These data includes outputs on global warming potential (GWP, carbon impact, kg carbon dioxide equivalent) and marine eutrophication potential (MEP, nitrogen impact, kg nitrogen equivalent). Values for the mussel are given per 1 kg live weight. Values for seaweed are given per 1 million tonnes of wet-weight. These data were collected to understand the role that seaweed and bivalve aquaculture can play in achieving Net Zero and eutrophication remediation in England. The life cycle impact assessments (LCIAs) consider rope grown blue mussels (*Mytilus edulis*) and sugar kelp (*Saccharina latissima*) in English waters. Mussels are grown for food purposes, while seaweed is grown for production of biochar and biofuel. The data are given as summaries per component of the life cycle impact assessment as csvs, and the models themselves are exported to text files which can be used in SimaPro.

Inputs used the ecoinvent 3.0 database. The life cycle inventories (LCIs) were compiled using a combination of published peer-reviewed literature and grey literature. For the life cycle impact assessment (LCIA) method, ReCiPe 2016 Midpoint (H) V1.08 was chosen, which is the default ReCiPe midpoint method. MEDIN 3.1.1
