Can Seaweed Cultivation be Used in a Just Transition to Net-Zero?

The rising global temperature is detrimentally impacting Earth’s ecosystem. This research sets out to understand if cultivating seaweed can lead us to Net-Zero, in a just manner. Seaweed absorbs carbon through the process of photosynthesis; increasing the volume of cultivated seaweed in turn, increases the level of carbon dioxide absorbed. This research found that carbon sequestration is not the only benefit of seaweed; seaweed biomass can be used as a biofuel, reducing the need for fossil fuels; and seaweed can be introduced to cattle feed to reduce their methane production. The future of seaweed cultivation is dependent on further research, diversifying farmed species, global integration with equitable opportunities for all, development in technologies, investment and a change to legislation.
