Carbon Footprint Methodology for Automotive Products
2.3 Calculation Methodology
■Vehicle production stage
Carbon emissions from energy consumption and escaping in vehicle production process
Carbon emissions from vehicle production = carbon emissions from energy or fuel production +
carbon emissions from energy or fuel use +CO₂ emissions leakage
C production = Σ (E,
ΣΕ,
Σ (E₁ × CEF, + E₁ × NCV, × CEF, ) + M co₂
