Vehicle LCA Study

The objective of this study is to benchmark, in terms of their life cycle greenhouse gas (GHG) emissions, vehicle body-in-white designs based on advanced high-strength steels (AHSS), like ULSAB-AVC, as well as aluminium, compared to designs based on mild steel. For this purpose a parametric spreadsheet model has been developed which calculates life cycle GHG emissions attributable to vehicles. Using this model, comparisons were made as to the GHG emissions produced over a vehicle life cycle. A key finding of the study states that based on an attributional LCA and current data uncertainty, there is no conclusive evidence that aluminium-intensive vehicle designs offer any GHG emission savings relative to AHSS-intensive designs like ULSAB-AVC.
