Study Confirms Aluminum Generates Lowest Total Carbon Footprint vs. Steel
The Aluminum Association’s Aluminum Transportation Group recently released an all-new, critically reviewed life cycle assessment (LCA) study confirming that automotive aluminum generates the lowest total carbon footprint. The LCA examines cradle-to-grave environmental footprint reductions of an advanced aluminum pickup truck body design in comparison with a baseline design using high-strength steel (HSS) and advanced high-strength steel (AHSS). The study confirms the aluminum body offers the potential to lower a vehicle’s life cycle global warming potential and primary energy demand by 7.8 metric tons of CO2 equivalent and 110 gigajoules, respectively. This is equivalent to total energy savings of nearly 11 million barrels of oil over the lifetime of a 600,000-unit vehicle production fleet.
Note that only design elements considered to be practical based on both technical feasibility and cost efficiency were used, and that extensive CAE (computer aided engineering) simulations were used to ensure appropriate crashworthiness, stiffness and strength.
