How necessary and feasible are reductions of methane emissions from livestock to support stringent temperature goals?

ABSTRACT: Agriculture is the largest single source of global anthropogenic methane (CH₄) emissions, with ruminants the dominant contributor. Livestock CH₄ emissions are projected to grow another 30% by 2050 under current policies, yet few countries have set targets or are implementing policies to reduce emissions in absolute terms. The reason for this limited ambition may be linked not only to the underpinning role of livestock for nutrition and livelihoods in many countries but also diverging perspectives on the importance of mitigating these emissions, given the short atmospheric lifetime of CH₄. Here, we show that in mitigation pathways that limit warming to 1.5°C, which include cost-effective reductions from all emission sources, the contribution of future livest
