The aim of the study is to unveil urbanization environmental pollution with references to CO, CO2 emission concentration in Kano metropolis Nigeria. Carbon sensor and gas detector were employed for carbon emission concentration sensing and detecting. Geographical information system (GIS) was used for location map preparation. The results of the first six sampled local governments records depict that Fagge has the highest outdoor CO concentration of 12 Ppm, followed by Gwale with 11 Ppm and Kumbotso with exactly 10 Ppm. In contrary, the indoor records reveal that Gwale records the highest carbon concentration with 10 Ppm, followed by Fagge with 7 Ppm. In addition, the results of second four selected local governments with 12 selected stations indicates that CO2 concentration is very high in station A across the stations (A, B, and C) used as sensing points. The results portray that outdoor carbon concentration is far greater than indoor concentration due the facts that more outdoor carbon emission related activities in the study area are discovered. Indoor carbon concentration is affected by population elements, household sizes, age group, gender, education level and income levels of the residents. While outdoor carbon concentration is influence by transportation activities, industrial activities, type of land use, densities, and income categories of the dwellers. It is strongly recommended for an in-depth and proactive control for the rapid urbanization environmental pollutions impacts to be enforced in the study area. Researches on the topic to be furthered conducted in the study area and an in-depth study on the related topic should be regularly conducted within the metropolis so as to achieve environmental air quality control and proactive mitigating measures could be fully implemented.
