production Ideal LCA calculation: Track each component of each vehicle an
Supply chain is complex, hence need simplification for calculation of carbon footprint
Impractical to track minute/minute energy consumption=> Average value of a duration (12 months /24 months etc.)
Impossible to track individual sourcing =>Average value of production =>Secondary data set
Individual vehicle need not be calculated as this will not give additional benefit but can add burden of calculation => Representative vehicle<br>
