducted quantify associated sequestration. We identified strong geographical methodological biases in literature, majority studies Asia focusing primary production proxy sequestration potential. Estimates release were highly variable across locations, species, approaches, scarcity research dissolved organic carbon, sedimentary net ecosystem productivity identified. Although European farming industry is its infancy, it predicted expand meet increasing demand biomass. This incentivised by perceived service benefits such enhanced However, multiple factors including environmental concerns, lack quantitative evidence, operational challenges, regulatory complexities hinder expansion. Based both synthesised empirical an examination key barriers gaps, we identify future challenges priorities needed assess role mitigation.

ABSTRACT There is growing interest in establishing a seaweed farming industry Europe, and this has the potential for being mechanism atmospheric carbon dioxide removal (CDR). The EU recognises of CDR to help meet climate change targets, but also acknowledges importance creating credible markets ecosystem services (ES) through voluntary promote sustainable investment avoid claims greenwashing. In response this, proposed framework (termed QU.A.L.ITY) establishment certification schemes, based on four criteria quantifiable, additionality, long‐term storage overall sustainability. While aquaculture holds could QU.A.L.ITY generic level, specific projects face hurdles data collection, standardized methodologies, sediment protection regulations, applicability taxonomy. Robust frameworks like EU's are crucial greenwashing ensure action CDR.

Abstract Seaweed is a potential source of sustainable food, feed, cosmetics, biomaterials, and biostimulants. currently mainly grown in Asia, it unclear which seaweed systems are best suited for North-West European waters. We use an expert workshop written feedback round to identify prospective systems, including the cultivation site post-harvest stages, three different contexts. Independent context, there preference cultivating multiple species having high level automation. Depending on optimal choice with regards scale, substrate, seeding technique, integration farming (shell)fish differs. Profitability availability (large-scale) processing facilities ships go offshore, uncertainty buyers, obstacles seed stock availability, permits, building infrastructures present key challenges risks. The identified serve as input policy debate around alternative resource production Europe can help developing standards system design. Furthermore, researchers technology providers future profitability assessments directions developments.
