The revelation that BHP cancelled and delayed commitments to act on the climate crisis should be a wake-up call.
It matters in its own right: millions of tonnes of additional heat-trapping pollution will go into the atmosphere, adding to climate harm and making Australia’s climate targets that much harder to reach.
It also matters for the influence the world’s biggest miner could have in accelerating use of technology needed to cut pollution from major industrial operations.
BHP is not alone among its peers in stepping back its climate action. Rio Tinto has slashed spending on projects to reduce emissions and disbanded its specialist decarbonisation unit. Other major corporations have either jumped in fear of Donald Trump or used his rise as an excuse to drop climate commitments.
But the scale of BHP’s reversal, revealed in documents leaked to the Guardian and the ABC, is significant.
It shelved the first big investment planned under its decarbonisation plan – a huge solar farm – after it was approved and funded by its board. A much larger solar, wind and battery development that would have run most of its inland operations in northern Western Australia has been delayed for at least five years.
BHP has also doubled down on using diesel-powered trucks, despite a promise to switch to a fleet of electric vehicles running on renewable energy. Internal documents acknowledge this is inconsistent with its climate pledges.
Making promises to cut emissions is the easy part. Designing and spending up on plans to achieve those cuts is a tougher exercise. Inevitably, there will be bumps on that road. But the leaked documents show that is not what has happened here. Instead, BHP has balked at commitments that a company of its heft and worth could prioritise if it chose.
The company’s own estimates suggest that its full decarbonisation could cost US$7.5bn over the next 25 years. It brings in the equivalent revenue in less than six months from its WA operations alone.
BHP is famously known as the Big Australian – a reflection of its success and scale since its origins mining silver and lead in Broken Hill 140 years ago. It remains at or near the top of lists of the country’s most profitable companies. In many ways, it is a responsible corporate citizen. It and Rio pay more tax in Australia than any other company.
But it is also a historic, global-scale polluter, mostly thanks to its mining of coal. Its extraction of that dirty fuel means it has been in the upper echelon of corporate emitters since industrialisation.
The thinktank InfluenceMap lists it as the 31st biggest cumulative contributor to the climate crisis, and the 10th biggest among companies owned by private investors.
Over the past 140 years, it has been responsible for more than 11bn tonnes of carbon dioxide pumped into the atmosphere, counting the pollution released when its customers use its products. That’s equivalent to about 25 years of Australia’s current annual emissions.
These days its marketing emphasises the need to cut emissions. It has sold some coalmines, and offloaded its petroleum arm – its oil and gas assets – to the Australian fossil fuel giant Woodside. It mines iron ore, copper, nickel and potash as well as metallurgical coal, used in steelmaking.
But selling coal, oil and gas assets doesn’t help the planet. Those businesses continue to operate in other hands. And the BHP files show the company is now a long way from where it was in 2019, when its then chief executive, Andrew Mackenzie, told an audience of the powerful in Britain that fossil fuel dependence was a potential existential threat.
The company says it is acting – that its emissions are down 36% since 2020, putting it ahead of its target of a 30% reduction by 2030. But the detail here matters. The claimed cut is due to power purchase agreements signed for some grid-connected renewable energy projects, particularly in Chile, and the 2024 suspension of its struggling Western Australian nickel operations.
Its direct onsite emissions, mostly from burning diesel, continue. And its annual report shows its scope-three emissions – those that result from the use of its products – have increased by 7% since the turn of the decade. The scale of that increase – more than 25m tonnes a year – dwarfs the reduction the company claims it has made.
There is a strong case, given the scale of its contribution to the problem, that BHP has a responsibility to invest heavily now to cut its emissions more rapidly than others and help accelerate solutions that could have a global impact.
One reason it hasn’t might be that the Australian Labor government is sending mixed messages to big miners even as it pledges the country will reach net zero emissions by 2050.
Mining companies receive more than $4bn a year in rebates on the cost of diesel that are not offered to households and small businesses. BHP is the biggest beneficiary. According to the thinktank Clean Energy Finance, the fuel tax credit scheme lowered its fuel bill by about $620m last year.
Making fossil fuels cheaper is a strange way to encourage the uptake of electric trucks running on renewable energy. It also works against the goals of a government policy that requires big industrial sites, including those operated by BHP, to cut emissions year-on-year.
That policy, the safeguard mechanism, also has an out. It allows companies to buy an unlimited number of carbon offsets instead of making direct cuts in pollution. And, for now at least, offsets are pretty cheap.
The BHP files show that the company could reduce its reliance on offsets, and it certainly doesn’t need the diesel rebate. Rather than have its fossil fuel use subsidised by Australian taxpayers, it needs policies that encourage it to actually live up to its rhetoric – and move much faster in the direction it has promised to go.
Four leading AI models discuss this article
"Avoiding multi-billion-dollar green capex while subsidies persist should support higher near-term free cash flow and shareholder returns."
BHP's cancellation of approved solar projects and five-year delay on a major WA renewables scheme, alongside sticking with diesel trucks, signals management prioritizing near-term cash preservation over 2019 rhetoric. With full decarbonization pegged at US$7.5bn over 25 years against six months of WA revenue, the moves could lift free cash flow and support buybacks or dividends. Scope 3 emissions rose 7% while claimed cuts rely on one-off nickel suspension and Chilean PPAs, not operational change. Persistent diesel rebates (~$620m last year) and cheap offsets under the safeguard mechanism further reduce urgency. Investors should watch whether this invites future regulatory tightening or ESG-driven valuation discounts.
