\[CF_{unit}=\frac{E_{CO2e}}{N_{prod}}\]
Variables
CFunitcarbon footprint per product unit (kg CO2e/unit)
ECO2etotal carbon dioxide equivalent emissions (kg CO2e)
Nprodnumber of product units produced
Description
What is this formula?
This formula calculates the carbon footprint allocated to each unit of product.
When to use it
Use it when estimating product-level emissions from total CO2-equivalent emissions and production quantity.
Example
Data:
ECO2e = 12000 kg CO2e
Nprod = 3000 units
Formula:
CFunit = ECO2e / Nprod
Substitution:
CFunit = 12000 / 3000
Result:
CFunit = 4 kg CO2e/unit
Applications
Product carbon footprinting, sustainability reporting, ESG indicators, manufacturing analysis, life cycle assessment screening, and environmental benchmarking.
Note
This is an allocation-based indicator. Results depend on the emission boundary, production period, allocation method, and whether direct, indirect, or life-cycle emissions are included.
