Critical and strategic materials are characterized by their importance in key applications and their vulnerability to supply chain disruptions. Much current research focuses on identifying and quantifying metrics and indicators that can predict potential supply chain risks for these materials. One area of criticality that has received considerably less attention is quantifying their substitutability, an important firm-level option for reducing risk. This research work uses a functional unit framework borrowed from life-cycle assessment methodologies to quantify metrics for substitution that can better capture functionality trade-offs. Several case study materials are examined from clean energy, defense, and electronics applications. Results indicate this approach has several advantages over current qualitative and semi-quantitative indicators and may be better equipped to inform firm-level research and development activities.
