Carmakers' battery nickel linked to Indonesian deforestation

An analysis has linked the supply chains of Volkswagen, Ford, and Tesla to the deforestation of primary rainforest in Indonesia. The nickel mining operations are located on lands inhabited by the indigenous Tolaki people. The metal is a key component in the batteries used for the companies' electric vehicles.

The investigation traced nickel ore from the Cahaya and Hengjaya mines through regional smelters to Chinese processing plants run by Zhejiang Huayou Cobalt. This cathode manufacturer supplies both CATL, the world’s largest battery maker, and the South Korean group LG. Both firms are known to provide battery products to western carmakers.

The connection complicates the environmental branding of electric vehicles, tying their production directly to the destruction of indigenous woodlands for essential raw materials.
