Rio Tinto has successfully completed the full transition of its heavy machinery from fossil diesel to renewable diesel at its Boron, California operation, making it the first open pit mine in the world to achieve this milestone. The change to renewable diesel brings an anticipated CO₂ equivalent reduction of up to 45,000 tonnes per year, comparable to eliminating the annual emissions of approximately 9,600 cars.
