Kappaphycus and Eucheuma red seaweeds are closely related genetically are currently the most widely and largely produced by volume compared to other varieties (Hurtado.) The development of seaweed aquaculture is a viable source for carbon offsetting in the oceans. Other forms of aquaculture (fin-fish and crustaceans) produce a large proportion of the emissions in aquaculture, around 300 thousand tonnes of CO2 per year. Seaweed aquaculture produces around 1.1 thousand tonnes per year per every square kilometer. Based on this data, we can calculate it would take a comparatively small area to make the industry carbon-neutral when compared to the other forms of aquaculture. Agriculture produces around 12% of the global emissions annual and has for the past thirty years, totaling around 5.1 billion tonnes of CO2.
