Abstract
Indonesia is ranked 9th as a country contributing 1.6% to total global emissions and is committed to reducing GHG emission targets unconditionally by 29% and conditionally by 41 % compared to the business as is a scenario of 834 Mt CO2e and 1,185 Mt CO2e, respectively, in 2030. Mining industry has been viewed as one of the largest contributors to GHG emission with a specific process that inevitably generates it. Mobile sources produce direct GHGs of CO2, CH4, and N2O. This study is intended to compare the results of the emission intensity and impact of coal mining production activities as the compounded GHG to discern which of them yields the enormous amount of emission. The method is concentrated only on scope 1 and Tier 2 as a direct responsibility of BUMA as a coal mining contractor. The total amount of fuel consumption GHG emissions was 512,193 tCO2e at Binsua and 742,006 tCO2e at Lati. The composition of the highest emission equipment at Binsua and Lati in 2020-2021 is dump trucks, loaders, and dozers. BUMA will continue to develop potential GHG roadmaps and focus on the performance of dump trucks and excavators, as they are responsible for more than 70% of scope 1 emissions.
