Promoting Utilization of Biofuels in The Transportation Sector to Reduce CO2 Emissions: Comparative Analysis

Abstract

In this study, due to the high contribution of the transportation sector to generate CO2 emissions, an evaluation for the best scenario of the replacement of petroleum derived fuels by renewable and sustainable alternatives was assessed with a multi collative approach suggesting the second-generation bioethanol as the most promising one. In this context, this paper focused on the practices over the past 23 years in the following four countries; Turkey, China, Sweden, and Brazil, with a comparative regression analysis between the CO2 emissions generated from the consumptions of total energy and biofuels. Accordingly, a curve-fitting and an estimation on the formation of CO2 emissions with the incrementing blends of gasoline by 3 to 100% of bioethanol was forecasted for 2020 to 2030. The outcomes of the comprehensive research indicated the international and national benefits of biofuel use, thus, promoting the potential integration of bioethanol in the Turkish transportation sector.
