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...

| description | 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 of livestock in East Asia during 1961−2019 following the Tier 2 approaches suggested by IPCC (2019). Our results show that livestock-sourced CH4 emission in 2019 was 13.22 [11.42−15.01] (mean [minimum−maximum of 95% confidence interval] Tg CH4 yr-1, accounting for an increase of 231% since 1961. From 1961 to 2019, the emissions increased first and then stabilized after 2000. The contribution of slaughtered livestock to total emissions increased from 3% in 1961 to 24% in 2019 as a result of a significant increase in the slaughtered population. Spatially, the emission hotspots were mostly distributed in eastern China, South Korea, and parts of Japan, but they tend to shift northward after 2000. This latest long-term inventory can help to understand CH4 budget and to assess CH4 mitigation potential at national and regional levels. |
