Growing demand for electric vehicles is important to help cut transport emissions, but it will also lead to new mining. Without a careful approach, we could create new environmental damage while trying to solve an environmental problem. Like solar panels, wind turbines and battery storage technologies, electric vehicles require a complex mix of metals, many of which have only been previously mined in small amounts. These include cobalt, nickel and lithium for batteries used for electric vehicles and s…
