BHP’s Pilbara Decarbonisation Plans Stalled Amid Funding Delays and Diesel Truck Purchases
5/26/2026, 12:18:15 AM
Background & Context
BHP, the world’s largest miner, has pledged net-zero emissions by 2050 and a 30 % cut in its Pilbara iron-ore emissions by 2030—Pilbara accounts for roughly one-third of BHP’s global emissions. Internal “BHP files” reveal that, despite board-approved renewable projects and a beneficiation plant projected to cut 1.7 million t CO2 yr?¹ (the equivalent of removing >350 000 cars), the company has postponed or shelved these initiatives.
Timeline of Key Decisions
- 2022 – Plan to refurbish Jimblebar diesel haul trucks for an eight-year extension, creating a 2030-35 window for electric-truck rollout.
- Mid-2023 – Board signs off a 50 MW solar farm and 20 MW battery at Jimblebar; the project is halted weeks later.
- June 2025 – Beneficiation plant near Jimblebar cancelled; a 500 MW solar-wind-battery scheme delayed, with no capital funding until 2031.
- 2025-2026 – Purchase of 62 new diesel haul trucks (cost > $500 m) for Jimblebar; diesel trucks slated for the proposed Ministers North mine through 2040-41.
- May 2025 – Internal memo labels urgent decarbonisation a “low probability of success” and recommends postponing renewable procurement.
Data & Statistics
- The shelved $1.3 bn renewable project could have supplied up to 70 % of Pilbara’s inland power grid.
- 62 diesel trucks cost > $500 m; BHP consumed 1.23 bn L of diesel in FY 2025 and received $622 m in fuel-tax credits.
- $8 m were spent on carbon offsets for WA operations; BHP reports a 36 % emissions reduction relative to 2020 levels.
Why It Matters
Delays threaten Australia’s Safeguard Mechanism, which requires up to a 4.9 % annual intensity cut, and could impede national 2030 emissions targets. Pilbara supplies >55 % of Australia’s iron-ore exports; higher-grade ore from the cancelled beneficiation plant is increasingly demanded by Chinese steelmakers seeking greener inputs.
Official Statements & Responses
- BHP spokesperson: “No Australian mining operation is currently utilising critical 240-ton battery-electric haul trucks as the technology is not advanced enough to scale to an operational fleet.”
- The company notes a 36 % emissions drop from 2020 levels and highlights ongoing trials of two 240-ton electric trucks and four electric locomotives.
- BHP asserts that “urgent decarbonisation… effectively underpins [its] licence to operate” and that future investment will align with expected carbon-price increases.
Criticism & Opposition
- Tim Buckley, Climate Energy Finance: “BHP is fundamentally putting Australia’s emissions targets at risk.”
- Naomi Hogan, Australian Centre for Corporate Responsibility: “Remaining hooked on expenditure for diesel trucks… demonstrates BHP and Rio Tinto are taking a back seat on decarbonisation.”
- Aaron Morey, Chamber of Minerals and Energy of WA: “There is currently no mining operation anywhere in the world with the scale, complexity and operating conditions of the Pilbara running a fully electrified haulage fleet, because the technology to do so simply does not exist.”
- Analysts note BHP’s diesel purchases contrast with competitor Fortescue’s order of 360 battery-electric trucks.
Conflicting Reports & Gaps
- BHP cites “technology not ready” while Fortescue has secured electric trucks, indicating divergent views on equipment readiness.
- Internal memos project renewable funding only from 2031, yet earlier board approvals targeted first power in 2027, revealing a funding gap of up to four years.
- The claim of a “low probability of success” for the decarbonisation plan conflicts with shareholder-endorsed targets and external expectations for 2030 cuts.
Verbatim Quotes
- “BHP is fundamentally putting Australia’s emissions targets at risk,” — Tim Buckley, Climate Energy Finance
- “The largest source of [direct greenhouse gas] emissions is associated with diesel consumed by heavy haulage and ancillary equipment,” — BHP to the Environmental Protection Authority of Western Australia
- “Aaron Morey, the chief executive officer of the industry group the Chamber of Minerals and Energy of Western Australia, said: “There is currently no mining operation anywhere in the world with the scale, complexity and operating conditions of the Pilbara running a fully electrified haulage fleet, because the technology to do so simply does not exist.” — Aaron Morey, Chamber of Minerals and Energy of Western Australia
- “urgent decarbonisation, in line with BHP's public commitments, effectively underpins [the company's] licence to operate, sustain and grow” — Geraldine Slattery, BHP senior executive
- “Remaining hooked on expenditure for diesel trucks and pointing to technology delays demonstrates BHP and Rio Tinto are taking a back seat on decarbonisation,” — Naomi Hogan, Australian Centre for Corporate Responsibility
- “It said the technology for large haul trucks was "not advanced enough to scale to an operational fleet".” — BHP spokesperson
What’s Next
The internal memo suggests a possible 2030-31 capital release for the 500 MW renewable scheme, contingent on carbon-price trajectories. BHP plans limited electric-truck trials in late 2025 and may revisit diesel-truck procurement after 2027-28. Government reviews of the Safeguard Mechanism and potential tightening of fuel-tax credit limits could pressure BHP to accelerate decarbonisation or face reputational penalties.
