Global warming is a problem that impacts in many various sectors include construction. Emission of carbon dioxide (CO2), one of causes of global warming, can be emitted from construction projects. The alternative method that able to calculate CO2 emissions is Life Cycle Assessment approach. The purpose of this study is to predict CO2 emission from all beam types using network flow diagram of Life Cycle Assessment in real estate project of 216 m2 type house. The analysis calculated by SimaPro 9.0 software. The results of this research indicated that from four types of beams used in real estate, beam-type 25/50 and beam-type 15/30 have the largest percentage of CO2 emission in 41.9% (4,610 kg CO2-eq) and 39.9% (4,380 kg CO2-eq) of the total CO2 emission of all beam types, respectively. A conventional method of beam construction resulted CO2-eq emission that come from rebar of 31.20% (3.426 kg CO2-eq) and cement 1.09% (120 kg CO2-eq). For the ready mix method, the largest CO2-eq emission are dominated by ready mix at 20.20% (2,200 kg CO2-eq) and wooden blocks 46.90% (5,150 kg CO2-eq).
