yales method for metals=
this method consist out of 3 dimensions; supply risk, vulnerability, and environmental implications. and is created to quantify the degree of criticality of the metals of the peroidic table. the methodology, a sustantial enhencement of the United states national research council template, is designed to help corporate, national and global stakeholders conduct risk evaluation and to inform resources utilization and strategic decision making. the methods considers life cycle impacts on human health and ecosystem health.
