Carbon dioxide (CO2) is one of the most abundant greenhouse gases and a primary agent of global warming. It constitutes 72% of the total anthropogenic greenhouse gases, causing between 9-26% of the greenhouse effect. This study focused on carbon-dioxide sequestration potential of trees in four tertiary institutions (Federal University of Technology Akure, Adekunle Ajasin University Akungba Akoko, Rufus Giwa Polytechnic, Owo, and Federal College of Agriculture Akure) in Ondo State, Nigeria. Identification of trees located in built up areas, car parks and walk ways of each institution was done with an experienced taxonomists. Tree variables such as diameter at breast height (dbh), diameter at the base (Db), diameter at the middle (Dm), diameter at the top (Dt) and total height (Ht).) were measured using Spiegel relaskop and girth diameter tape. Carbon storage estimation was estimated using non-destructive method. Of the 100% CO2 in the institutions under this study, AAUA had 92.22%, FUTA had 3.40%, RUGIPO had 4.99% and FECA had 0.59% respectively. The amount of carbon-dioxide estimated for each institution in this study were comparably higher than what was obtained for Strict Nature Reserve (593.68 tons/ha) and Enrichment Planting Forest (326.14tons/ha). This study is an eye opener that much more carbon-dioxide could be sequestered if more trees are planted or retained in our tertiary institutions. Therefore, retention and planting of tree species in our tertiary institution is recommended.
