ArkeaBio
A pioneer in developing technology to reduce greenhouse gas (GHG) emissions from the agricultural sector
Our Mission
ArkeaBio is using innovative vaccine technologies to create solutions to reduce the on-farm methane emissions responsible for 6% of global GHG emissions. ArkeaBio technology will be integrated into proven delivery systems and farming practices to safely reduce global methane emissions from multiple ruminant species across a variety of geographies and agronomic systems.
Our Vision
Our vision is to eliminate the on-farm methane emissions from ruminant animals (including cattle sheep and goats) that are responsible for 6% of global greenhouse gas emissions.
