Electric vehicles are essential for reducing transportation emissions, but their production raises significant human rights concerns, particularly regarding mineral extraction. Amnesty International’s recent assessment of 13 automakers revealed substantial inconsistencies in their adherence to human rights standards, with Mercedes-Benz and Tesla performing best. Issues like child labor in cobalt mining and the treatment of indigenous communities were highlighted. However, initiatives like the upcoming “battery passport” aim to improve transparency, while alternative battery technologies and smaller vehicle designs may mitigate environmental impacts.
Electric Cars and Human Rights: A Complex Relationship
The scientific community largely agrees that electric vehicles (EVs) play a crucial role in reducing emissions within the transportation sector. However, sustainable development extends beyond mere environmental concerns; it also encompasses the safeguarding of human rights. This aspect becomes particularly critical when we examine the mineral extraction processes that supply the batteries used in electric cars.
Amnesty International’s Findings on Electric Vehicle Manufacturers
In light of these complexities, Amnesty International has undertaken an investigation into the practices of various car manufacturers. Following a concerning report in 2017, the organization has released a new assessment of 13 automotive brands, evaluating their advancements and compliance with human rights standards. The results reveal significant disparities among these manufacturers, with Mercedes-Benz and Tesla leading the charge, while BYD lags behind.
Amnesty International’s review focused on the sourcing practices for key battery components such as cobalt, copper, lithium, and nickel. The brands scrutinized include BMW, BYD, Ford, Geely, GM, Hyundai, Mercedes-Benz, Stellantis, Renault, Nissan, Mitsubishi, Tesla, and Volkswagen. By analyzing corporate social responsibility (CSR) reports and the responses from these companies, Amnesty established a set of categories to evaluate their efforts regarding human rights. Key areas assessed included risk identification, prevention measures, monitoring, and reporting practices.
The overall outcomes were disappointing, with the highest-scoring brand achieving only 51 out of a possible 90 points. Mercedes-Benz led the pack, closely followed by Tesla with 49 points. In stark contrast, BYD received a mere 11 points due to a lack of transparency, while Mitsubishi managed to score only 13 points.
Amnesty International raised alarms about several critical issues, notably the alarming conditions in the Democratic Republic of Congo (DRC), the source of approximately 70% of the world’s cobalt supply. Reports of child labor in cobalt mines have drawn significant concern, as the health and environmental risks associated with mining practices remain high.
Moreover, the treatment of indigenous communities continues to be a pressing concern, with Amnesty highlighting the disregard for their rights and preferences in mining operations. The organization also pointed to human rights issues in countries that supply lithium, including Bolivia, Argentina, Chile, Indonesia, and the Philippines.
Despite the concerning landscape, there are signs of progress. The latest report indicates improvements since the near-total lack of mineral traceability in 2017. Amnesty acknowledged that many manufacturers have begun to recognize their responsibilities regarding human rights and align their policies with international standards, but emphasized that much work remains to be done.
Looking ahead, the introduction of the “battery passport” by the European Commission, effective January 1, 2026, aims to enhance transparency in the electric vehicle market. This initiative will require manufacturers to disclose their battery component suppliers, a practice already adopted by brands like Volvo.
Furthermore, the trend towards alternative battery chemistries, such as lithium-iron-phosphate (LFP), is gaining traction. These alternatives, favored for their cost-effectiveness, do not rely on cobalt or nickel, which pose significant ethical and environmental challenges. Innovations in sodium batteries also hold potential for the future, particularly for smaller electric vehicles and energy storage solutions.
Another strategy to mitigate the environmental impact of electric vehicles is by reducing demand for minerals. Current projections suggest that the need for these materials could increase ninefold from 2024 to 2050. Although recycling offers a promising approach, the extended lifespan of batteries, coupled with the relatively low number of electric vehicles currently in use, limits its effectiveness.
A more critical consideration is the reduction of battery sizes. A 2023 WWF study indicates that if battery capacities continue to trend towards 100 kWh, production may not keep pace with demand. Thus, a shift towards smaller, more efficient vehicles, similar to Japanese kei cars, could offer a sustainable solution. Compact batteries not only reduce ecological impact but also lower costs for consumers, representing a balanced approach to the future of electric transportation.
