The objective of this research was to study and compare the carbon sequestration potential of various perennial tree species within Varee Chiangmai School, Chiang Mai. The study considered canopy cover, ground cover, tree height, and biomass calculations to determine the amount of carbon and carbon dioxide that the trees can sequester. The research results showed that canopy cover in steps 1–8 ranged from 50–70%, indicating moderate to high canopy density. However, in steps 9–10, canopy cover decreased significantly. Regarding ground cover, it was found that there was 0% green ground cover in every step because the entire area is paved with artificial grass, resulting in no natural ground cover plants in the study area. Regarding tree height and circumference, it was found that the Golden Shower Tree (Koon) had the greatest height and circumference, reflecting a high potential for biomass creation. When calculating biomass and carbon content, it was found that the Queen's Crape Myrtle (Inthanin Nam) sequestered the highest amount of carbon (2.5631 tons), followed by the Golden Shower Tree (2.4571 tons). The Silver Trumpet Tree (Lueang Pridiyathorn) sequestered the least amount of carbon (0.1454 tons). This demonstrates that morphology, height, circumference, and growth rate affect the carbon sequestration potential of each tree species. In conclusion, different types of perennial trees have different abilities to sequester carbon. The data from this study can be used to plan for increasing green spaces, selecting tree species with high potential for carbon absorption, and serving as an environmental learning resource for students in accordance with sustainable development guidelines
