How Much Carbon Can a Green District Store?

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.
