Chile-based Antofagasta is committed to mitigating and adapting to climate change, CEO Ivan Arriagada said this week, stating that the London-listed company was “well on track” to achieving its target of reducing its carbon dioxide emissions by 300 000 t by 2022. The copper miner is taking advantage of the price of renewable energy, which in Chile is cheaper than more polluting technologies, to decarbonise its electricity supply.
