## About

Founded in 2022 and based in Massachusetts, US, Arkea Bio Corp. operates as a research and development company in the fields of climate change, greenhouse gases, greenhouse gas reduction, greenhouse gas mitigation, and the prevention and inhibition of methane and greenhouse gas production. As of 2022, Colin South is the CEO of the company. In September 2026, Arkea Bio Corp. raised USD 15 million in series A funding led by AgriZeroNZ, with participation from Breakthrough Energy Ventures. The company uses vaccination technology to develop solutions to minimise on-farm methane emissions, which contribute to global GHG emissions. The firm's technology can be linked into proven delivery systems and farming techniques to safely reduce global methane emissions from a wide range of different species across geographies and agronomic systems. The company plans to use the September 2026 funding to advance the development of its livestock methane vaccine, support regulatory approval in New Zealand, and prepare for commercial launch by 2028.
