Use of bio-ethanol and bio-diesel the key solution for a more sustainable road transport

Life Cycle Analysis (LCA) of alternative transportation fuels clearly shows the advantages of reducing the use of non renewable fossil fuels vs. renewable biologic novel fuels to reduce the emissions of carbon dioxide. Being based on the natural recycle of carbon dioxide through the use of renewable energy sources, use of these renewable fuels do not imply depletion of natural resources and is therefore sustainable in the long term. Renewable fuels and advanced internal combustion engines and powertrains are the technologies that in addition to be the most likely to produce benefits in term of carbon balance and fossil fuel saving, are also those that unequivocally have the smallest ecological footprint considering all the environmental implication of transportation technologies, with all the other more exotic solutions having much higher environmental costs to produce, use and dispose of alternative transportation technologies. The use of bio ethanol and bio diesel from non food feed stocks in advanced internal combustion engines and power trains may cut the fossil fuel usage as well as the carbon dioxide emissions by more than 90%.
