Urbanization and climate change: the role of road transport in carbon dioxide emission in Kano Metropolis, Nigeria

Abstract

Large cities are characterized by concentration of large number of people and centralization of commercial activities around their cores. These and consequently, emission of large amount of carbon dioxide (CO study aims to estimate the average amount of CO Kano Metropolis, Nigeria. The rela average density on the city's roads, estimating CO automobiles and examining the situation against CO Federal Government of Nigeria to the United Nations Framework Convention on Climate Change. Short period traffic count at various traffic corridors of the city was used to determine automobiles' average density per hour and United States Environmental Protection Agency method was used in estimating CO following emissions in metric tonnes per hour; 15.75 from cars and buses, 6.08 from tricycles and 0.56 from lorries. These give a combined hourly emission of 22.39 tonnes. CO measures identified are expansion of roads and construction of flyovers to decongest traffic. It is recommended that efficient public urban mass transit that involves low carbon emission should be provided and individual car usage should be discouraged

A Preliminary Study of Greenhouse Gases Emissions of Lagos Commercial Vehicles: the Intergovernmental Panel on Climate Change Guidelines at Work

“…Just like He et al (2005) and Otene, Murray & Enongene (2016) pointed out, transportation is highly dependent on fossil fuels and CO2 emissions from these fuels have been on a progressive rise and Nigeria is not an exception. With a population of over 158 million persons depending heavily on fossil fuel based transport in Nigeria, it becomes vital to understand the environmental impacts of the present road passenger transport sector as well as how these may change in the future as the sector continues to develop in its role in fostering development [Gujba, Mulugetta & Azapagic (2013); Rodrigue (2016) and Usman (2017)]. According to Okoli, Achebe & Anosike (2017) and Aminu & Asikhia (2019), a vehicle's emission is directly proportional to its fuel consumption.…”

A Comparative Analysis of Carbon Emissions in the Ecological Zones of Nigeria

“…Nigeria emits CO 2 and other greenhouse gases as a result of gas flaring during oil exploration. Although, there have been some studies on CO 2 emissions from urban transportation, the construction industry and energy consumption due to increase in population in the country (Okelola and Okhimamhe, 2013;Edeoja and Edeoja, 2015;Adusah-Poku, 2016;Usman et al, 2017), there are very few studies on the carbon emission rate from the vegetation on which the teeming population depends on for livelihood. This study therefore attempts to investigate the carbon emission rate in the different ecological zones in the country in other to suggest effective mitigation strategies to ameliorate the adverse impacts of climate change.…”
