The Harvest Carbon Calculator

This USFS tool allows land managers and landowners to estimate the amount of carbon stored in harvested wood products. Estimates are based on harvest volume, geographic region, and wood type. It is entirely based off the PRESTO Wood Calculator

Potential Applications

Including harvested wood products in carbon accounting and carbon credits, exploring the carbon impacts of changing the amounts of longer- and shorter-lived wood products for a given forest stand.


1) A Stand Details report that gives estimates of carbon storage in tonnes per hectare for total carbon storage after 100 years (C100) and average annual carbon storage (CAvg). Estimates are given for five different storage categories. 2) A 10- year report which shows carbon storage calculations in 10-year increments for each of the five storage categories. Calculations can be exported to Excel.
