Description
Return adjustedIncome = baselineIncome*incomeMultiplier and damage = baselineIncome*damageFraction*incomeMultiplier^incomeElasticity.
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 adjustedIncome = baselineIncome*incomeMultiplier and damage = baselineIncome*damageFraction*incomeMultiplier^incomeElasticity.
When to use this tool
Use Climate Damage Income Base Factor when checking one declared valuation or equivalence contribution.
How to use the tool and how it works
- Enter baselineIncome, incomeMultiplier, damageFraction, incomeElasticity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read adjustedIncome, damage. Use the output convention below.
Require nonnegative baselineIncome, positive incomeMultiplier and damageFraction in [0,1]. Return adjustedIncome = baselineIncome*incomeMultiplier and damage = baselineIncome*damageFraction*incomeMultiplier^incomeElasticity. incomeElasticity is a dimensionless signed exponent.1

}Limitations and assumptions
- Damage scales baseline income by an elasticity adjustment; it is not automatically adjustedIncome*damageFraction. The result can exceed adjusted income for some inputs and is not clamped. No climate damage function or ethical income weighting is inferred.
- 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.
