Estimate tree carbon storage, CO2 equivalent, annual carbon sequestration, biomass, and potential carbon offset value. Use this tree carbon calculator for one tree, multiple trees, woodlots, landscaping projects, reforestation planning, and environmental estimates.
Diameter method:
The calculator uses DBH, tree type, and condition factors to estimate above-ground biomass, stored carbon, and CO2 equivalent.
Age method:
Enter tree age and annual CO2 sequestration per tree to estimate lifetime and project-period CO2 impact.
Known tree count:
Enter the number of trees to estimate total annual sequestration, surviving trees, and long-term CO2 impact.
Offset value:
The calculator multiplies estimated metric tons of CO2 by your entered carbon price to estimate potential offset value.
A tree carbon calculator helps estimate how much carbon trees may store and how much CO2 they may remove from the air over time.
It can be useful for homeowners, schools, nonprofits, landowners, forestry projects, environmental reporting, tree planting campaigns, and general carbon offset planning.
Your result shows estimated carbon stored, CO2 equivalent, annual CO2 sequestration, project-period CO2 sequestration, surviving trees, biomass estimate, and potential offset value. These numbers are estimates and should not be treated as verified carbon credits or official emissions accounting.
Carbon storage depends on tree size, species, wood density, age, health, and growing conditions. Larger, older trees usually store more carbon than small young trees.
CO2 equivalent converts stored carbon into the equivalent weight of carbon dioxide. One pound of carbon is roughly equal to 3.67 pounds of CO2.
No. This calculator provides an estimate only. Official carbon credits require approved methods, monitoring, verification, permanence rules, and registry requirements.
Survival rate helps estimate how many planted trees may remain alive and continue storing carbon over the project period.
