Key Insights

• BHP has deferred much of the investment required to decarbonise its operations this decade, reducing investor visibility over a credible pathway to net zero by 2050.
• BHP’s actions no longer appear consistent with its ambition to “lead the evolution of [the mining] industry”.^[1] This change in ambition reflects more than technology delays. It has delayed, curtailed or stopped several of its key decarbonisation projects,^[2],^[3] and deferred 87.5% of planned operational decarbonisation spend this decade.^[3:1]
• While BHP has met its modest 2030 operational target largely through renewable power agreements in Chile, only 4% of emissions reductions made have been from Australian operations and there is heavy lifting ahead.
• With no interim targets between 2030 and 2050, BHP lacks a clear accountability framework to guide capital allocation and track delivery towards its 2050 net zero commitment.
• Diesel displacement remains a major decarbonisation challenge. As Australian policy evolves, and rebates for diesel use face increasing scrutiny, BHP may be caught flat-footed if it is not prepared for changing transition economics and policy settings.
• Preparing for transition now – through investing in enabling infrastructure, building workforce capability and preserving optionality to electrify as technologies mature – is critical to reducing cumulative emissions and managing future costs.
• Investors can help drive improvements by encouraging BHP to provide greater transparency about its decarbonisation plans, to adopt a medium-term operational emissions target and to increase accountability for delivery against that target.

BHP has walked back its electrification plans

• There are delays to WAIO electric haul truck and locomotive pathways,^[4] previously expected to be deployed from 2028.^[5]
• There are delays to trolley assist deployment at Escondida and Spence,^[4:1] previously expected to begin in 2029.^[5:1]
• There are delays to renewable electricity investments linked to fleet electrification and inland power demand.^[4:2],^[6]
• A board-approved 50MW solar and 20MW battery project at Jimblebar has reportedly been shelved shortly after approval.^[6:1]
• Planned ~500MW renewable generation and storage projects for WAIO have reportedly been delayed, with no capital funding allocated until at least 2031.^[6:2]
• BHP has purchased new mechanical drive diesel haul trucks^[6:3] and invested in additional gas-fired power generation capacity^[7] at WAIO.
• Battery-electric haul truck trials and pilot projects continue,^[8] but investors have limited visibility on timing and pathways to deployment.

The missing middle: investment is needed now to decarbonise operations toward 2050

• While BHP has achieved its FY2030 operational emissions target early, most emissions reduction to date has been driven through scope 2, contractual measures – primarily renewable electricity procurement in Chile.^[9]
• Capital allocation decisions made in the 2020s are fundamental to future transition costs.
• Diesel displacement via fleet electrification is the big task ahead. Fleet electrification is not a switch that can be flipped in the 2030s. To deploy electric fleets at the pace required next decade, BHP will need to make strategic enabling investments today.
• BHP has attributed decarbonisation delays to "low technology readiness".^[10] However, in any technology scenario, the company should be acting now to maintain optionality to progressively electrify its fleet.
• While BHP has disclosed that major diesel displacement projects have been deferred, it has not disclosed the expected impact of those deferrals on emissions outcomes, cumulative emissions or future transition costs.
• Without an interim 2035 or 2040 target linked to a cumulative emissions budget, investors have limited visibility on whether today’s decisions are consistent with a credible pathway to net zero.

Key stewardship considerations for investors

The following questions should be incorporated into future engagement meetings to better understand the risks associated with BHP’s current strategy:

• Will the company commit to a medium-term operational emissions target, supported by a cumulative operational emissions budget to enable stronger accountability in capital allocation decisions?
• Will BHP disclose its fleet replacement strategy, deployment timelines and implementation milestones?
• How is BHP ensuring that enabling infrastructure, renewable energy investment and operational readiness are progressing in parallel with fleet electrification?
• Will the company align executive incentives and capital allocation frameworks with delivery against post-2030 decarbonisation objectives?
