Abstract
Napier grass is an energy crop for fuel from clean energy resource. Ministry of Energy has target of using Napier grass for electricity generation that was bring to decrease greenhouse gas emissions which cause the global warming. This research is assessed the carbon footprint of Napier grass Pak Chong1. Life cycle assessment was applied in this study from land preparing, seed cane preparing, farming and harvesting. The study area was 105 rai at Dong Prakham district, Phrom Phiram, Phitsanulok. The results showed that the Napier grass farming process has carbon dioxide emission 37.62 kgCO2eq/ yield (ton) or 0.04 kgCO2eq/kg. The farming has the highest carbon dioxide emission 20.07 kgCO2eq/ yield (ton), while harvesting, land preparing seed cane and preparing are 9.98 kgCO2eq/ yield (ton), 4.02 kgCO2eq/yield (ton)  and 3.55 kgCO2eq/ yield (ton), respectively. Net energy consumption is 202.66 MJ/yield (ton). The harvesting highest energy consumption 119.30 MJ/yield (ton) and the land preparing seed cane lowest energy consumption 22.14 MJ/yield (ton).
