ABSTRACT
The amount of CO2 emissions from the transportation sector accounts for a large proportion of total emissions. However, reducing CO2 emissions in this sector is relatively difficult because of a growing population, a higher share of automobile owners, and an improvement in infrastructure, which all contribute to emissions. Although the total aggregated greenhouse gas (GHG) emissions of Annex 1 parties decreased overall from 1990 to 2004 in the majority of energy-consuming sectors, the transport and energy industry sectors were exceptions (Meyer et al., 2007). Thus, the reduction of emissions in the transportation sector is an important problem facing both developed and developing countries.
