Critical Materials

Project Blue’s Critical Material Risk Index (CMRI) 2022 provides a criticality ranking for 40 metals and minerals based on a CMRI score. Click on the name of a material to understand more about its CMRI score, or sort the table by “supply risk”, “ESG risk” and “economic importance” components to see how the 40 materials rank and compare.
