Intensitas emisi GRK dari kegiatan produksi migas cenderung meningkat. Penelitianbertujuan untuk menganalisis emisi GRK, menganalisis biaya pengurangan emisi,menganalisis perilaku KKKS migas serta menyusun mitigasi emisi pada kegiatanproduksi migas. Perhitungan emisi menggunakan metoda IPCC Tier-1, perilaku KKKSdianalisis dari Laporan Keberlanjutan, analisis biaya pengurangan emisi menggunakanmetoda marginal abatement cost (MAC), dan mitigasi emisi disusun berdasarkan KurvaMAC. Hasil penelitian menunjukkan emisi dari sumber pembakaran bahan bakar sebesar354.487 ton CO2e/tahun, sedangkan emisi dari sumber fugitive sebesar 125.476 tonCO2e/tahun. Sumber emisi GRK terutama berasal dari pembakaran pada turbinpembangkit listrik dan kompresor gas. Perilaku KKKS termasuk kategori cukup baiktetapi perlu peningkatan pada perilaku penggunaan energi terbarukan. Beberapa pilihanmitigasi bernilai MAC negatif sehingga berpotensi memberikan keuntungan ekonomibagi KKKS. Mitigasi emisi disusun melalui peningkatan perilaku KKKS dan pemilihanaksi mitigasi yang memberikan penurunan emisi GRK terbesar dengan biayapengurangan emisi terkecil.

The GHG intensity from O&G production activity is continue increasing. This research

aims to analyze the GHG emission, the emission reduction cost, the mitigation behavior

of O&G company, and to develop emission mitigation. The GHG emission is calculated

by IPCC Tier-1 method, company behavior is analyzed thru Sustainability Report, the emission reduction cost is analyzed by marginal abatement cost (MAC), and emission mitigation is developed by MAC Curve. The results showed that emissions from fuel combustion were 354,487 tons CO2e/year, while emissions from fugitive were 125,476 tons CO2e/year. The source of GHG emissions mainly from fuel combustion in power generator equipment and gas compressor. The O&G company behavior is categorized as quite good but need improvement in using renewable energy. Several mitigation options

have found economically beneficial. Emission mitigation is developed thru increasing mitigation behaviour and de
