Livestock sector contributes to the increase of global warming through gas released from enteric fermentation and manure management. National estimation still uses a manual calculation. The aim of this study was to estimate the contribution of greenhouse gas (GHG) emission from livestock sector by using ALU tool version 6.0.1, in West Java Province in year 2016 as the case study. The emission were calculated by using Tier-1 and Tier-2 methodologies. Data used were livestock population and emission factors (EF) of CH 4 and N 2 O of any livestock. The results showed that emission from enteric fermentation was 94.754 Gg CH 4 /year or 2,368.850 Gg CO 2 e/year with the highest emission from sheep (50.194 Gg CH 4 /year or 1,254.850 Gg CO 2 /year). While emission of CH 4 from manure was 6,767 Gg CH 4 /year or 169,175 Gg CO2e/year with the highest emission from dairy cattle (2,870 Gg CH4/year or 71,750 Gg CO 2 e/year) and direct N 2 O emission from manure was 0.366 Gg N 2 O/year or 109.138 Gg CO 2 e/year with the highest emission from sheep (0.189 Gg N 2 O/year or 56.212 Gg CO 2 e/year). As a conclusion, total emission from the livestock sector in West Java Province was 2,647.163 Gg CO 2 e/year with the largest emission was from enteric fermentation (2,368.850 Gg CO 2 e/year). This study suggests that ALU tool is applicable to estimate GHG emission for Livestock in Indonesia with limited data available.
