 This study compares the CO2 emissions and additional costs of various decarbonized materials used in sheet for automotive industry applications using LCA and cost estimate research. It evaluates the pathways to decarbonize steel and alternative materials such as aluminum and reinforced polymer composites and calculates normalized global warming potential, NGWP, estimates assuming inputs from the current USA electricity grid and a hypothetical renewables based grid. The results indicate that, when applying technologies available today, decarbonized steel will remain competitive compared to aluminum and composites in the context of automotive sheet selection.
