The aims of this study are to estimate the GHG emission from livestock in West Java and the trends of the emission from 2006 to 2030 with specific GHG analysis in 2022. The GHG emission was calculated using the Tier 2 method recommended by the Intergovernmental Panel on Climate Change (IPCC) 2019 Refinement. This study used Indonesia local emission factors for each type of livestock (beef cattle, dairy cattle, buffalo, sheep, goat, horse, chicken and pig) and livestock sub-categories (weaning, yearling and adult). The sources of GHG emission calculated in this study were from enteric fermentation ( CH4) and manure management ( CH4, direct N2O and indirect N2O). The official livestock population data from Indonesia Statistics Agency were used as data activity. The result showed that livestock emission from West Java consisted of 2.49 Gg ton CO2−e of CH4 enteric fermentation, 0.22 Gg ton CO2-e of CH4 manure management, 0.18 Gg ton CO2−e of indirect N2O manure management and 0.87 Gg ton CO2−e direct N2O manure management in 2022. The highest contributor of both enteric fermentation and manure management was sheep, followed by beef cattle, chicken, dairy cattle, buffalo, goat and horse which contributed 56%, 13%,13%, 7%, 6%, 4% and 1%, respectively. The trends of emission were increased each year until 2030 in each source of emission and type of livestock. These trends were caused by the increasing demand of livestock products as a source of food which was represented by the high livestock population trends. It can be concluded that efficiency in livestock production and improvement in mitigation actions to lower the emission is required.
