The latest Four Corners / ABC investigation into BHP raises some serious questions for reef conservation. BHP has promoted itself as a "climate leader", including through major investment in reef science and a $27 million partnership with Australian Institute of Marine Science through the Australian Coral Reef Resilience Initiative. The initiative is focused on developing and testing coral reef recovery methods, including coral reseeding, assisted coral recovery, reef soundscapes and other interventions intended to improve reef resilience after bleaching events linked to climate change.
But leaked internal documents reported by ABC suggest BHP’s WA iron ore operations are forecast to cut emissions by only about 1% by 2030, even though those operations account for around 30% of the company’s global emissions. That is hardly "climate leadership".

Reef restoration science has a role, but we need to be honest about its limits. Around the world, coral restoration remains expensive, labour-intensive, and tiny in spatial scale compared with the reef systems now being damaged by climate change. The Great Barrier Reef is 344,000 square kilometers. Coral gardening, larval reseeding and assisted evolution will not offset the increasing frequency of bleaching driven by rising emissions.
The danger here is not just greenwashing. It is opportunity cost. Every dollar and headline poured into high-tech restoration as the “solution” risks pulling attention away from the reef resilience tools we already know work: strong no-take marine protected areas, better fisheries management, and improved water quality.
Restoration may help some small scale tourist sites, but it is not a substitute for protecting reef ecosystems at the large spatial scales at which they function.
Funding reef science is welcome. Using reef restoration project funding to polish the business-as-usual emissions of a mega mining company is simply greenwashing, and it needs to be called out.
