Life cycle assessment of environmental and economic benefits of bio-ethanol in Taiwan

To evaluate the benefits of Taiwan's bio-ethanol crop cultivation promotion on the environment, energy efficiency and economy, we undertake a recording of cultivation resources inputs data in 2007 and 2008 of four energy crops based on the LCA method. We find the net energy balance signifies energy conversion efficiency. As to the GHG, using sugarcane ethanol to replace gasoline could decrease 1.25 kg CO(2)e/litre. This paper will look at various aspects of overseas biofuel efforts, policy and strategies, together with Taiwan's biofuel policy, and analyse energy balance, GHG and production costs as references for Taiwan's national biofuel industry policy.
