Over the years, there has been an increase and significant growth in the volume of motorcycle use in many Nigerian cities including Kano. Kano city is an ancient city and commercial nerve of Northern Nigeria. Motorcycles are used both as a personal and “for hire” transport mode. The increase in the growth of motorcycle uses is partly in response to a vacuum created by declining public transport facilities.
However its operations in Kano city are synonymous with serious and fatal accidents and other environmental hazards.
Consequently, the objective of this paper is to highlight the comparison between the need and environmental degradation of motorcycle use in Nigerian cities, using Kano as case study.
Cordon Count and emission study were carried out. In addition, Focus Group Discussion (FGD), questionnaire administration and scheduled interview were also used.
Findings from the study revealed that from a total of 1,977,925 motorcycles that were counted within selected areas within Kano metropolis, the average Carbon monoxide emissions rate of 3.2% hydrocarbon emission rate of 4643 ppm and carbon dioxide at 4.37% with air coefficient of 1.12 were recorded. The health implications were notable.
Finally, Policy decisions are expected to be made on the establishment of emissions checking centres across the metropolitan Kano. Also Pollution Under Control (PUC) Certificate, should be introduced
