Green Carbon – Nature’s CO₂ Storage Powerhouse

Green carbon refers to carbon absorbed by trees, forests, and vegetation-covered lands through the process of photosynthesis, with carbon dioxide (CO₂) as the key element. These ecosystems are vital carbon sinks, just like blue carbon ecosystems that store CO₂ in coastal and marine environments.

The most powerful green carbon sink is the forest—due to its long lifespan and ability to continuously store carbon over decades or centuries. Even the fallen leaves, branches, and organic debris on the forest floor store carbon for years, contributing to the global carbon cycle.

Because forests can store vast amounts of CO₂, afforestation (planting new forests) and reforestation (restoring degraded forests) are essential for enhancing green carbon storage capacity and combating climate change.

How Much CO₂ Can Different Tree Species Absorb per Rai?

(1 rai = ~0.16 hectare or 0.4 acre)

• Dalbergia cochinchinensis (Siamese Rosewood) – 100 trees/rai: 1.36–2.16 tons CO₂/rai/year
• Eucalyptus – 267 trees/rai: 3.15–6.09 tons CO₂/rai/year
• Acacia mangium – 178 trees/rai: 4.00–6.09 tons CO₂/rai/year
• Mangrove – 711 trees/rai: 0.77–6.49 tons CO₂/rai/year
• Rubber tree – 144 trees/rai: 4.22 tons CO₂/rai/year
• Oil palm – 144 trees/rai: 2.49 tons CO₂/rai/year
• Slow-growing native species – 100 trees/rai: 0.95 tons CO₂/rai/year
• Urban-planted species – 50 trees/rai: 1.21 tons CO₂/rai/year

(CO₂ absorption varies depending on tree age, species, soil fertility, and climate conditions.)

Five Main Carbon Storage Components in Trees and Forests

1. Above-ground biomass – trunks, branches, and leaves
2. Below-ground biomass – roots
3. Deadwood – standing or fallen dead trees
4. Litter – fallen leaves, twigs, and plant debris
5. Soil organic matter – carbon stored in soil

Additional Insight

According to IPCC and FAO reports, tropical forests like those in Southeast Asia are among the most efficient green carbon sinks, storing an average of 150–250 tons of carbon per hectare. Planting fast-growing trees such as eucalyptus and acacia can rapidly absorb CO₂ in the early years, but integrating native species improves long-term biodiversity and resilience.

Mangroves are particularly important because they store carbon both above and below ground, often in deep soils that can hold carbon for centuries—making them critical for both green carbon and blue carbon benefits.

If Thailand increased tree cover by just 1 million rai, it could potentially absorb 3–5 million tons of CO₂ annually, significantly contributing to the country’s net-zero targets.

Can Oklin Food Waste Composters Really Help Reduce Global Warming?

Yes — and here’s how much.

• Over 4,117 tons (4,116,840 kg) of food waste processed annually
• 164,673 kg/year reduction in methane emissions from landfills
• Up to 10,415,000 kgCO₂e/year reduction in carbon footprint

The Oklin food waste composter uses biotechnology to break down food waste efficiently. It can reduce food waste volume by 80–90% within just 24 hours, producing high-quality organic fertilizer as the end product. This fertilizer can be used as a soil conditioner, leaf and fruit growth booster for agricultural crops, or to nourish trees in landscaping projects.

By preventing methane emissions—a greenhouse gas over 28 times more potent than CO₂—and producing organic fertilizer that supports sustainable agriculture, Oklin composters make a direct and measurable impact on climate change mitigation.
