Contributing sentiments towards policy:

49% : The problem is that the greener process only works on high-quality iron ore, and most of BHP Group Ltd.'s iron ore comes from the Pilbara region in Western Australia, where the raw material contains too much phosphorus, alumina and other impurities to be refined using anything but coal.
48% : Most steel today is made in blast furnaces powered by coal, the dirtiest fossil fuel, but there's a way to refine the metal using less polluting natural gas or hydrogen in a process called the "direct reduced iron" (DRI) method, that reduces iron ore to iron without melting it.
