Cobalt leads the index additionally as a result of its extraction is linked to ongoing social issues in Central Africa, which raises ESG considerations amongst battery makers because the metallic performs a key position in lithium-ion batteries, aerospace, and different crucial functions.
The Danger Index examines 40 crucial metals and minerals towards variables chosen to quantify provide danger, ESG danger, and financial significance. The info are normalized and weighted to provide three sub-indices that are then used to calculate a fabric’s general rank.
The second spot, proper after cobalt, is occupied by heavy uncommon earths equivalent to europium and dysprosium, that are principally refined in China with just one plant outdoors the Asian big situated in Malaysia. For that reason, REEs provide danger is definitely greater than that of cobalt however since their financial significance and ESG dangers are a bit bit decrease, they didn’t rank as excessive because the silver-grey metallic.
Since comparable circumstances apply to niobium and light rare earths, they occupy the third and fifth spots within the Index with very excessive provide dangers and decrease ESG-associated dangers, in addition to not so excessive financial significance.
In the midst of these is magnesium, a fabric wanted to harden aluminum alloys used to make cars and constructing provides. Supply risks, primarily linked to China and Russia being the most important world producers of the ingredient, place it within the fourth spot of the Danger Index.
Graphite, chromium, antimony, and vanadium full the highest 10, most of them scoring excessive because of the dangers related to their respective provide chains, with aluminum being the one outlier in its sixth spot and scoring excessive as a consequence of its financial significance.
“Whereas it’s no shock that cobalt, uncommon earths, and niobium high the worldwide listing, it’s necessary to do not forget that what makes a fabric crucial may be very a lot subjective, and relies on your place within the worth chain,” Jack Bedder, co-founder of Challenge Blue, mentioned in a media assertion.
