We've looked at how each part of a tree collects carbon and how much a tree can store (http://bit.ly/3M7OMbz). Let’s now see how much carbon green areas in The Forestias can store.​

RISC worked with a team from the Department of Biology in Chulalongkorn University’s Faculty of Science led by Asst. Prof. Pongchai Dumrongrojwatthana. The team collected data in June and July 2022 in the project's 4 green zones:
• Evergreen Forest ​
• Deep Forest​
• Edible Forest
• Fragrant Forest​

The data was used to calculate absorbed carbon dioxide by measuring tree diameter at breast height (130 cm from the ground) and using an allometric equation.​

Carbon dioxide stored differed between zones. The Evergreen Forest absorbed 254-314 kg of CO₂ equivalent over 10 square meters, followed by the Fragrant Zone (217-261 kg), Edible Zone (30-38 kg), and Deep Forest (6-8 kg). The different figures reflect the timing of tree planting and the varying growth rates of each tree.​

Regular measurement can gather additional information for managing green spaces, particularly in terms of carbon storage and further mitigation for global warming.​
