Description This study reports the rate of gaseous emissions due to road transport in Maiduguri Metropolis, Nigeria. The technique used involved the determination of the rate of fuel (petrol and diesel) consumption by vehicles in Maiduguri, together with the fuel emissions factors. Data were collected through formal interactions with Filling Stations managers in the city to get information on the daily rates of fuel consumptions. To obtain the net fuel consumed by the road transport sector only within the city, fuel consumed by other sectors such as domestic, industry and business as well as fuel consumed by road vehicles outside the city were also estimated for subtraction from the total. With the emissions intensity of each fuel by vehicle type known from literature, the emissions rates of greenhouse gases (in CO2 equivalent) and criteria gases were evaluated using the relevant emission conversion factors. It was found that the daily rate of emissions due to road traffic in Maiduguri as at early 2017 stood at about 71.5t/day for CO, 9t/day for NMVOC, 8.2t/day for NOx, 0.03t/day for PM, 0.09t/day for N2O, 0.4t/day for NH3 and 887.2t/day for CO2. In CO2 equivalent, greenhouse gas emissions rate is estimated to be 913tCO2e/day. It shows that the annual emissions rate of CO2 gas in Maiduguri is therefore 0.324mtCO2e/year and that of greenhouse gas (GHG) is 0.333mtCO2e/year. This figure is likely to constitute health hazard to the city.
