This project, conducted in collaboration with the Australian Sustainable Seaweed Alliance (ASSA) and FRDC, assessed the potential of seaweed aquaculture to generate environmental credits, namely carbon, nutrients (nitrogen and phosphorus) and biodiversity. By conducting a comprehensive review of the literature, the research evaluated the capacity of farmed seaweed to sequester carbon, assimilate nutrients and enhance biodiversity. It assessed the different pathways through which environmental credits could be generated and also highlighted the barriers preventing meaningful participation of the seaweed industry in existing environmental credit schemes. Alongside the review, a consultation was conducted with Australian and international industry members to provide insights into the sector’s positioning and readiness to engage with environmental credit markets. The findings underscored the significant environmental, social, and economic benefits that seaweed farming can offer within emerging environmental markets. The project’s primary output was a policy position for ASSA, offering clear recommendations to government on how the Australian seaweed industry could be integrated into   environmental credit schemes to maximise its potential contributions.
