Carbon Footprint Calculation and Battery Passport

Battery Carbon Footprint

A battery's carbon footprint is the sum of greenhouse gas emissions throughout its entire lifecycle, from raw material extraction to end of life. This value is an important indicator of the battery's sustainability performance.

Life Cycle Analysis (LCA)

Carbon footprint calculation covers these stages:

Raw Material Extraction: Mining and processing
Material Production: Cathode, anode, electrolyte production
Cell Manufacturing: Manufacturing of battery cells
Pack Assembly: Battery pack and BMS integration
Transportation: Logistics and distribution
Use: Charge-discharge cycles
End of Life: Recycling or disposal

EU Carbon Footprint Requirements

Carbon footprint declaration under EU Battery Regulation:

February 2025: Carbon footprint declaration mandatory
August 2026: Performance classification (A-E)
2028: Maximum carbon footprint limits

Calculation Methodology

EU-approved calculation methodology:

Compliance with ISO 14067 standard
kg CO2 equivalent / kWh unit
Cradle-to-gate approach (up to factory gate)
Use of verified data sources
Third-party verification requirement

Emission Sources

Carbon footprint distribution of a typical EV battery:

Raw material extraction: 20-25%
Active material production: 30-40%
Cell manufacturing: 25-35%
Pack assembly: 5-10%
Transportation: 5-10%

Reduction Strategies

To reduce carbon footprint:

Production with renewable energy
Use of recycled materials
Supply chain optimization
Energy-efficient production processes
Low-carbon raw material sources
