ArkeaBio™, a leading ag-biotech start-up developing a vaccine to reduce livestock methane emissions, announced the close of a $26.5 million Series A financing round. The raise was led by current investor Breakthrough Energy Ventures (BEV), and attracted additional investors, including The Grantham Foundation for the Protection of the Environment, AgriZeroNZ, Rabo Ventures, Overview Capital, and The51 Food & AgTech Fund.

ArkeaBio’s vaccine will provide an innovative, cost-effective, and scalable solution to reduce the world’s livestock methane emissions, which currently generate the equivalent of 3 Billion Tonnes of CO2 annually and represent 6% of annual Greenhouse gas emissions. “Reducing methane emissions from the agricultural sector is one of the most pressing challenges in today’s fight against climate change,” said Chris Rivest, Chairman of the Board at ArkeaBio and partner at Breakthrough Energy Ventures. “ArkeaBio’s approach using innovative vaccine technologies will create effective and massively scalable solutions to reduce on-farm methane emissions, leaving them well-positioned to redefine the agricultural landscape in the years to come.”

ArkeaBio research and development results have garnered substantial attention from investors for the advancement of the inaugural methane-reducing vaccine, designed for safe and rapid implementation within existing on-farm practices. The funds raised in this Series A financing will play a pivotal role in expanding the research, development and deployment of the vaccine, including large-scale field trials and engagement along the supply chain. “We are thankful for the financial support, confidence, and trust of our investors. This funding will accelerate the development of our vaccine-based solution to meet a pressing global problem,” said Colin South, ArkeaBio CEO. “To echo the sentiments of The Grantham Foundation: ‘climate change is the greatest challenge humanity has ever faced. It is the race of our lives.’ This capital raise allows us to continue to create the tools necessary for farmers to achieve globally relevant reductions in livestock methane emissions.”

ArkeaBio is dedicated to collaborative efforts with industry partners, regulatory authorities, and environmental organizations to bring this transformative solution to market.

"Enteric methane emissions are responsible for around 10% of global warming. Enteric methane emissions are also very hard to abate. New technologies can help to prevent accelerating methane emissions from the agricultural sector. We are excited to support ArkeaBio's development of methane vaccines for ruminants on their pathway to commercialization."

“A methane vaccine for ruminant animals is internationally recognised as the ‘holy grail’ to deliver methane reduction at low cost and mass scale. It could be one of the best long-term options to really shift the dial on agricultural emissions and a powerful tool globally. We’re really pleased to be supporting ArkeaBio and its innovative approach to develop this important solution.”

‘'As a cooperative bank, we want to future-proof our global food system by supporting and offering solutions that have the potential to reduce the environmental impact of agriculture. In our search for solutions that can lower the footprint of livestock farming and be applicable across all feeding systems, ArkeaBio emerged as a game-changing solution. Their cost-effective, easy-to-deploy and high-quality vaccines have the potential to be a critical tool as part of the broader set of solutions that enable the food systems transition.''
