Abstract

World attention has been drawn to the climate change as a result of global warming. Carbon dioxide (CO2) is a greenhouse gas contributing 9-26 % to global warming. Hence this study focused on estimating CO2 emission from road transport system in Nigeria from 2004 – 2007. Inventory of all the automobile on the roads of the selected states in Nigeria was taken for the years under review. CO2 emission from this automobile was estimated using emission factor approach. The result showed Lagos state contributed highest total emission of CO2 with 116007706.2 ton/annum in the years under review while Cross River State contributed the lowest emission of 1170712.9 ton/annum. Also, motor cars contributed the highest emission of CO2 of 6720036.462 ton/annum to the ambient environment in the years under review while Lorries contributed lowest emission of 927541.18 ton/annum. The work provides an insight into the contribution of road transport system into the ambient level of CO2. The result from this work will help to put in proper legislation in reducing the emission of these pollutants.
