It is a well known fact that climate change is one of the most urging problems nowadays. There is evidence that most of the observed global warming is attributable to human activities. Among the many human activities transportation plays a considerable role in contributing to CO2 emissions. In the future transportation is projected to grow further on and since other energy consuming sectors are unable to compensate for transportation related emissions, therefore the transportation sector has to contribute to emissions abatement. Using environment friendly energy resources is the only way to reduce environmental load without restricting mobility. One way to decrease CO2 emissions of the transportation sector is the application of biofuels. The aim of this paper is the theoretical estimation of the environmental impact of ethanol─gasoline and diesel oil─ethanol─biodiesel blends respectively.
