Amazon taps Rio Tinto’s low-carbon “Nuton” copper for AWS data centers as AI buildout bites
Rio Tinto and Amazon Web Services signed a two-year agreement for AWS to use “low-carbon” copper, produced with Rio’s Nuton bioleaching technology, in U.S. data centers. The copper, sourced from Gunnison Copper’s Johnson Camp mine in Arizona, has a reported carbon footprint of 2.82 kg CO2 per kg. AWS will also provide cloud analytics to optimize mining. Planned output is 30,000 tonnes over four years.
