(See Table, next page.) "There are large variations in the energy efficiencies and CO2 reduction efficiencies of biofuels stemming from different raw material sources and manufacturing processes," says Lee Chien-ming, assistant professor at National Taipei University's Institute of Natural Resource Management.
（見各生質燃料生命週期表）「生質燃料的能源效益和 CO2 減量的環保效益，因為料源和製程不同，變異極大，」台北大學自然資源與環境管理研究所助理教授李堅明指出。
