ArkeaBio develops a safe, cost-effective vaccine to reduce methane emissions from cattle for farmers and producers worldwide.
ArkeaBio is targeting enteric methane from cattle and other ruminants, a major agricultural climate problem, with a vaccine the company says could reach pasture-based animals that daily feed additives cannot. Its disclosed financing is funding research, farmer pilots and field trials aimed at turning proof of concept into a scalable product, with first revenue reported as a possibility around 2028.
