Objectifs et frontières du système
Unité fonctionnelle: 
Transportation of persons in a vehicle, for a total distance of 150 000 km (~93 000 miles), during 10 years, in compliance with type approval regulation over New European Drinving Cycle
Objectifs, hypothèses et limites: 
The goal of Renault’s LCA studies is to assess the environmental impacts of all new vehicles. When it exists, the goal of LCA studies is to compare the new vehicle with its predecessor. In this study they evaluate the environmental performances of new Renault KADJAR and make comparison between SCENIC 3 and new KADJAR. This comparison is based on the consumer targeted by vehicule, not just on the comparison of new vehicles because KADJAR and SCENIC share the same target in term of customers (family,young people) and propose the same kind of performances (weight, habitability, number of passengers) despite their opposite design. For making comparison, they use the same engine for both and define 5 environmental impacts to measure. Also, results of comparison are calculated by using the same database and the same version. During the comparison, they examine material composition, plants and logistics of these two vehicles. In material composition they consider metals, polymers, elastomers, glass and ceramic, fluids, organic material and others. And also, they consider that these two vehicles are not assembled in the same factory, SCENIC is assembled in France and KADJAR in Spain. Because of that they take into consideration their process of plants and logistics.

In the end of the LCA, the analysis of each of 5 environmental impacts shows us an improvement on KADJAR compared to SCENIC 3. It means KADJAR has a lower environmental footprint than SCENIC. If we look at particularly repartition of environmental impact of KADJAR along its life cycle, it shows us to in producing phase KADJAR has more acidification potential than other phases (use phase and end of life). And in using phase it has more abiotic depletion potential, global warmig potential, eutrophication potential and photochemical ozone creation potential than other phases. Also, before starting LCA, they determine 2 different recycling scenario. One includes 85 % of re-use and recycling and other includes 95 % of re-use,recycling and recovery. With the second scenario, they examine that they can decrease all of these potential effects.
If we go back at the comparison between SCENIC 3 and KADJAR, the difference between them is comprised for each environmental impact between 14 and 18%. The main difference for each impact concerns the production phase but the use phase has most environmental impact for each of the cars. For the use phase, the production of
fuel is the most significant for all the impact excepting for the global warming which is composed mainly with the driving phase.
