About 30 pounds of cobalt go into each EV battery to boost performance and energy storage, which are key to luring consumers from dirtier gas cars. But today 70% of cobalt comes from the Democratic Republic of Congo, where an estimated 40,000 children as young as 6 work in dangerous mines. The mines also bring deforestation, habitat fragmentation and high carbon emissions from mining and refinery processes that rely heavily on fossil fuels to produce electricity and drive heavy machinery. Some sources say cobalt mining’s CO2 emissions could double by 2030.
