Fortier Testimony - Heat Map of Supply Risk for All 54 Commodities 2007-2018

Figure 3 Heat map displaying supply risk for all 54 commodities examined for years 2007–2018. Warmer (i.e., orange to red) shades indicate a greater degree of supply risk. Commodities are listed in descending order of their 2015–2018 recency-weighted mean supply risk, as described in Nassar and Fortier, 2021. As indicated by the dashed horizontal line, 36 commodities with a recency-weighted mean supply risk greater than or equal to 0.40 were recommended for inclusion on the list of critical minerals based on quantitative criteria. Leading producing countries were based on cumulative production for the entire period of analysis for the different stages of production or commodity forms, where applicable.
