Description
Allocate a signed inventory contribution using supplied coproduct weights.
Environmental inventories distinguish wet/dry material, analytical detection limits, gas-volume reference states, represented area and allocation weights. A monitoring completeness fraction can exceed one when extra records are present. Supplied conversion and allocation factors need separate justification before physical or environmental interpretation.
Allocate a signed inventory contribution using supplied coproduct weights.
When to use this tool
Use Emission Allocation Single Coproduct Share when checking the stated environmental reporting, analytical, inventory or support convention.
How to use the tool and how it works
- Enter totalInventory, coproductWeight, totalWeights. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read allocatedInventory, allocationShare. Use the output convention below.
Require nonnegative coproduct weight within positive totalWeights. Return weight/total share and signed totalInventory*share.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| totalInventory | Signed inventory on the chosen allocation basis; negative values are accepted. | Required. Finite number. |
| coproductWeight | Coproduct Weight | Required. Finite number; minimum 0. |
| totalWeights | Total Weights | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| allocatedInventory | Allocated Inventory | Required. Finite number. |
| allocationShare | Allocation Share | Required. Finite number. |

}Limitations and assumptions
- Weighting basis and system boundary are supplied; no full life-cycle allocation, actual emissions or an appropriate allocation method is determined.
- 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 calibrated representative measurements and appropriate complete analytical, spatial or life-cycle methods for actual environmental conclusions and compliance decisions.
