Environmental Comparison of the Use of Biodiesel and Gasoline for Transportation — A Case Study for Athens

Energy usage, in the Greek transport sector, takes the form of gasoline consumption by automobiles, diesel oil for taxis, trucks, maritime transport, and railroads as well as jet fuel for aircraft. The control of CO2 emissions constitutes a major environmental issue in most countries and many authorities seek to stabilize or decrease these emissions. During the past decade, biofuels in the form of blended gasoline and biodiesel have begun to find places in the energy economy since a sustainable transport future requires the reduction of CO2 emissions. The Greek car market shows a remarkably low rate in the penetration of biodiesel compared to the average European Union market. In this study we try to find out the combined effects of probable changes in biodiesel and gasoline future fuel consumption in the city of Athens.
