A new study has been released claiming that there are human rights violations occurring in the supply chain process that provides materials for electric vehicles in the United states.

As Just The News reports, the report released by Amnesty International is titled “Recharge for Rights.” The study focuses on human rights violations that have been committed in the name of mining and trading the minerals that are necessary to power up electric vehicles (EVs). These include child labor, slavery, forced evictions, and health impacts from pollution.

“The human rights abuses tied to the extraction of energy transition minerals are alarming and pervasive and the industry’s response is sorely lacking” said Agnès Callamard, Secretary General of Amnesty International, in a statement.

Amnesty International noted that all EV manufacturers are complicit in this process, although American companies such as Tesla did the most to respect human rights during their manufacturing process; the company with the highest score in preserving human rights is Mercedes-Benz. Meanwhile, the worst offenders included Chinese automakers BYD and Greely Auto, Japanese companies Mitsubishi and Nissan, and the South Korean brand Hyundai.

The report follows a similar report issued last month by the U.S. Department of Labor (DOL) titled “List of Goods Produced by Child Labor or Forced Labor,” which documents the human rights violations in the processes of mining such materials as cobalt, lithium, nickel, and other minerals.

A major reason for the human rights violations in these mining processes is the host countries that are the richest in such materials. Many of the materials necessary for EV manufacturing are found in China, which has very few laws on human rights. By employing slave labor and child labor, as well as ignoring environmental regulations, China can keep the cost of producing such minerals relatively low for maximum profit when selling them.
