Exploitation of Workers in DR Congo Taints Electric Vehicles

The acceleration of electrical vehicles (EV) production is crucial for the transition to a low-carbon economy, yet it appears to be linked to serious labour rights abuses. New research released today reveals dire conditions, discrimination and extremely low pay at some of the world’s largest industrial cobalt mines operated by multinational mining companies in the Democratic Republic of Congo. Cobalt is considered an essential mineral in the lithium-ion batteries that power electric vehicles. Over 70% of the world’s cobalt is extracted in Congo.

Cobalt is everywhere. It is a silvery-blue mineral used in the rechargeable batteries that power our mobile phones, laptops and tablets, and in larger quantities, the electric vehicles that will soon dominate our roads. It is a strategic mineral in the plan to decarbonise and move away from fossil fuels towards renewable energy. Accelerating this switch is one of the priorities to tackle the climate crisis and industry experts forecast that electric vehicle sales will skyrocket in the next 10 years. This will require a dramatic increase in cobalt production. The booming demand for cobalt has a dark side, however.

The 87-page report"The Road to Ruin? Electric vehicles and workers’ rights abuses at Congo’s industrial cobalt mines” by by corporate watchdog Rights and Accountability in Development (RAID), and Centre d’Aide Juridico-Judiciaire (CAJJ), a Congolese legal aid centre specialised in labour rights, exposes a system of widespread exploitation. Congolese workers at five industrial mines in Congo where cobalt is produced: Kamoto Copper Company (KCC), Metalkol RTR, Tenke Fungurume Mining (TFM), Sino-Congolaise des Mines (Sicomines) and Société Minière de Deziwa (Somidez) were interviewed for the research. They said they received very low pay and were subjected to excessive working hours, degrading treatment, violence, discrimination, racism, unsafe working conditions, and a disregard for even basic health provision.

Some workers described being kicked, slapped, beaten with sticks, insulted, shouted at, or pulled around by their ears. Others reported severe discrimination and abuse at Chinese-operated mines. One worker said, “Our situation is worse than before. The Chinese come and impose their standards and culture. They don’t treat Congolese well. This is new colonisation.”

Workers employed via subcontractors

The labour rights abuses are directly linked to an outsourcing model whereby workers are not hired directly by the mines, but instead are employed indirectly via subcontracting firms. Official figures show at least 57% of the workers employed across the five mines studied in the report are supplied by subcontractors. At some mines the percentage was significantly higher.Those interviewed for the report, including managers at subcontracting firms, said the multinational companies do so to reduce labour costs, to limit their legal liabilities and to prevent workers from joining unions.

Workers hired indirectly by the mines earn extremely low wages, often much less than the living wage of $402 per month, the minimum remuneration to afford a decent standard of living. They have limited healthcare benefits, sometimes as low as $10 per month, or none at all, even though Congolese law requires employers to provide free healthcare to workers and their dependents.

Many workers expressed despair that they were unable to pull themselves or their families out of poverty. One worker said, “We were working hard, without any breaks, for $2.5 a day. If you didn’t understand what the boss said to you, he would slap you in the face. If you had an accident, they would just fire you.”

They produce for General Motors, Renault, Tesla, Toyota, Volkswagen and Volvo

In their report, RAID and CAJJ trace the cobalt from the five mines through the supply chain to EV manufacturers such as General Motors, Renault Group, Tesla, Toyota, Volkswagen and Volvo, among others. These consumer-facing companies say they seek to source minerals responsibly. Although such commitments are much needed, none of the growing number of industry initiatives aimed at supply chains are binding and many do not cover workers’ exploitation or a broad range of labour rights.

What should be done

RAID and CAJJ called on all cobalt and copper mining companies operating in Congo to end the extensive use of subcontracting firms for their labour needs, to pay all Congolese workers (direct and indirect hires) the minimum living wage, and to immediately investigate and take action to address allegations of physical violence, racism and discrimination against Congolese workers. They called on car companies to end contracts with cobalt suppliers who failed to take action to remedy worker exploitation.

The organisations also urged for the implementation of robust measuresto create incentives for change and accountability along the cobalt supply chain, from governments adopting strong legal frameworks, such as mandatory human rights due diligence laws (requiring companies to address the adverse impacts of their operations on human rights and the environment) as well as stronger industry frameworks which cover workers’ rights.

The mines studied

The mines and their parent companies covered in the study include the following: (i) Glencore’s Kamoto Copper Company (KCC), (ii) Eurasian Resources Group’s Metalkol RTR, (iii) China Molybdenum’s Tenke Fungurume Mining (TFM), (iv) China Nonferrous Metal Mining Company (CNMC)’s Société minière de Deziwa (Somidez) of which the Congolese state company Gécaminesowns 49% and, (v) Sino-congolaise des mines (Sicomines), a joint venture between Gécaminesand a consortium of Chinese companies and investors.

RAID and CAJJ calculated that together these mines produced nearly half of the global cobalt supply in 2020.
