A seaweed solution
to climate change


Greener Grazing™ is an ambitious, one-of-a-kind project that is making scalable Asparagopsis seaweed farming a reality.

Australis Aquaculture co-founder and CEO Josh Goldman built the company to discover how we can better use the oceans to sustain ourselves and restore the planet. Our team is exploring the next frontier of integrated ocean farming to combat our biggest environmental challenge—climate change.

Ground-breaking research has revealed that ruminant animals fed small amounts of Asparagopsis taxiformis, a type of red seaweed, produce virtually no methane during digestion. But A. taxiformis has never been reproduced or cultivated at scale.

Greener Grazing is leading the effort to close the lifecycle of A. taxiformis and to develop the tools needed to farm it on a global scale. If successful, this initiative could dramatically reduce the climate impact of the world’s two billion cattle—the climate equivalent of taking every car on the planet off the road.
