This comparative study of carbon sequestration in Tectona grandis L.f. and Azadirachta indica A.Juss. at Baan Suan Prathanporn, Na Yong Tai Subdistrict, Mueang District, Trang Province, aimed to: 1 ) assess the total carbon sequestration in the biomass of Tectona grandis L.f. and Azadirachta indica A.Juss. in the area. It was found that Tectona grandis L.f. sequestered more carbon in their total biomass than Azadirachta indica A.Juss. Tectona grandis L.f. sequestered 2,796.28 kg of carbon, representing 54.80% of their total carbon, while Azadirachta indica A.Juss. sequestered 2,306.81 kg of carbon,representing 45.20% of their total carbon. 2) analyze and compare the carbon sequestration potential in the biomass of Tectona grandis L.f. and Azadirachta indica A.Juss. .Tectona grandis L.f. showed greater potential for carbon sequestration than Azadirachta indica A.Juss. . 3) study the economic return of carbon credits from Tectona grandis L.f. and Azadirachta indica A.Juss. . The results showed that the return on carbon credits from Tectona grandis L.f. and Azadirachta indica A.Juss. depends on the amount of carbon absorbed by the trees. Tectona grandis L.f. have a high potential for carbon sequestration when they are older and have a larger circumference, making them more valuable. Azadirachta indica A.Juss. are popular in climate change mitigation projects because of their rapid growth and carbon sequestration potential. Azadirachta indica A.Juss. are notable for their height, while Tectona grandis L.f. are notable for their girth, resulting in Tectona grandis L.f. having a higher biomass and greater long-term value. Both tree species generate income from selling carbon credits under the Thailand Voluntary Emission Reduction Program (T-VER) to polluters such as industrial plants and companies with high greenhouse gas emissions, according to research by CarbonWatch (Assessment of Carbon Sequestration in the Forestry Sector and Forest Management). Therefore, Tectona grandis L.f. and Azadirachta indica A.Juss. offer significant economic returns in terms of carbon credits.
