Given the context-specific variability and uncertainty around input parameter values in Life Cycle Assessment/analysis (LCA), country-specific studies are needed for providing quantitatively more meaningful results (Larson, 2006).The paper performs a review of a large portion of the existing scientific literatures that explicitly used LCA methodology, or a life-cycle approach to estimate the energy and environmental impacts of biofuels.The review is limited to energy balance and Greenhouse Gas (GHG) balance and covers a time period of approximately 10 years from the 2003 as the early press time and 2012 as the latest press time.45 studies were reviewed, considering 9 kinds of feedstocks, corn, wheat, sweet sorghum, cassava, waste oil,soybean, jatropha, corn stover and algae.All the studies were undertaken in Chinese context including papers or books written in both English and Chinese.Fuel product as conventional liquid biofuels (fuel ethanol and biodiesel) and potential future liquid biofuels (Fischer-Tropsch fuels and cellulosic ethanol) are included.It is explicitly that there are wide ranges of LCA values due to various research scope, methodologies, specific cropping system and conversion system chosen.It is suggested that methodological standards for calculating the LCA energy and GHG balance should be proposed by government to reduce the uncertainty and involve enough scientific evidence.The simulation policy mechanisms should be adopted in China to link support to performance on energy and GHG balance.
