Vehicle Carbon Emissions Concentration Level in Minna, Nigeria: The Environmental Cum Climate Change Implication

"This paper examines the trend of level of vehicular carbon footprints emissions in Minna, Niger State, Nigeria. It provides an insight into the obtainable emission levels in the selected flashpoints for the study. These flashpoints are spread across the city of Minna’s road network. The measurements were achieved using gasman meters for each type of gas investigated in this study namely: carbon dioxide (CO2), carbon monoxide (CO), sulphur dioxide (SO2), ammonia (NH3), nitrogen dioxide (NO2), chlorine (Cl2) and hydrogen sulphide (H2S). The measurements were carried out at the peak and off peak traffic times within the city due to temporal variations. The average emission values for the peak and off-peak times were calculated and also represented with the Arc-GIS software. The complete data have also been computed and analysed using the SPSS software. The results established that emissions’ level of carbon dioxide from vehicular emissions in particular exceeded the internationally accepted safe limits of 350 parts per million in the atmosphere. Upon the completion of this research, necessary measures for climate change mitigation via emissions reduction would be documented for effective and efficient urban and regional planning."
