4 Model assumptions and findings of the Life Cycle Assessment Data basis • <strong>Volkswagen</strong> vehicle parts lists • Material and weight information from the <strong>Volkswagen</strong> Material Information System (MISS) • Technical data sheets • Technical drawings • Emission limits (for regulated emissions) laid down in current EU legislation • The data used comes from the GaBi database or was collected in cooperation with VW plants, suppliers or industrial partners Life Cycle Inventory results • Material compositions in accordance with VDA (German Association of the Automotive Industry) Standard 231-106 • Life Cycle Inventory results include emissions of CO2, CO, SO2, NOX, NMVOC, CH4, as well as consumption of energy resources • The impact assessment includes the environmental impact categories eutrophication potential, ozone depletion potential, photochemical ozone creation potential, global warming potential for a reference period of 100 years and acidification potential • Standardisation of the results to average impact per inhabitant values Software • Life Cycle Assessment software GaBi, and GaBi DfX Tool and VW slimLCI interface as support tools Evaluation 20 • Evaluation of Life Cycle Inventory and impact assessment results, subdivided into life cycle phases and individual processes • Comparisons of impact assessment results of the vehicles compared • Interpretation of results
5 Results of the Life Cycle Assessment Results of the Life Cycle Assessment Material composition Fig. 8 shows the material composition of a Golf VI 2.0 TDI in accordance with the VDA (German Association of the Automotive Industry) standard 231-106 for material classification [VDA 1997]. 16 The graph indicates the material composition of and material shares in the vehicle assessed. Fig. 8: Material composition of Golf VI 2.0 TDI DPF Material composition Golf VI 2.0 TDI DPF* 65 % The Golf VI 2.0 TDI consists of 65 percent steel and iron materials and 17 percent various plastics (polymer materials). It also contains about six percent light alloys, such as aluminium and magnesium. Nonferrous metals, such as copper and brass, account for about three percent of the car‘s materials. The composite and other materials, which account for approximately three percent of the vehicle by weight, include ceramics and glass, renewable raw materials and materials which are inseparably joined, e.g. metal coated with plastic. Operating fluids, such as oils, fuel, brake fluid, coolant and washing water combined, account for about five percent of the total vehicle weight. The remaining approximately one percent is made up of process polymers such as paints and adhesives. The share of electronics and electrics is extremely low because the materials used in these components have been itemised in detail on the basis of the 16 Unladen weight in accordance with DIN 70020 without driver and with the fuel tank filled to 90% of capacity. 21 Steel and iron materials Light alloys, cast and wrought alloys Nonferrous heavy metals, cast and wrought alloys Special metals Polymer materials Process polymers Other materials and composite materials Electronics and electrics Fuels and auxiliary materials 6 % 3 % 0.05 % 1 % 3 % 0.01 % 5 % 17 % * Diesel particulate filter
