Tree Carbon Sequestration Calculator
Estimate how much CO2 a number of trees absorbs over a given number of years.

Understanding Tree Carbon Sequestration
Trees absorb carbon dioxide (CO₂) from the atmosphere through photosynthesis, storing the carbon in their trunks, branches, leaves, and roots. A commonly cited estimate is that a typical mature tree absorbs about 21 kg of CO₂ per year, though the exact amount varies widely by species, age, climate, and growing conditions. Over their lifetime, forests act as significant carbon sinks that help mitigate climate change.
How the Calculation Works
- Annual absorption: Number of trees × CO₂ absorbed per tree per year
- Total absorption (kg): Annual absorption × number of years
- Total absorption (tonnes): Total kilograms ÷ 1,000

Note: This calculator provides estimates based on an average CO₂ absorption rate per tree. Actual sequestration depends on tree species, age, size, climate, soil, and forest management. Use the default of 21 kg per tree per year as a general benchmark, or enter a species-specific value for more accurate results.
