Free Tree Carbon Calculator to estimate tree carbon storage and CO₂ absorbed using accurate scientific formulas. Easy, fast, and reliable.
Climate change is a global problem. Trees are one of the strongest natural solutions. A tree absorbs carbon dioxide from the air and stores carbon in its trunk, branches, and leaves. But many people ask the same question. How much carbon is in a tree?
This is where a Tree Carbon Calculator helps. We developed this free tool so anyone can calculate tree carbon easily. You do not need science knowledge. You only need basic tree details.
This calculator gives fast, accurate, and easy-to-understand results.
Tree carbon means the amount of carbon stored inside a tree’s biomass. Biomass includes wood, bark, and leaves. Trees absorb CO₂ during photosynthesis. Oxygen is released. Carbon stays locked inside the tree.
This stored carbon helps reduce greenhouse gases and slows global warming.
Tree carbon is calculated using a scientific biomass formula. This method is recommended by forestry experts and climate researchers worldwide.
The calculation follows three steps.
This method is accurate and trusted.
The Tree Carbon Calculator uses the Chave allometric equation, which is widely accepted for tree carbon estimation.
Above-ground biomass formula:
AGB = 0.0509 × Wood Density × Diameter² × Height
Where
Carbon calculation formula:
Tree Carbon = AGB × Carbon Fraction
The default carbon fraction used is:
Carbon Fraction = 0.47
CO₂ equivalent formula:
CO₂ = Tree Carbon × 3.67
The value 3.67 comes from the molecular weight ratio of CO₂ to carbon.
The calculator will instantly show tree biomass, stored carbon, and CO₂ absorbed.
Let’s understand this with a simple example.
Assume a tree has a diameter of 30 cm.
The height is 15 meters.
Wood density is 0.60 g/cm³.
Biomass calculation:
AGB = 0.0509 × 0.60 × 30² × 15
AGB ≈ 412.7 kg
Carbon stored:
Tree Carbon = 412.7 × 0.47
Tree Carbon ≈ 194.0 kg
CO₂ absorbed:
CO₂ = 194.0 × 3.67
CO₂ ≈ 712.9 kg
This single tree removes more than 700 kg of CO₂ from the air.
The amount of carbon depends on tree size and species.
A small tree may store 10 to 50 kg of carbon.
A medium tree can store 100 to 300 kg.
Large mature trees can store over 1,000 kg of carbon.
Bigger trees store more carbon for longer periods.
One ton of CO₂ equals 1,000 kg.
On average, one mature tree absorbs about 20 to 25 kg of CO₂ per year.
This means around 40 to 50 mature trees are needed to absorb 1 ton of CO₂ in one year.
Using a Tree Carbon Calculator gives a more accurate number based on real tree data.
This tool is perfect for students, researchers, farmers, environmentalists, and climate-aware users.
The Tree Carbon Calculator is the easiest way to understand how trees fight climate change. It turns complex science into simple numbers. With just a few inputs, you can see how much carbon a tree stores and how much CO₂ it removes.
If you care about the environment, this calculator helps you see the real impact of trees.
The calculator uses internationally accepted biomass equations and IPCC carbon factors. Accuracy increases when correct wood density is used.
Yes. This is a 100% free Tree Carbon Calculator with no limits.
Yes. It works for most tree species. For best results, use species-specific wood density.
Yes. It shows both stored carbon and CO₂ equivalent.
Because research shows about 47% of dry tree biomass is carbon. This is the global standard.
