In 2022, the EU Algae Initiative communication announced 23 actions to support the growth of a sustainable, resilient European algae industry. A handful of actions, including Action 8, aim to work with the algae industry and Member States to consider the development of monitoring methodologies and indicators to measure the environmental impact and sustainability of seaweed cultivation. This study addresses knowledge gaps and develops recommendations for a monitoring framework, targets, and methodologies for quantifying algae’s bioremediation ecosystem-service potential regarding carbon, phosphorus, and nitrogen uptake.
