The Steel Recycling Institute (SRI), a business unit of the American Iron and Steel Institute, released a peer-reviewed study demonstrating the importance of material production emissions toward a vehicle’s lifetime environmental impact. The study, “Life Cycle Greenhouse Gas and Energy Study of Automotive Lightweighting,” examines the overall environmental impact of vehicle lightweighting using advanced high-strength steel (AHSS) compared with aluminum. It concludes AHSS-intensive vehicles had lower or equivalent life cycle emissions than aluminum-intensive vehicles for every class of vehicles tested – sedans, trucks, SUVs and alternative power train vehicles. The study was independently reviewed by expert representatives from Harvard, Massachusetts Institute of Technology, Argonne National Lab, and thinkstep to establish conformance with International Organization for Standardization (ISO), the globally recognized benchmark for standard setting.
