This study was carried out to estimate carbon emission using LCA and to establish LCI database of potato
production system. Potato production system was categorized into the fall season potato and the spring season
potato according to potato cropping type. The results of collecting data for establishing LCI D/B showed that
input of fertilizer for fall season potato production was more than that for spring season potato production.
Input of pesticide for spring season potato production was much more than that for fall season potato
production. The value of field direct emission (CO₂, CH₄, N₂O) were 2.17E-02 kg kg-¹ for spring season potato
and 2.47E-02 kg kg-¹ for fall season potato, respectively. The result of LCI analysis focussed on the
greenhouse gas (GHG), it was observed that carbon footprint values were 8.38E-01 kg CO₂-eq. kg-¹ for spring
season potato and 8.10E-01 kg CO₂-eq. kg-¹ for fall season potato; especially for 90% and 6% of CO₂ emission
from fertilizer and potato production, respectively. N₂O was emitted from the process of N fertilizer
production (76%) and potato production (23%). It was observed that characterization of values of GWP were
8.38E-01 kg CO₂-eq. kg-¹ for spring season potato and 8.10E-01 kg CO₂-eq. kg-¹ for fall season potato.
