摘要

Carbon dioxide, a vital greenhouse gas plays a key role in Earth's carbon cycle, a concentration above ambient temperature results in global warming. High CO_2 emission in Universiti Tun Husein Onn Malaysia is due to an increase in a number of automobiles and other greenhouse gases released from building facilities and nearby industries. A study was carried out on 22 common trees planted within the campus on the estimated amount of CO_2 sequestered. Estimation of carbon storage of trees was obtained through the assessments of standing biomass as well measurement of their photosynthetic capacity. Results indicated that Spathodea campanulata has the highest CO_2 absorption (14.40 μmol/ m^(-2)/s^(-1)) followed by Acacia mangium (14.03 μmol/m^(-2)/s^(-1)), and Cananga odorata with (12.80 μmol m^(-2) s^(-1)). Alstonia scholaris has the highest aboveground standing biomass accumulation of 106.94 kg, followed by Samanea saman (20.83 kg), and Acacia mangium (19.43 kg). The total biomass accumulated of all the tree species is 200.03 kg. Therefore, species of trees in Universiti Tun Husein Onn Malaysia main campus have the potential to absorb a significant amount of CO_2 from the atmosphere thereby contributing to mitigating-the localized effects of global warming.
