Tom Graedel, Center for Industrial Ecology, Yale University, presents “The Periodic Table of Criticality and its Relationship to Product Design.” “Criticality” is the quality, state, or degree of being of the highest importance, and is of particular interest in the case of metals and other resources. A comprehensive methodology comprised of three dimensions – Supply Risk, Environmental Implications, and Vulnerability to Supply Restriction – has been created to quantify the degree of criticality of the metals of the periodic table. The methodology is designed to help corporate, national, and global stakeholders conduct risk evaluation and to inform resource utilization and strategic decision-making. It also has the potential to inform product design from a sustainability perspective, as will be illustrated and discussed.
