Electric vehicle batteries from major carmakers like Volkswagen, Ford, and Tesla have been linked to destructive deforestation in Indonesia, according to a recent analysis. The investigation reveals that nickel mining for these batteries is causing widespread environmental damage in Sulawesi, a biodiversity hotspot and home to the indigenous Tolaki people.
The Link Between EV Batteries and Deforestation
Nickel is a key component in EV batteries, as it boosts energy density and extends driving range. However, the mining of this metal in Indonesia's Sulawesi region has led to significant deforestation of primary rainforests. Satellite analysis shows that mines such as Cahaya and Hengjaya have cleared thousands of hectares of indigenous woodlands.
The ore from these mines is processed through regional smelters and Chinese plants operated by Zhejiang Huayou Cobalt, a major cathode manufacturer. Huayou supplies CATL, the world's largest battery maker, which in turn provides batteries to numerous automakers. Corporate disclosures and trade data indicate that Volkswagen, Ford, and Tesla are among the end-users of these batteries.
Impact on Indigenous Communities
The deforestation has severely affected the Tolaki people, who have inhabited these lands for generations. "We used to ask the forest for protection in return for our offerings," said Wadimula, a Tolaki elder. "Now the forest is gone, and we are left with polluted water and air." The loss of forests also threatens wildlife, including rare species found only in Sulawesi.
Supply Chain Complexity and Corporate Responsibility
Tracing the supply chain from mine to car is challenging due to the involvement of multiple intermediaries. The analysis found two main routes: one from Huayou to CATL, and another from Huayou to LG, a South Korean company that supplies battery products to leading carmakers via Poland.

Automakers have pledged to source materials responsibly, but this investigation highlights the difficulties in ensuring truly sustainable supply chains. While some companies have made efforts to audit their suppliers, the rapid expansion of nickel mining in Indonesia outpaces these efforts.
Comparison of Automakers' Responses
| Automaker | Response |
|---|---|
| Volkswagen | Stated commitment to responsible sourcing; investigating the claims. |
| Ford | Acknowledged the issue; working with suppliers to improve traceability. |
| Tesla | Emphasized its goal for a sustainable supply chain; reviewing the findings. |
