There were 362 tree counts are recorded with Crescentia cujete showed better carbon sequestration potential rate with 0.321 tons/tree of carbon and Muntingia calabura has the lowest sequestration rate which sequestered 0.004 tons/tree of carbon as compared to other species. An average of 0.113 tons per tree carbon is sequestered and total carbon sequestered 40.842 tons/ tree in the CASFOS Campus. This study helps to improve the carbon sequestration areas to reduce the atmospheric carbon and act as carbon sinks in urban areas. 1.0 Introduction Carbon sequestration is the removal of carbon-dioxide from the atmosphere and stored in the terrestrial forms for more time. Plants store carbon in the form of biomass in all its parts. CO 2 is absorbed naturally by photosynthesis by plants and is a natural process 1,2 . e CO 2 sinks and store the excess carbon in the form of biomass, which driven by photosynthesis. is biomass stores in all parts of plants 2-4 . e increased air pollution, mainly due to increased CO 2 level from developmental activities led to global warming as it is the major greenhouse gas. us, increases the temperature of the atmosphere through greenhouse effect. is is the main concern in Kyoto Protocol and Montreal Protocol 5 . Terrestrial vegetation and soil are considered to be main carbon sinks 6 , and accounting for 24 percent of net annual anthropogenic emission of greenhouse gases to the environment 7 . An estimation stated that the standing biomass and carbon sequestration potential of multipurpose tree species at Mohand Range of Dehradun Forest Division in Uttarakhand revealed a carbon storage of 56.7% in Albizzia lebbeck and 48.7% in Eucalyptus tereticornis 8 . e experimental study showed carbon sequestration capacity of Dalbergia sissoo increased biomass and carbon sequestration during 8 th ,16 th, and 24 th months period of time aſter plantation 9 . A study recorded higher carbon sequestration capacity of wild mango trees varieties compared to cultivated graſted mangoes occupied degraded lands of lateritic origin in the Konkan region of India 10 . A review stated that different groups of tree species for afforestation-driven soil organic carbon sequestration and showed less variation in the SOC sequestration rates in deciduous broadleaved, evergreen broadleaved and evergreen conifer relatively than evergreen and deciduous, or broadleaved and conifer forests 11 . Soil potential to store organic carbon in agroecological region is also depend on the crops grown in the region as they influenced by the nitrogen and other chemical factors in the soil 12 . Hence carbon sequestration
