Green house gases emission of livestock sector in East Kalimantan using Tier-1 2019 refinement

Abstract

The livestock sector is a significant contribution to Greenhouse Gas Emissions (GHG) emissions, especially methane CH4 and nitrous oxide N2O. Each livestock species has a specific characteristic of emission. This research aims to determine the contribution of the livestock sector to GHG emissions in 2019 in East Kalimantan and to predict GHG from this sector over the next ten years. This research estimates the amount of GHG emitted by the livestock sector using formulas and constant values from the IPCC method Tier-1 2019 Refinement. The GHG emission is calculated for each gas based on the population of each species obtained from the East Kalimantan Statistical Center. The projection of GHG is calculated based on the population growth for each livestock species. The result shows the highest emission is contributed by Kutai Kartanegara Regency, 24 % and Beef Cattle 155.14 Gg CO2e or 79%. The projection shows GHG emissions increasing to 340,4 Gg CO2-e in 2030, assuming no significant mitigation effort was conducted.
