For generations, seaweed has remained one of the great untapped resources. But a revolution is coming.
The Global Seaweed Coalition is a global partnership established by Lloyd’s Register Foundation in partnership with the UN Global Compact (UNGC) and the Centre National de la Recherche Scientifique (CNRS) to oversee the safety and sustainability of the seaweed sector as it scales up.
Dollars
Size
In the 10 years to 2015, the annual value of the seaweed market doubled in size.
Times
Our oceans have the potential to produce 15 times more seaweed by 2050.
People
This growth could provide employment for 150 million people around the world.
The world’s fastest growing food production sector
Seaweed is the world’s fastest growing food production sector, with a current annual value of $9bn. In the 10 years to 2015, it doubled in size as the world started to recognise the role seaweed can play in securing food systems for an expanding global population.
This is just the start: our oceans have the potential to produce 15 times more seaweed by 2050, securing employment for millions of people in every continent, absorbing carbon to help fight the climate crisis and providing essential nutrition to meet the needs of the world’s growing population.
But with growth come challenges.
Our objectives
Consumer safety
Defining commonly agreed safety standards for seaweed products used by consumers
ENVIRONMENTAL SAFETY
Ensuring scaled-up production and processing of seaweed is sustainable and restores ecosystems.
OPERATIONAL SAFETY
Ensuring the welfare of workers is protected at every stage of the seaweed value chain
