The world is undergoing rapid development and urbanization as a result of indiscriminate timber harvesting, burning of residues, and unauthorized waste disposal. These has led to increased carbon emissions that have greatly contributed to greenhouse gases and global warming. Therefore, this study was carried out to assess the amount of carbon stock of avenue trees around the Western Gate of Adekunle Ajasin University, Akungba-Akoko, which contributed to the environment. Enumeration was considered for this study because it is possible to count all the trees in the study area and all the trees with DBH≥10 cm were assessed. The avenue trees were identified, enumerated, and measured for diameter at the base, middle, and top, along with tree height. Wood density values were sourced from existing literature to estimate biomass, carbon, and carbon dioxide content. A total of 124 tree species were identified and recorded, representing 18 species across 11 families. The results show that, Gmelina arborea exhibited the highest carbon stock at 25.34 kg and carbon dioxide sequestration at 93.00 kg, followed by Acacia auriculiformis, which sequestered 4.67 kg of carbon and 17.16 kg of carbon dioxide. In total, the avenue trees in the study area sequestered 94.14 kg of biomass, 47.07 kg of carbon, and 172.75 kg of carbon dioxide. Hence, the findings showed the significant potential and contributions of the avenue trees around the Western Gate in absorbing atmospheric (CO2). This has contributed immensely to climate change mitigation and amelioration efforts on the University Campus.
