The i-Tree Planting Calculator

The i-Tree Planting Calculator is designed to help you estimate the long-term environmental benefits from a tree planting project. The focus is on greenhouse gases, but many co-benefits are included.

Users enter the following information:

• Tree species
• Size of trees at planting
• Information on the distance and direction to the nearest building (optional)
• Information about the tree’s growing conditions
• Estimated mortality (optional)
• The number of trees with each configuration
• Project lifetime (number of years)
• Specific greenhouse gas values (optional)

The following information is calculated (in units and associated dollar values) for the project life time:

• Greenhouse Gas (GHG) sequestered and avoided (owing to reductions in energy use)
• Energy conserved
• Air pollutants captured and avoided
• Stormwater filtered
• Tree aboveground biomass
