Abstract: We have adopted the Divisia index approach to study the effects of five factors on the total emissions of carbon dioxide (CO2) arising from highway vehicles in Tunisia during the period ranging from 1980 to 2011. CO2 emissions have been decomposed into five factors, namely emission coefficient, vehicle fuel intensity, vehicle ownership, population intensity and economic growth. We show that fast-paced economic growth and vehicle ownership have been the most important factors which have participated in the augmentation of CO2 emissions, while population intensity has contributed significantly to the decrease of emissions.
