Park trees serve an important role in giving environmental advantages to humans. The i-Tree Eco model is used in this study to analyze the value of trees planted in 29/3 Park in terms of carbon storage capacity, carbon dioxide sequestration, and runoff avoidance. A total of 2,331 trees calculated in the 29/3 park are estimated to store about 122,540 kg of carbon, sequester roughly 24,490kg of carbon dioxide, and prevent 518.4m3 of runoff. The findings may be utilized to choose appropriate trees for future parks in Danang City to optimize environmental benefits.
