BHP shelved billions in climate projects despite public commitments, leaked documents reveal

Mining giant BHP has quietly abandoned ambitious plans to cut emissions at its Western Australian operations, documents exclusively obtained by the ABC's Four Corners programme and Guardian Australia have revealed.

The leaked internal communications show the company sought to publicly position itself as a climate leader whilst internally deferring major green infrastructure projects by nearly a decade. The revelation comes as Australia's largest mining company faces increasing pressure from investors and stakeholders to deliver on its environmental commitments.

Iron ore profits and emissions responsibility

BHP's Pilbara iron ore operations are critical to the company's bottom line, generating US$14.4 billion (A$22 billion) in pre-tax profits last financial year. These Western Australian mines account for more than one-third of BHP's total Australian emissions, making them the logical focus for any serious decarbonisation strategy.

By mid-2023, the company had developed what appeared to be a genuine commitment to emissions reduction. Internal planning documents outlined an aggressive transition programme featuring electric trucks and trains powered by newly constructed solar and wind farms across the Pilbara region.

From ambition to inaction

However, between mid-2023 and the time of the document leak, BHP fundamentally altered its trajectory. The documents reveal the company has allocated no funding for major renewable energy projects in the Pilbara until 2031—a delay of approximately eight years from initial plans.

More significantly, BHP has committed to continuing diesel truck operations at two major Western Australian mines until the late 2030s, with some operations potentially locked in until 2041. This timeline effectively extends reliance on fossil fuels by nearly two decades beyond current operations.

Public positioning versus internal reality

The leaked communications reveal an apparent disconnect between BHP's public messaging and internal strategy. The company had informed its board that climate action was "urgent" and that delays would pose a significant "risk" to its corporate reputation. Yet despite these warnings, senior management proceeded to defer critical environmental investments.

The documents show BHP has allocated no money to major renewable energy projects in the Pilbara until 2031 and has locked in using diesel trucks at two of its WA mines until the late 2030s and potentially to 2041.

Implications for Australian mining leadership

The revelation poses challenging questions about corporate accountability in Australia's resource sector. As the world's largest mining company, BHP's environmental commitments carry symbolic weight for the broader industry. The company's decision to defer emissions reduction efforts suggests that short-term financial considerations may be outweighing long-term sustainability imperatives.

This development occurs against a backdrop of increasing global scrutiny of mining operations' environmental impact, with institutional investors and international partners increasingly demanding tangible decarbonisation progress. BHP's actions may influence how other major Australian mining companies approach their own climate commitments.

Looking ahead

The leaked documents underscore broader tensions within Australian industry between economic performance and environmental responsibility. As the nation grapples with its climate commitments whilst maintaining its resource export economy, the practices of major corporations like BHP will likely attract continued scrutiny from regulators, investors, and the public.
