BHP Internal Documents Show Limited Emissions Cuts at Western Australia Mines

The documents focus on the Pilbara operations, which account for 30 percent of the company's global emissions. They cite delays in renewable energy rollout and the introduction of electric trucks and trains.

A May 2025 memo stated that solutions are still being sought to achieve net zero emissions. It also noted that delaying climate action into the 2040s risks meeting the 2050 goal. Another document recorded that the decision to retain diesel trucks at one Pilbara mine was inconsistent with greenhouse gas reduction targets.

An internal memo signed by the head of Australian operations discussed risks of material changes in diesel prices if electric equipment is delayed. The company has opposed changes to the rebate. BHP stated that its global emissions have already fallen 36 percent since 2020, largely due to renewable energy conversion at its Chilean copper mines.

The company said it remains committed to its operational emissions target and long-term net zero goal by 2050.
