Tree Benefits Calculator — Ecosystem Services Estimator
How much do your trees do for the environment? Enter the number of trees, their size, and how many years to project — then see estimated CO₂ sequestration, stormwater intercepted, energy savings, and air pollutants removed. All values are based on typical USFS i-Tree urban forestry data and are fully editable.

How does this calculator work?
Multiply a tree's annual per-tree benefits (CO₂ ~6–48 kg, stormwater ~950–7600 L, energy ~$15–90, air ~0.5–5 kg pollutants) by the number of trees and years to get lifetime totals. Default values are from USFS i-Tree Eco urban forestry data (temperate North America, 2020–2023) and are fully editable.
Formula
How this is calculated
Trees provide ecosystem services that have real, quantifiable value. This calculator uses per-tree annual benefit estimates from the US Forest Service's Urban Forest Effects (UFORE) model, popularly known as i-Tree Eco. Default values are typical for urban trees in temperate North America (data circa 2020–2023) — small trees (< 15 cm DBH), medium trees (15–45 cm), and large trees (> 45 cm) have different default values reflecting their canopy size and biomass. You can override any value to match your species, climate, or local study data.
CO₂ sequestration reflects net carbon stored in the tree's biomass each year — roughly 50% of the dry weight of wood is carbon, and each kilogram of carbon represents ~3.67 kg of CO₂. Stormwater interception counts rainfall that the canopy intercepts and evaporates before it reaches the ground, reducing runoff volume. Energy savings come from shading in summer and windbreak effects in winter — values are most significant for trees planted on the west/south side of buildings. Air quality figures combine particulate matter (PM2.5), ozone, nitrogen dioxide, and sulfur dioxide removed through leaf uptake and particulate capture.
The optional monetary CO₂ estimate uses a reference price of $50 per tonne of CO₂, roughly the 2024 EU Emissions Trading System average. Actual carbon prices vary by market, jurisdiction, and year — adjust the CO₂ rate field to match current prices if needed.
Frequently asked questions
Defaults are typical values from the USFS i-Tree Eco urban forestry model for temperate North American cities. They represent average conditions — actual benefits vary by species, climate zone, soil moisture, and tree health. Use the editable fields to enter local or species-specific data from an i-Tree report for your area.
Sequestration is the net new CO₂ captured each year as the tree grows — this is the figure used here. Total storage is the cumulative CO₂ locked in the tree's biomass since it sprouted. A mature tree stores far more than it sequesters annually, but that carbon is only "released" if the tree dies and decays or is burned.
Values vary significantly by climate. Trees in humid subtropical climates typically intercept more stormwater; trees in hot-arid climates provide larger cooling savings; northern cold-climate trees grow more slowly so they sequester less CO₂ annually. The editable fields let you enter data appropriate for your region.
