Abstract: Emission-driven climate variability continues to receive great interest worldwide. Due to its negative impacts on human health and welfare, an accurate carbon dioxide (CO2) estimate is needed. There is a great need to control concentrations, and to monitor the environment and industrial processes of Owerri metropolis. This comparative study presents the measured concentration of CO2, relative humidity, temperature and wind speed. We concentrate on stations that have green plants and those of non-green plants over seven sites from January to April 2016. The results are compared with sixteen weeks of measurements from the suburb environment at Uratta in Owerri North LGA. Concentrations of CO2 were approximately 42.38 ppm higher during the rainy season than during the dry season over the non-green plant area. The results are representative of the biological surroundings and indicate the importance of intra-urban selection when characterising spatial and seasonal variation in surface characteristics of CO2.
