Beefing up seaweed production to green up beef

Josh Goldman, founder and CEO of barramundi producer Australis Aquaculture, is on a mission to reproduce Asparagopsis, a tropical seaweed that could significantly reduce the climate impact of beef production.

Early last year Goldman launched Greener Grazing to develop the technology to produce this pinkish-red sea plant at commercial scale. If it were added to the livestock feed of the world’s 1.5 billion cows, Goldman says it could dramatically reduce theirs and other ruminant animals’ burping of methane gas, which, according to the United Nations, is responsible for 14.5 percent of the world’s annual greenhouse gas emissions.
