Lithium
The biggest current lithium producer is Australia, and there are fair amounts in China and parts of Europe, including the UK which has some high-grade deposits. Companies like Cornish Lithium are looking into extracting it.
However, over half of known lithium reserves are located in the 'lithium triangle' which spans Chile, Argentina and Bolivia. It is mostly in brine located in underground reservoirs below salt flats, from which it is extracted by pumping up the brine and evaporating off the water. This affects the water balance, and it is already a very arid area. Some local indigenous groups have protested, saying that it is affecting their water supply.
A number of technological solutions have been proposed, including improving or changing extraction methods. How well they work remains to be seen, but a lot of the problems are political, as companies are just not consulting with or compensating affected people. As Luisa Jorge, an activist in Susques, Argentina, said:
“lithium companies are taking millions of dollars from our lands … they ought to give something back. But they’re not.”
When it comes to processing of lithium and lithium-ion battery cells, a new report by Anti-Slavery International and partners says the percentage processed in the Uyghur Region, where there is systematic persecution by the Chinese government, continues to grow. Their guidance document for investors and policy brief to the UK Government says “it is imperative for governments and investors to divest from the Uyghur Region and diversify sourcing locations to ensure both an ethical and stable source of inputs for solar and EV technologies.”
What can you do about lithium sourcing?
The Anti-Slavery International report encourages consumers to use their bargaining power with companies that sell electric vehicles and solar panels to ask questions about their supply chains and links to the Uyghur Region before making a purchase.
Cobalt
70% of the world’s cobalt comes from the Democratic Republic of Congo (DRC). It isn’t associated with armed groups there like the other 'conflict minerals' we've heard so much about, but about a fifth of it comes from small artisanal mines where cobalt is dug from hazardous hand dug tunnels, often with no protective equipment and sometimes by young children. The miners are a mixture of waged labourers and people digging to sell the cobalt themselves. The DRC is one of the poorest countries in the world and a valuable mineral is an alluring prospect.
Some companies have tried to stop purchasing from these mines, and to just buy from the industrial mining operations which are regulated and don’t suffer from the same issues. However, as this threatens the livelihoods of those who depend on them, campaigners have urged companies instead to try to improve conditions, through initiatives like the Fair Cobalt Alliance, which Tesla has joined, and the Responsible Cobalt Initiative (RCI).
A lawsuit was filed in the US, in 2019, against several tech companies including Tesla, arguing that they have allowed dangerous forms of child labour to prosper in their cobalt supply chains. It was dismissed, but an appeal has been lodged.
Aluminium
Car manufacturers use 18% of all aluminium consumed worldwide, and more than half of it is primary aluminium produced from bauxite (as opposed to recycled). The biggest bauxite deposits are in Guinea (West Africa). Australia is the biggest producer, and mining has been associated with land and water grabbing in both countries.
Volkswagen, BMW, and Daimler have joined a certification scheme, the Aluminium Stewardship Initiative (ASI), formed in 2015, that audits mines, refineries, and smelters. Other companies should be encouraged to join.