The delays may simply reflect realistic reassessment of unproven electric haulage economics and grid constraints in remote WA rather than retreat, allowing BHP to meet 2030 targets via lower-cost offsets without sacrificing margins.
"BHP's climate commitments are credibility-damaged not by the math but by the gap between stated urgency and actual capex discipline, which signals either management doubt about ROI or external pressure (Trump, investor sentiment) overriding prior conviction."
BHP's climate backsliding is real and material, but the article conflates two separate issues: poor optics versus actual financial risk. Yes, shelving a solar farm and delaying renewable infrastructure after board approval looks hypocritical. But the company's Scope 1/2 emissions reductions (36% vs. 30% target) are genuine, even if accounting-dependent. The real issue is Scope 3 (product use) up 7%, which BHP cannot unilaterally solve—steel and coal demand are customer-driven. The article's strongest point: the $620m diesel rebate is taxpayer-funded anti-incentive. But it ignores that BHP faces genuine capex discipline post-inflation spike, and renewable infrastructure ROI in remote WA remains marginal. The company's decarbonization cost estimate ($7.5bn over 25 years) is trivial relative to cash flow, yet delays suggest either lower-than-stated conviction or regulatory/market uncertainty about payoff timing.
BHP may be rationally deferring capex not from cowardice but because renewable energy economics in remote mining regions remain unproven at scale; premature investment could destroy shareholder value without moving the climate needle if product demand doesn't shift.
"BHP's retreat from climate commitments is a defensive capital allocation strategy that creates long-term regulatory exposure to the Australian fuel tax credit scheme."
BHP is caught in a classic 'greenwashing' trap, but the market reaction is likely to be muted. While the leaked documents highlight a retreat from decarbonization, investors are currently prioritizing capital discipline and dividend yields over ESG optics. BHP’s decision to prioritize diesel trucks over expensive, unproven electrification at scale is a rational, if cynical, move to protect margins in a high-cost environment. However, the reliance on the Australian fuel tax credit—a $620m annual subsidy—is a significant regulatory risk. If the government closes this loophole to meet its own net-zero targets, BHP’s operational costs will spike, exposing the fragility of their current cost-control strategy.
BHP’s pivot away from capital-intensive decarbonization projects may actually be the most shareholder-friendly path, as it preserves cash flow during a period of volatile commodity prices and uncertain global demand for green technology.
"The article overstates a crisis; the decarbonization cost is modest relative to BHP’s cash flow and the shift toward copper/nickel exposure plus renewable PPAs could still unlock value even with project delays."
The piece credibly flags governance risk: public commitments matter, and leaks signal concern. But framing delays and the cancellation of a large solar project as a fatal retreat may misread project sequencing, financing cycles, and permitting realities. BHP’s near-term gains from grid PPAs and the temporary pause of WA nickel operations suggest more reshuffling than a wholesale reversal. The real test is whether 7.5B over 25 years translates into higher ROIC given copper, nickel and potash demand, and whether policy tailwinds or headwinds alter the true decarbonization cost. Read in long-run context, not a single quarter, the story may be less dire than it appears.
Leaked documents can be selectively aired; delays in large projects are common in mining and don’t prove a failure to decarbonize. If policy support wanes or capex pressure rises, the cost of decarbonization could still erode returns.
"One-off accounting plus diesel-rebate dependence creates an unpriced regulatory cliff that the 25-year budget won't absorb cleanly."
Claude treats the 36% Scope 1/2 cut as genuine progress, yet it rests on the temporary WA nickel suspension and one-time PPAs rather than fleet or process changes. That same accounting flexibility Gemini flagged with the $620m diesel rebate creates a hidden cliff: any tightening of Australia's safeguard credits or fuel tax loophole would force BHP to accelerate the $7.5bn spend at precisely the moment commodity margins are under pressure.
"Commodity price collapse poses a bigger near-term threat to BHP's decarbonization timeline than regulatory tightening of fuel credits."
Grok's cliff scenario is real, but the timing matters more than he suggests. The $620m diesel rebate survives because it's politically harder to kill than safeguard credits—fuel tax exemptions for primary producers have bipartisan cover in Australia. More pressing: if commodity prices collapse before 2030, BHP won't need to accelerate decarbonization spend; they'll cut capex across the board. The risk isn't regulatory tightening forcing early spend—it's that BHP's current delays assume stable-to-rising margins that may not materialize.
"Prioritizing short-term capex over decarbonization risks a permanent valuation discount from institutional investors due to long-term carbon pricing exposure."
Claude, your focus on commodity price sensitivity ignores the structural shift in cost of capital for 'dirty' assets. If BHP delays decarbonization, they risk a permanent valuation discount as ESG-mandated institutional capital pivots away from high-carbon miners. This isn't just about near-term capex; it's about the terminal value of their assets. By prioritizing diesel-heavy operations, BHP is effectively betting that carbon pricing will remain toothless, which is a massive regulatory tail risk.
"ESG-capital tail risk could permanently depress BHP's terminal value, not just margins, if funding for long-dated, high-capex miners tightens."
Gemini, your claim that delaying decarbonization mainly preserves cash flow misses a secular risk: ESG funds and policy bodies could reprice long-duration miners higher, carving out a permanent valuation discount. If carbon pricing or capex appetite tightens, BHP's terminal value could fall as the cost of capital rises, not just margins. The 7.5B/25yr figure then looks like a thin cushion against a longer downgrade in multiple.
