Opportunity: Reduce methane emissions released into the atmosphere as a byproduct of cattle digestion. Methane accounts for more than 10% of all US greenhouse gas emissions, and pound for pound, its impact is more than 25 times greater than that of carbon dioxide.

Vision: Dramatically reduce methane emissions from cattle by utilizing a natural feed ingredient made from a unique seaweed. When added in small amounts to cattle feed, this seaweed reduces burped methane emissions by up to 80% without impacting cattle health or the taste and chemical composition of dairy and beef products.
