Battery Passport Carbon Intensity Calculator

Add up upstream material emissions and manufacturing energy to produce the carbon intensity metrics mandated for battery passport submissions, with optional adjustments for certified recycling credits.

Sum of upstream material and component emissions for the battery pack.
Electrical energy consumed during cell formation, assembly, and testing.
Carbon intensity of the electricity serving the manufacturing site.
Nominal usable energy content of the pack.
Defaults to 0%. Enter certified end-of-life recycling credit if allowed under the reporting scheme.

Ensure lifecycle data sources align with the regulatory year of compliance and document any supplier-specific adjustments.

Examples

  • 3,200 kg materials, 45,000 kWh manufacturing at 0.45 kg/kWh, 90 kWh pack, 5% credit ⇒ Total cradle-to-gate emissions: 22,277.50 kg CO2e
  • 2,800 kg materials, 30,000 kWh manufacturing at 0.35 kg/kWh, 75 kWh pack, credit blank ⇒ Total cradle-to-gate emissions: 13,300.00 kg CO2e

FAQ

Which materials belong in the supply chain emissions input?

Include cathode, anode, electrolyte, separator, casing, and electronics emissions as reported by suppliers or lifecycle databases. Freight and packaging can be added if required by the reporting jurisdiction.

How precise must the grid intensity be?

Use the emission factor from the utility, residual mix, or contractual energy instrument covering the manufacturing site. High-volume exporters often rely on annual residual mix data published by the International Energy Agency or EU member states.

When can I claim a recycling credit?

Only apply credits when the reporting scheme recognises documented end-of-life recycling agreements or secondary material content. Enter zero if the credit has not been independently verified.

Does the result need to be reported in kg CO2e/kWh or g CO2e/Wh?

EU battery passport templates typically ask for kg CO2e/kWh, while some OEM scorecards request g CO2e/Wh. The calculator outputs both to streamline disclosures.

Additional Information

  • Manufacturing emissions equal process energy multiplied by the grid carbon intensity for the factory location.
  • Summing material and manufacturing emissions gives the cradle-to-gate footprint required for EU battery passport reporting.
  • Dividing net emissions by pack capacity yields the kg CO2e per kWh intensity; the same numeric value applies to g CO2e per Wh.
