What is Oceans 2050?

Seaweed farming is a critical tool for fueling our lives with limited impact on the health of the planet. That's why WWF is partnering with Oceans 2050, a nonprofit organization co-founded by Alexandra Cousteau aiming to restore and protect our oceans, to aid and encourage the growth of the seaweed industry. WWF is advancing the science around the relationship between carbon and seaweed farms and lifting up stories about people and communities that benefit from seaweed farming.

Why is WWF supportive of seaweed farming?

  • Produces nutritious food with no arable land, freshwater, or fertilizer.
  • Absorbs excess nutrients, like nitrogen and phosphorous, that we have too much of in our oceans and reduces ocean acidity.
  • May improve overall animal health when added to livestock feed.
  • Can create less carbon-intensive plastics and protein extracts compared to traditional sources.
  • As fishing stocks are challenged, coastal and Indigenous communities may benefit from scaling up seaweed farming, providing income alternatives with sustainable jobs.

Advancing the science around the relationship between carbon and seaweed farms


Study: Carbon Burial in Sediments below Seaweed Farms
The study seeks to quantify carbon sequestration by seaweed among a global network of leading seaweed scientists and seaweed farm operators who are sampling sediments, advancing the science, and ultimately considering market incentives for seaweed aquaculture as a solution to helping address the climate crisis while contributing to ocean restoration.
