Abstract :

This work investigated and analysed the contribution of commercial vehicles to the emission of GHGs in Makurdi, Benue State, Nigeria so as to understand the pattern of emission and provide policy makers and other stakeholders a clear picture of the situation at hand and provide them with suggestions on how to clamp down on the emission from commercial vehicles in the state capital. In doing this, data on the five main types of commercial vehicles in Makurdi (i.e. buses, motorcycles, saloons, tricycles and trucks) on the distances and routes travelled and amount of fuel consumed were collected using questionnaires. North bank, Warefare Quarters, Modern Market, Air force Base and Wadata were the routes considered using Wurukum as the starting point. Using two methods of analysis (based on fuel consumed and that based on travel distance), it was found that commercial vehicles emitted 7,385.06tCO2e and 6,328.713tCO2e respectively. It was also found that buses emitted the highest quantity of GHGs while tricycles were responsible for the least; 40% of all emissions were recorded from activities on Air Force Base route while North bank and Warefare Quarters recorded approximately 14% each; Modern Market route recorded about 21% of the emission while Wadata route recorded the least amount of emission with about 11% of the total emission. The study established that that the emissions were high compared to standard emission values as the per passenger emission from all types of commercial vehicles (with the exception of tricycles) were found to be above the World Bank’s data of per capita emission for the country. This means more needs to be done to reduce the emission to at least the average value obtainable in the country.
