Tree Eco-Value Calculator

Calculate environmental and economic benefits of trees

Formula

Benefits scale with DBH, species, condition, climate. CO2 @ $50/ton, O2 @ $20/ton, stormwater @ local cost, energy @ electric rate. Property value ~$100-120/inch DBH.

Based on USDA Forest Service i-Tree methodology. Trees provide ecosystem services: carbon sequestration, air purification, stormwater management, energy conservation, and property value enhancement.

How to Calculate Manually

3
Select tree condition
4
Enter distance to nearest building
5
Select climate zone
6
Enter local utility costs
7
Calculator shows annual and lifetime benefits

Reference Table

Tree Size (DBH)	CO2 (lbs/yr)	Stormwater (gal/yr)	Energy (kWh/yr)	Property Value
10"	400-550	15,000-22,000	1,200-1,800	$1,000-1,200
20"	800-1,100	30,000-45,000	2,400-3,600	$2,000-2,400
30"	1,200-1,650	45,000-65,000	3,600-5,400	$3,000-3,600
40"	1,600-2,200	60,000-85,000	4,800-7,200	$4,000-4,800

Tree Value Calculator: Environmental and Economic Benefits

Trees provide tremendous environmental and economic benefits that are often overlooked. The USDA Forest Service's i-Tree tools quantify these ecosystem services, showing that urban trees are critical infrastructure. A single mature tree can provide thousands of dollars in benefits over its lifetime...

Frequently Asked Questions

How is tree value calculated? Based on i-Tree methodology: CO2 sequestration, air pollution removal, stormwater interception, energy savings (shade/windbreak), property value increase, and avoided emissions.: Based on i-Tree methodology: CO2 sequestration, air pollution removal, stormwater interception, energy savings (shade/windbreak), property value increase, and avoided emissions.
What factors affect tree value? Species, size (DBH), condition, location, climate zone, proximity to buildings, and local utility/environmental costs.: Species, size (DBH), condition, location, climate zone, proximity to buildings, and local utility/environmental costs.
What is DBH? Diameter at Breast Height - tree trunk diameter measured at 4.5 feet (1.37 m) above ground. Standard forestry measurement.: Diameter at Breast Height - tree trunk diameter measured at 4.5 feet (1.37 m) above ground. Standard forestry measurement.
