Rio Tinto is rolling out a major internal shake-up as it looks to simplify operations and push more responsibility to its frontline mining businesses. The company, one of the world’s largest producers of iron ore, copper and aluminium, has been under pressure to improve productivity while still meeting climate commitments and managing volatile markets and energy supply risks. Its latest overhaul follows the recent end of merger discussions with another global miner, which adds to the sense that the group is refocusing on tighter management of its existing assets.
Under the new structure, Rio Tinto has dissolved its specialist decarbonisation unit and moved much of that work back into individual commodity divisions. The company has trimmed its decarbonisation project budget from about $US7.5 billion to a range of roughly $US1 billion to $US2 billion through to 2030. It is moving away from a large central program towards smaller efforts embedded within each business. Iron ore will now directly manage projects such as phasing out diesel haul trucks in the Pilbara in favour of battery-electric fleets, while the aluminium arm will take charge of re-powering east coast smelters with lower-carbon energy. A central technical team still oversees group-wide strategy, governance, investment review and climate reporting, but specialist roles have been cut or redeployed. Some partners only realised that changes had occurred when familiar contacts left or stopped responding.
In the broader context, Rio Tinto’s reset appears to be part of a wider industry trend where large miners rein in headline climate budgets, rely more on third-party renewable projects and push accountability into each commodity business. The company maintains that its long-term aim to roughly halve emissions by 2030 remains in place, but with reduced spending and more fragmented responsibilities there is greater uncertainty around how and when specific technologies, such as large-scale electrification and low-carbon power deals, will be delivered. Similar budget cuts at rival miners suggest that this approach could become the norm. This may slow the pace of heavy-industry decarbonisation even as pressure from governments, customers and investors continues to grow.
