Greening the Mining Industry

An Australian regulator recently told Peabody Energy Glencore they couldn’t export coal from a new mine to countries that haven’t signed the Paris climate agreement. Two other Australian coal projects were scuttled in 2019, partly out of concern about greenhouse-gas emissions overseas.  Investors, too, are growing inquisitive about miners’ records on their customer emissions—partly out of fear about potential liability. Miners are responding by increasing carbon-impact disclosure, forming alliances with buyers and investing in technology to cut emissions from steel mills and power plants.  BHP  has said its scope 3 emissions—pollution mostly created when customers transport and use the commodities it produces—are almost 40 times greater than those generated at its own operations.

In the oil industry, facing similar pressures, there is friction among large companies over whether to commit to reducing greenhouse-gas emissions from products such as gasoline—in big part because emissions vary hugely depending on the vehicle…

Threats to miners’ business go beyond pushback on new projects. Consumer brands could stop buying commodities they consider too dirty, experts say. Many are already innovating with recycled materials.

In July 2019, BHP pledged to spend $400 million over five years to develop technologies that can reduce emissions both from its operations and its customers’.  “We won’t stop at the mine gate,” BHP Chief Executive Andrew Mackenzie said. …Rio Tinto is also drawing up scenarios for decarbonizing the steel industry. Success could materially affect the value of its core iron-ore business, it said.  Meantime, miners are touting their role in the shift to a low-carbon economy by producing commodities such as copper and nickel for wind turbines and electric vehicles.
