World’s biggest miner BHP backtracks on climate action with key projects put on ice, leaked documents reveal | Climate crisis
BHP, the world’s largest mining company, has significantly altered its decarbonization trajectory, according to internal documents. The company has delayed or abandoned key climate projects in Western Australia’s Pilbara region, pushing meaningful capital investment in renewable energy and emission-reduction infrastructure into the next two decades.
The internal records, dubbed the “BHP files,” indicate that the company previously acknowledged that failing to meet its public climate commitments posed a “reputational risk” and threatened its “licence to operate.” Despite this, the company has scaled back its decarbonization spending, citing technological limitations and a lack of readiness in heavy-duty electric vehicle equipment.
Project Delays and Strategic Shifts
The leaked documents reveal that several high-profile initiatives have been shelved or indefinitely postponed. A 50-megawatt solar farm and 20MW battery project at the Jimblebar mine, which had already received board approval and funding in 2023, was effectively canceled. Internal staff reports noted dissatisfaction with the decision to unilaterally halt a board-sanctioned project.

a substantial renewable energy system—comprising nearly 500MW of solar, wind, and battery storage—has been delayed. Originally intended to provide power by December 2027, the project now lacks capital funding until at least 2031. BHP has confirmed the project will not proceed in its current form.

The company also abandoned an iron ore processing plant designed to reduce annual emissions by 1.7 million tonnes. Despite the project being described as “well-aligned” with the company’s climate transition action plan, it was quietly removed from the development pipeline.
Implications for National Targets
Environmental analysts warn that BHP’s pivot could compromise Australia’s national climate goals, which include a 43% reduction in emissions below 2005 levels by 2030. Critics argue that as the nation’s largest company, BHP’s internal policy reversals carry significant weight, potentially setting a precedent for the wider mining industry.
BHP maintains that it remains committed to its net-zero 2050 goal and points to a 36% reduction in emissions from 2020 levels as evidence of its progress. The company contends that it is waiting for technological maturity in battery-electric haulage, noting that current equipment is not yet capable of handling the scale and complexity of Pilbara operations.
Future Outlook
Looking ahead, the company’s internal memo from May 2025 suggests that electrification of its truck and rail fleets could be pushed back to 2035 or 2040. If technological advancements in the mining sector continue to lag, BHP may further defer these investments or maintain its reliance on diesel power for an extended period.
Analysts expect that the company’s decision-making process will face continued scrutiny from shareholders who have previously signaled strong support for accelerated climate action. The path forward may depend on whether BHP accelerates trials of low-emissions technology or continues to prioritize conventional diesel-based infrastructure as a hedge against current technological uncertainties.
Frequently Asked Questions
What is the current status of BHP’s renewable energy projects in the Pilbara?
Major projects, including a 500MW solar, wind, and battery system, have been significantly delayed or canceled. The company has stated these projects will not proceed in their current form and has allocated no capital funding to them until at least 2031.
Why is BHP delaying the transition to electric mining trucks?
The company states that the technology for 240-ton battery-electric haul trucks is not yet advanced enough to be deployed at the scale required for its mining operations. It has continued to invest in diesel-powered fleets.
What are the potential risks of these delays?
Critics argue these delays could jeopardize Australia’s national emissions reduction targets. Internally, BHP documents acknowledge that these shifts pose a “reputational risk” and impact the “licence to operate” the company requires to function.
How should large-scale industrial firms balance their public climate commitments with the practical challenges of technological availability?
