3.3. Dependence on LC mileage This section investigates the dependence of sustainability indicators on LC mileage with the scope to quantify the sensibility of results with respect to operation distance. The following diagrams report the break-even point analysis for both reference and lightweight design variant as well as for all operation case studies considered. The left end of the graphs shows the contribution of mileage-independent LC phases, that are materials and production, while on the right side the contribution of use stage in function of LC mileage is illustrated. The range of operation distance taken into account is 0-250000 km.
