Rio Tinto targets a fifty percent cut in operational emissions by 2030 and net zero by 2050, backed by up to six billion dollars in decarbonisation investment. The company grows production of copper, lithium, and high-quality iron ore to meet surging energy transition demand. Breakthrough projects like the Yarwun hydrogen calcination pilot and the Elysis carbon-free aluminium smelting venture demonstrate that Rio Tinto is pursuing genuine technological transformation, not just incremental improvement.
