Rio Tinto

Rio Tinto is a global mining and materials company founded in 1873, with operations spanning 34 countries across six continents. Headquartered in London and Melbourne, the company extracts and processes iron ore, copper, aluminium, and lithium - resources that require extensive fleets of heavy diesel-powered equipment including haul trucks, excavators, loaders, and drill rigs across some of the most remote mining sites on earth.

With more than 61,000 employees worldwide, Rio Tinto maintains one of the largest heavy-equipment fleets in the mining industry. The company operates open-pit and underground mines, processing facilities, rail networks, and port infrastructure, all of which depend on large-scale diesel-powered machinery for daily operations. Its geographic footprint covers major mining regions in Australia, North America, South America, and beyond.

Rio Tinto has set targets to reduce emissions by 50% by 2030 and reach net zero by 2050. This transition includes exploring alternatives to conventional diesel in its mobile equipment fleet, making it a site where diesel technicians encounter both established heavy-machinery platforms and emerging lower-emission technologies. The company's stated purpose is "Finding better ways," reflecting an emphasis on operational innovation across its mining and materials operations.
