Blue Forests – A Review of Carbon Offset Strategies with Seaweed Aquaculture – Feasibility, Current Knowledge, and Suggestions for Future Research

In September 2022, a group of international collaborators gathered from six European countries (hereby referred to as the ‘working group’) to take part in a workshop at the Scottish Association for Marine Science (SAMS), Oban. The workshop was funded as part of Marine Scotland’s Blue Carbon International Policy Challenge (BCIPC). The main aim of the workshop was to produce a document outlining the potential for carbon offset by macroalgal aquaculture. The discussions held at the workshop focused on various concepts and hypotheses surrounding carbon drawdown by seaweed aquaculture and the potential for mitigation of atmospheric CO2. The key points of these discussions have been compiled into a policy brief which aims to highlight important areas for future research, uncertainties and challenges faced by the industry, policy makers and other stakeholders.
