The purpose of this study was to estimate carbon storage and sequestration by urban forest, to predict future sequestration potential through planting and growth, and to suggest urban forest planting to arrest Global warming. The results as follows; 1. Tree carbon store by study urban forest averaged 29,462kg-C/ha and ranged from 8kg-C/ha to 124,087kg-C/ha. 2. Carbon sequestration by study urban forest averaged 2,179kg-C/ha・yr and ranged from 35kg-C/ha・yr to 3,969kg-C/ha・yr. 3. The elapsed years after planting influence carbon sequestration per ha.
