Welcome to the i-Tree Planting Calculator! v2.1.3

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.

This is a newly updated version of i-Tree Planting. Please clear your web browser's cache for this site before using.

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 total biomass

While i-Tree and its partners do not endorse any specific web-browser, the i-Tree Planting Calculator has been tested to work well with modern versions of Chrome, Firefox and Edge. Please, use the Feedback form to report issues.

There is a known issue where Chrome and Edge cannot load project files from the homepage. Please, go to the project page, and load saved files from there.
