Charting a Path to Cut the Largest Source of Methane from Human Activity

Who this is For
At a Glance
Why it Matters

It’s time to unlock faster solutions for the largest source of methane from human activity: livestock. Livestock produce more methane than oil and gas production and transportation, coal mining, or landfills and waste management. But unlike those other sectors, we currently lack widely deployable technical solutions to deal with most methane emissions from livestock. 

The key gap is in solutions for enteric methane, which is the methane produced from the unique digestive process of ruminant livestock, such as cattle, and which accounts for about 10% of all greenhouse gas emissions globally. Not having widespread solutions for enteric methane is a problem. But it also presents an important opportunity. Because livestock emissions are so large and because methane is so potent, developing scalable solutions to this challenge would have a significant impact on reducing global warming. Cutting methane also provides cleaner air and saves lives, since methane is a major source of ground-level ozone, a harmful air pollutant responsible for around 500,000 premature deaths annually.

The good news is that promising solutions—such as feed additives, genetic selection, and vaccines—are starting to emerge and mature, while early-stage research on frontier solutions holds additional promise. But despite its importance, livestock methane mitigation has, to date, received only about 2% of agricultural climate research and development funding. To capitalize on these emerging innovations, the sector needs more catalytic funding for research, development, and scaling. 

So what’s holding back more investment? A key barrier is the complexity of the innovation landscape. It requires a lot of expertise to know which solutions can deliver the biggest benefits, in which production systems, on what timeline, and in ways that are both cost-effective and socially acceptable to achieve widespread adoption. A second challenge is understanding what’s holding each potential solution back—from technical hurdles to regulatory barriers to market challenges—and identifying the targeted actions needed to unlock faster progress.

That’s why we developed the Enteric Methane Mitigation Roadmap. It’s a strategic guide designed to make the innovation landscape easier to navigate. The roadmap examines the current pipeline of methane mitigation solutions and evaluates each approach against a clear set of criteria: mitigation potential, safety, cost, social acceptance, productivity impacts, development timeline, and suitability for pasture-based systems. The last factor is particularly important because 90% of the world’s cattle—particularly in developing countries—feed in open pastures where delivering methane-reducing innovations is more challenging than in the intensive systems common in the US. The roadmap also highlights where more research, investment, and coordination are needed most.

This roadmap aims to provide funders and investors with a clearer picture of where and how catalytic commercial and philanthropic investment can support promising innovations and unlock methane-reducing solutions on a global scale to help support expanded and strategic funding for the field. 

This is an outstanding resource—comprehensive, well-structured, and scientifically grounded. It captures both the complexity of the challenge and the pathways toward impactful, scalable solutions. It will be invaluable for guiding research, policy, and investment in enteric methane mitigation. ~ Dr. Karen Beauchemin, Enteric Methane Accelerator Science Oversight Committee, Global Methane Hub

By shining a light on the most promising solutions, the barriers they face, and the actions that could accelerate their progress, we aim to help this critical field move faster and achieve more. With more strategic investments in research and market development, we can help unlock significant progress on a key driver of global warming.
