ENVIRONMENTAL EVALUATION OF BIOFUELS

Abstract

One of today´s most important environmental issues is the pollution caused by traffic and transport. There is no doubt that engine emissions, particularly from cars and trucks, have been linked with severe damages to the environment and human health. The substitution of conventional fuels (gasoline, diesel) by biofuels is considered to be a potential way to reduce pollution and support sustainable agriculture. The two most common biofuels are biodiesel and ethanol. The use of biofuels is considered to be environmentally friendly. The production of biofuels, however, might cause pollution. Life-cycle assessment is the scientific evaluation method to investigate the net environmental impacts of biofuels. By means of this method it is possible to determine whether the use of biofuels or the use of conventional fuels trigger more pollution to the environment. Biofuel policy might capitalize on the production of biofuels supporting rural economic development and sustainable agriculture.
