CO2e per Unit with allocated co2e emissions of 24,300 kg CO2e: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop allocated co2e emissions to 24,300 kg CO2e, then walk the calculation through step by step. Calculate product carbon intensity from total CO2e emissions, production volume, and allocation factor.

The inputs for this scenario

  • Allocated CO2e emissions: 24,300 kg CO2e (the input this scenario stresses; the baseline uses 48,500)
  • Production volume: 12,500 units (held at the documented default)
  • Unit conversion or allocation factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw carbon intensity = allocated CO2e emissions รท production volume.
  • Reported CO2e per unit works out to 1.94 kg CO2e / unit at these inputs, and this is the headline figure for the scenario.
  • Raw carbon intensity works out to 1.94 kg CO2e / unit at these inputs.
  • Unit conversion or allocation factor works out to 1 x at these inputs.
  • Production volume works out to 12,500 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where allocated co2e emissions sits at 48,500 kg CO2e and the headline result is 3.88 kg CO2e / unit, this scenario comes in 49.9% below the baseline at 1.94 kg CO2e / unit.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to allocated co2e emissions, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The result is only as credible as the emissions allocation; how you split shared utilities, scope boundaries, and co-products across lines can swing the number substantially.
