Livestock contributes approximately one-third of global anthropogenic methane (CH4) emissions. Quantifying the spatial and temporal variations of these emissions is crucial for climate change mitigation. This study uses the Tier 2 method from the IPCC guidelines to estimate methane emissions from global livestock, finding a fourfold increase over the past 130 years. The growth in global methane emissions mostly occurred after 1950 and was mainly attributed to the cattle sector.
