Last month, Aborigen Forum, a group of Russian indigenous activists and leaders, launched a campaign to raise awareness of Norilsk Nickel’s impacts on their communities and to demand restitution. Rather than focus on an obscure Arctic mining company, Aborigen Forum is appealing to someone more likely to grab international headlines: Elon Musk, the CEO of Tesla. Nickel is a key ingredient in the cathodes of electric car batteries, allowing them to store more energy more cheaply. Tesla, and other EV makers, need lots of it. But Aborigen Forum wants Musk to commit that his company won’t buy any nickel that can be traced to Norilsk until the Russian megapolluter cleans up its act.
