Rio Tinto Chases Greener Identity In Australia And China

Rio Tinto is digging for ways to curb greenhouse gas emissions across mining and smelting operations ranging from Australia and the U.S. to China, the company's largest market.

The mining titan will spend about $750 million to expand iron ore operations in northwestern Australia's Pilbara region. Plans announced Wednesday include a 13 km conveyor belt from the mining pits to a processing facility, which will cut greenhouse gas emissions by 3.5% compared with moving the material by truck.

The Anglo-Australian company said it is assessing "additional options to reduce emissions including renewable energy solutions." Rio Tinto exited the coal business last year as it seeks a greater focus on materials like lithium, a core component for electric vehicles.
