Description
Return attributedQuantity = emittedQuantity*attributedShare and damageContribution = attributedQuantity*suppliedDamagePerUnit.
Environmental valuation assigns monetary or credit quantities to a defined change using explicit factors. Area prices, exposure damages, income adjustments and ecological equivalences embody different assumptions; multiplying them does not validate those assumptions.
Return attributedQuantity = emittedQuantity*attributedShare and damageContribution = attributedQuantity*suppliedDamagePerUnit.
When to use this tool
Use Pollutant Damage Weight Contribution when checking one declared valuation or equivalence contribution.
How to use the tool and how it works
- Enter emittedQuantity, suppliedDamagePerUnit, attributedShare. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read attributedQuantity, damageContribution. Use the output convention below.
Require nonnegative emittedQuantity and attributedShare in [0,1]. Return attributedQuantity = emittedQuantity*attributedShare and damageContribution = attributedQuantity*suppliedDamagePerUnit. Use damage currency per the supplied emission quantity unit.1
| Input field | Meaning and units | Accepted input |

| emittedQuantity | Emitted Quantity | Required. Finite number; minimum 0. |
| suppliedDamagePerUnit | Supplied Damage Per Unit | Required. Finite number. |
| attributedShare | Attributed Share | Required. Finite number; minimum 0; maximum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| attributedQuantity | Attributed Quantity | Required. Finite number. |
| damageContribution | Damage Contribution | Required. Finite number. |

}Limitations and assumptions
- Attribution and damage factors are supplied assumptions. Negative damage factors remain signed; this term does not infer causation, atmospheric fate, exposed populations or a complete damage valuation.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use an appropriate empirical model and examine transferability, causal attribution and double counting before interpreting a complete environmental benefit estimate.
