Satellite data uncovers gaps, revealing 40% higher methane emissions from Australia’s coal mines

16 Apr 2025

These findings largely support the diverse array of international and peer-reviewed satellite estimates that have identified considerably higher methane emissions from Australia’s coal mines. This includes a recent aircraft study that identified emissions over Hail Creek mine could be 4 to 5 times than currently reported.

Following a year-long national inquiry into methane measurement approaches in Australia, the Federal government has initiated an Expert Panel to provide advice on atmospheric measurement of fugitive methane emissions in Australia and a departmental review on company-led emissions estimates on open-cut coal mines.

These findings highlight not only the critical importance of these reviews, but the urgency in which Australia needs to improve its emissions reporting, especially within its steel-making coal supply chains.

The study encompassed over 90% of Australia’s metallurgical coal production, a large portion of which is presently exported to the EU. This share of exports will soon be subject to strict emissions reporting requirements under the Carbon Border Adjustment Mechanism. Without necessary improvements, these new regulations could jeopardize significant export opportunities.

This discrepancy in emissions reporting points to the risks of relying on self-reported data and underscores the need for more accurate and independent monitoring. 

The study also finds that without major changes to Australia’s existing coal mine methane reporting inventory, the country’s policymakers and international steel-making supply chains will remain in the dark about the total scale of Australia’s coal mine methane emissions.

Australia’s coal mine methane emissions remain under a cloud of international scrutiny. These findings highlight that if we don’t improve reporting, not only could our own emissions accounting be inaccurate, but our international customers can’t know for certain what the scale of emissions lie embedded in their supply chains.

Satellite estimates, including the one generated for this report, all point to the same finding: there is a significant gap between reported emissions and satellite-based estimates. It is crucial to close this knowledge gap to better understand where emission reductions can be made. Given methane’s high global warming potential, improving reporting is essential for identifying and implementing effective mitigation strategies.
