The Democratic Republic of Congo is the major source of some of the minerals used to manufacture components in household appliances, mobile phones, electric vehicles and jewellery.
The mineral extraction industry is the backbone of the Congolese economy. Copper and cobalt, which is a by-product of copper, accounts for 85% of the country’s exports. Because of the huge mineral deposits available in the country, it is often the only sourcing option for companies.
Cobalt is an essential mineral for the lithium-ion batteries used in electric vehicles, laptops and smart phones. It offers the highest energy density and is key for boosting battery life.
The Katanga region in the south of the Democratic Republic of Congo is home to more than half of the world’s cobalt resources, and over 70% of the current cobalt production worldwide takes place in the country. Demand for cobalt is projected to surge fourfold by 2030 in pace with the electric vehicle boom.
However, mining in the Democratic Republic of Congo is risky because of the prevalence of artisanal small-scale mining. Artisanal mining is often carried out by hand, using basic equipment. It’s a largely informal and labour-intensive activity on which more than two million Congolese miners depend for income.
And this mining method comes with major human rights risks such as child labour and dangerous working conditions. Fatal accidents in unsafe tunnels occur frequently. And there are detailed reports such as the one by Amnesty International on the prevalence of child labour in these operations.
Because artisanal miners frequently extract cobalt illegally on industrial mining sites, human rights issues cannot be excluded from industrial production. Artisanally mined cobalt also often gets mixed with the industrial production when it is sold to intermediaries in the open market. Typically, it is then shipped to refineries in China for further processing and then sold to battery manufacturers around the world. In this complex supply chain, separating, tracking and tracing artisanally mined cobalt is almost impossible.
International human rights organisations have flagged human rights abuses, putting pressure on multinational corporations that buy Congolese cobalt. In response to these pressures, some automotive and electronics companies are currently not sourcing cobalt from the Democratic Republic of the Congo because they want to avoid tainting their brand image.
But that strategy won’t work for long, as no other country will be able to satisfy the rising demand for cobalt. The production of other cobalt-exporting countries such as Russia, Canada, Australia and the Philippines accounts for less than 5% of the global production.
How companies in the cobalt supply chain can source responsible cobalt from the Democratic Republic of the Congo amid these human rights risks is a question worth exploring. We address this question in a recent study, in which we suggest companies should acknowledge the need for common standards for responsibly mined cobalt.
Currently, there is no common understanding of what “responsible” artisanal cobalt should entail. The quest for responsible mineral sourcing is not a cobalt-specific challenge. The Congolese mining code establishes certain basic standards such as the prohibition of miners under the age of 18. There are also requirements to register as an artisanal miner and become a member of a mining cooperative.
One approach towards common standards is to mount “artisanal and small-scale mining formalisation projects”. The few existing projects establish rules for the mining site that are defined and enforced by the project partners. These usually consist of cooperatives, mine operators and buyers.
One of us visited two active formalisation projects in Kolwezi in Katanga province. Based on the observations during the September 2019 visit, we believe that formalisation is a viable path to making artisanal mining safe and fair.
Formalisation works because operational measures are put in place to mitigate safety risks. For example, the extraction is supervised by mining engineers. Also, the project site is fenced off and has exit and entry controls. This ensures that no underage, pregnant or drunk miners can work on site.
But for formalisation projects to yield “responsible” artisanal cobalt, common standards and consistent enforcement are necessary. Currently, formalisation means different things in different sites.
National standards for mine safety exist, but they need to be enforced uniformly. Where current standards fall short of reassuring buyers, further measures need to be developed by a consortium of the key players. This should involve mining cooperatives, concession holders, the government, civil society organisations, and other companies along the battery supply chain.
The 2018 amendments to the mining code introduced a legal basis for the subcontracting of artisanal miners by industrial mining companies. In January 2020, the Congolese government created an entity that will oversee artisanal and small-scale mining activities. These are positive steps.
The development of artisanal mining standards through a process involving key players needs to build on and strengthen these existing national laws and strategies. Furthermore, private actors should support government efforts by identifying parameters and means of evaluation to ensure the consistent enforcement of these standards. A discussion about responsible sourcing strategies and practices is indispensable for all brands that care about the human rights implications of their operations.
The way forward
To illustrate how a multi-stakeholder discussion over responsible sourcing standards translates into practice, we can examine tunnel construction to extract the ores underground at artisanal and small-scale mining sites.
The first issue is whether tunnels should be allowed at all or whether responsible artisanal cobalt should take place exclusively from open pits. Open pits are considered significantly safer. If only open pits are considered responsible, who will pay for the earth-moving machines needed to create open pits?
If tunnels are allowed, how deep can they be? While relevant mining regulations limit tunnel depth to 30 metres and tunnel inclination to 15%, international buyers of cobalt do not consider this safe.
Given that horizontal tunnel construction is particularly dangerous, should horizontal tunnels be banned entirely from sites? If tunnels are permitted, should miners receive training on construction safety, and if so, who will pay for these programmes?
These processes and regulations must be standardised and widely adopted. Only when this happens will automotive and electronics companies be reassured that they are not contributing to human rights violations. And only then will they feel confident buying Congolese cobalt.
Responsible sourcing of cobalt from the DRC is a fully independent research project. The travel cost of the field research in the DRC were reimbursed by the World Economic Forum's Global Battery Alliance. All other funding for this research came from the University of Geneva, where I direct the Geneva Center for Business and Human Rights, and from the NYU Stern School of Business, where I am research director of the NYU Stern Center for Business and Human Rights.
Our Center has received funding from the World Economic Forum's Global Battery Alliance solely for the travel expenses related to the research trip to the DRC. I am a consultant at the Geneva Center for Business and Human Rights at the University of Geneva.
