The environmental potential impacts of rice husk fast pyrolysis and upgrading in supercritical ethanol (PY-USE) system and catalytic hydrotreating system (PY-CH) were calculated and compared based on the life cycle assessment (LCA) models. The results of this work revealed that FDP, GWP, ODP, POCP and AP of the PY-CH system were lower than those of the PY-USE system, while the HTP and EP was higher than that of PY-USE system. The fossil ethanol consumed during fast pyrolysis and upgrading process and agriculture system were the main sources of the potential environmental impacts of the PY-USE and PY-CH system, respectively. It was founded that the impact of the pyrolysis fuels were lower than that of the fossil fuels for FDP, GWP and ODP, but higher for HTP, POCP, AP and EP. LCA results showed that greenhouse gas(GHG) saving of 38.83% and 45.93% for the produced fuel of PY-USE system compared to conventional gasoline and diesel, while the GHG saving of 73.50% and 76.58% for the fuel of PY-CH system.
