Methane emissions from livestock in East Asia during 1961−2019

East Asia is a crucial region in the global methane (CH4) budget, with significant contributions from the livestock sector. However, the long-term trend and spatial pattern of CH4 emissions from livestock in this region have not been fully assessed. Here, we estimate CH4 emissions from 10 categories...
