Analysis links carmakers’ nickel supply chains to Indonesian deforestation

The Guardian reports possible battery links to mines in indigenous woodlands, but the extract does not establish product-level traceability.

The Guardian reports an analysis linking mines in western carmakers’ supply chains to deforestation of primary rainforest in Indonesia’s nickel-rich lands inhabited by Tolaki people. Volkswagen, Ford and Tesla are named among manufacturers whose batteries may contain nickel mined in the affected woodlands. The wording describes a possible material link, rather than confirmed contents of particular batteries.

What holds up

  • ✓The report identifies Indonesia and lands inhabited by Tolaki people as the focus of the analysis.
  • ✓Volkswagen, Ford and Tesla are explicitly named, with the battery-content claim qualified as ‘may contain’.

What doesn't yet

  • ?The extract does not provide the analysis’s methods, mine-level evidence or chain-of-custody records.
  • ?No quantified forest loss or responses from the named carmakers are included.

Ask before you share

  • →Can nickel be traced from the identified mines to specific suppliers and batteries?
  • →How was forest loss measured and attributed to mining?
  • →What do the companies say about the findings and their sourcing controls?
