This study was conducted to estimate the carbon footprint and to establish the database of the LCI (Life Cycle
Inventory) for barely cultivation system. Barley production system was separated into the naked barley, the
hulled barley and the two-rowed barley according to type of barley species. Based on collecting the data for
operating LCI, it was shown that input of fertilizer was the highest value of 9.52E-01 kg kg-¹ for two-rowed
braley. For LCI analysis focussed on the greenhouse gas (GHG), it was observed that carbon footprint were
1.25E+00 kg CO2-eq. kg-¹ naked braley, 1.09E+00 kg CO2-eq. kg-¹ hulled braley and 1.71E+00 CO2-eq. kg-¹
two-rowed barley; especially two-rowed barley cultivation system had highest emission value as 1.09E+00 kg
CO₂ kg-¹ barley. It might be due to emit from mainly fertilizer production for barley cultivation. Also N2O was
emitted at 7.55E-04 kg N₂O kg-¹ barley as highest value from hulled barley cultivation system because of high
N fertilizer input. The result of life cycle impcat assessment (LCIA), it was observed that most of carbon
emission from barely cultivation system was mainly attributed to fertilizer production and cropping unit.
Characterization value of GWP was 1.25E+00 (naked barley), 1.09E+00 (hulled barley) and 1.71E+00
(two-rowed barely) kg CO₂-eq. kg-¹, respectively.
