Tree Benefits Calculator
Scale user-entered model outputs by tree count.
Inputs and method
Each scenario value = tree count × the entered per-tree-year model output.
All empirical factors, rates, percentages, clearances, product yields, and model values shown as inputs are scenario values supplied by you. Their source or measurement basis appears beside the inputs and result. Units remain visible, calculations use unrounded values, and rounding occurs only for display or a whole-package ceiling.
Interpreting the result
Record model, version, location, species, and calibration. No generic coefficient, oxygen, money, energy, or air-quality claim is supplied.
Treat scenario ranges as sensitivity ranges, not confidence intervals. Check the factor’s version, geography, population or product, system boundary, and date before using the result. A numerical result does not establish code compliance, certification, safety, forecast accuracy, or model validity.
Validation and rounding
Blank required factors, invalid numbers, prohibited negatives, impossible relationships, and unsupported modes trigger a validation message. Results are rounded as stated; package quantities round up only after waste is applied.
Worked example
For 3 trees, entered model outputs of 20 kg/tree-year and 2 m³/tree-year produce 60.0 kg/year and 6.0 m³/year.
Frequently asked question
Are these guaranteed environmental benefits? No. They are entered model outputs multiplied by tree count.
