The Dark Side of Green: Cobalt Mining, Electric Vehicles, and the Human Cost of Energy Transition
A recent report, Toxic Transition, has brought renewed scrutiny to the cobalt supply chain, revealing allegations of hazardous emissions and community displacement linked to a large-scale mining operation in the Democratic Republic of Congo (DRC). This operation, the Tenke Fungurume mine owned by China’s CMOC Group, is a major source of cobalt – a critical mineral powering the electric vehicle (EV) revolution.
Communities at the Centre of the Supply Chain Debate
As automakers accelerate the shift away from fossil fuels, demand for cobalt has surged, with approximately 43% of global consumption now tied to electric vehicles. However, the communities where this mineral is extracted are bearing a disproportionate burden. The investigation, conducted by the Environmental Investigation Agency (EIA) and Congolese civil society group PremiCongo, focuses on the Tenke Fungurume mine, alleging the release of sulfur dioxide (SO₂) – a toxic gas linked to respiratory illness and environmental degradation.
“The health crisis is incredibly real,” says Alexander von Bismarck, executive director of the EIA. “Independent medical professionals say the connection to the mine is highly likely, and our own independent measurements show that the air in nearby communities has recently been above international safety standards.”
Global Automakers Drawn into Supply Chain Accountability Questions
The report, as cited by The Africa Report, traces cobalt from the Tenke Fungurume mine through battery manufacturers and into vehicles produced by major global brands, including BMW, Mercedes-Benz, Stellantis, and Volkswagen. While none of the companies have denied the potential for cobalt from the mine to indirectly enter their supply chains, responses have varied.
Mercedes-Benz has initiated discussions with the mine’s operator, while BMW stated it investigates potential supply chain violations. Stellantis confirmed sourcing cobalt from the mine and acknowledged previous reports of “serious illness linked to pollution” near the processing plant. Volkswagen had not responded to requests for comment at the time of publication.
Experts Challenge Supply Chain Complexity Claims
Despite claims of complex supply chains, EIA’s director, Alexander von Bismarck, dismisses the notion that tracing cobalt origins is technically difficult. He emphasizes that a majority of the world’s cobalt originates from this region of the DRC, with approximately 50% of global production coming from CMOC Group Limited. He argues that companies with substantial resources have a responsibility to ensure ethical sourcing.
“The companies either have to stop lying, stop claiming to be complying with human rights and environmental standards, or they must actually comply,” von Bismarck stated. The report calls for automakers to halt purchases of cobalt linked to emissions concerns at the Tenke Fungurume mine until the operation demonstrates compliance with Congolese law and international environmental standards.
Africa Pays the Price in Global Race for Critical Minerals
The situation in the DRC highlights a broader trend: as global demand for critical minerals grows, African countries are becoming key players in the United States–China rivalry. However, African communities often bear the environmental and social costs of mining. Experts emphasize the urgent need for stronger accountability, fair compensation, and protection for affected communities to ensure that Africa’s resources benefit everyone, rather than exacerbating inequality.
Similar concerns have surfaced across Africa, from copper operations in Zambia to bauxite mining in Guinea and lithium projects in Zimbabwe, where Chinese-owned mining companies have faced accusations of environmental damage, unsafe working conditions, and community displacement.
Future Trends and Potential Solutions
The challenges highlighted by the report are likely to intensify as demand for critical minerals continues to rise. Several trends are emerging that could shape the future of responsible mineral sourcing:
- Increased Transparency: Greater pressure on companies to disclose their supply chains and demonstrate due diligence.
- Technological Solutions: Development of blockchain and other technologies to track minerals from mine to market.
- Diversification of Supply: Exploration of new cobalt sources in other regions, such as North America and Australia.
- Recycling Initiatives: Investment in battery recycling technologies to recover cobalt and other valuable materials.
- Strengthened Regulations: Implementation of stricter environmental and labor standards in mining regions.
