Energy consumption and CO_2 emission in transportation sector: A comparison among BRIC Countries

摘要

With the growth of population and vehicles, transportation sector is taking up the major share of energy consumption and CO_2 emission in BRIC Countries. This paper is intended to analyze the energy, emission and environmental situation of the transportation sector in BRIC Countries from an energy point of view. Historical data is used to investigate the energy consumption in BRIC Countries from 1990 to 2009. A method of calculating CO_2 emissions is employed in transportation sector of BRIC Countries. The total CO_2 emission and emission from sub-sector of transportation in CO_2 emissions of the four countries are described. The polices to reduce energy consumption and emissions are suggested to give a richer understanding of current status in transportation environment of BRIC Countries.
