LCA (Life Cycle Assessment) carried out to estimate carbon footprint and to establish of LCI (Life Cycle Inventory) database of rice production system. The results of collecting data for establishing LCI D/B showed that organic fertilizer and chemical fertilizer input to 4.29E-01 kg kg-¹ rice and 2.30E-01 kg kg-¹ rice for rice cultivation. It was the highest value among input for rice cultivation. And direct field emission was 3.23E-02 kg kg-¹ during rice cropping. The results of LCI analysis focussed on greenhouse gas (GHG) was showed that carbon footprint was 8.70E-01 kg CO₂-eq. kg-¹ rice. Especially for 80% of CO₂ in the GHG and 7.02E-01 kg of its CO₂-eq. kg-¹ rice. Of the GHG emission CH₄, and N₂O were estimated to be 13% and 5%, respectively. With LCIA (Life Cycle Impact Assessment) for rice cultivation system, it was observed that fertilizer process might be contributed to approximately 80% of GWP (global warming potential).
