Methane emissions from a large coal mine in Australia are considerably higher—three to eight times greater—than what the operator has reported, according to a recent study. The findings are based on aircraft-based measurements conducted in the Bowen Basin, Queensland.
Human-caused methane emissions are a major contributor to global warming. The coal mining industry accounts for an estimated 11% of global methane emissions from human activities, according to the U.S. EPA. However, some experts believe current estimates of methane emissions from fossil fuels are underestimated.
Research Flights Reveal Discrepancy
in the fall of 2023, a research team conducted atmospheric measurements over the Bowen Basin in Queensland.The effort, part of the United Nations Environment Program’s (UNEP) International Methane emissions Observatory (IMEO), aimed to improve understanding of methane emissions from both surface and underground coal mining operations.
The evaluation revealed that methane emissions from a large coal mine in the Bowen Basin were significantly higher than the operator’s reported figures, which are based on nationwide emission factors.
Quantifying Methane Emissions
During September and October 2023, researchers conducted imaging measurements using specialized equipment mounted on research aircraft.Over 40 research flights were conducted to detect and quantify methane emissions from various coal mines. The current study is based on the analysis of data collected during these flights.
One expert noted the importance of connecting atmospheric methane measurements with emission factors for coal, calling it a significant advancement.
Another expert stated that the study marks the first time methane emissions from a single coal mine have been verified using aircraft-based measurements in Australia.
The head of the international observation center for methane emissions from UNEP emphasized the potential for reducing methane emissions in the steel supply chain, stating, This work shows us that we are greatly underestimating the emissions of one of the largest issuers in the region. There is so much potential for the steel delivery chain, its methane emissions and in the To have a real influence on the climate.
Implications for Steel Production
The Bowen Basin is a major coal mining region, with its coal primarily used in steel production. Australia was a major exporter of coal. The study highlights the potential for reducing methane emissions throughout the steel supply chain and the need for better data to understand and reduce emissions in the sector.
Addressing Coal Mine Methane Emissions
Tackling methane emissions in the coal sector presents a significant opportunity for climate action and can also bolster energy security, according to the International Energy Agency (IEA). The IEA notes that several steps can be taken instantly, using existing technologies and tools, to achieve considerable reductions in methane emissions from coal mining.
Experience shows that there are several steps countries can take today – using existing technologies and tools – that can lead to significant reductions in methane emissions from coal mining.

Understanding the Scope of Methane Emissions from Coal Mines
Methane (CH₄) emissions from coal mines pose a significant environmental challenge due to methane’s potent greenhouse gas effects. Both active and abandoned coal mines release methane.
Why Is Methane Emission from Coal Mines a Concern?
Human-caused methane emissions are a major contributor to global warming. The coal mining industry accounts for an estimated 11% of global methane emissions from human activities, according to the U.S. EPA. Methane is a particularly potent greenhouse gas, trapping significantly more heat then carbon dioxide over a shorter timeframe.
Are Methane Emissions from Australian Coal Mines Underreported?
Yes, a recent study revealed that methane emissions from a large coal mine in the Bowen Basin, Queensland, are considerably higher—three to eight times greater—than what the operator has reported. This discrepancy raises concerns about the accuracy of current emission inventories and the effectiveness of reduction strategies. The findings are based on aircraft-based measurements conducted in the Bowen Basin.
How Were Thes Methane Emissions Measured?
Researchers conducted atmospheric measurements over the Bowen Basin in Queensland. During September and October 2023, imaging measurements were conducted using specialized equipment mounted on research aircraft. Over 40 research flights were conducted to detect and quantify methane emissions.
What Region of Australia is Being Studied?
The study focuses on the Bowen Basin in Queensland,a major coal mining region.
What is the Role of the United Nations Surroundings Program (UNEP)?
The research effort was part of the United Nations Environment Program’s (UNEP) International Methane emissions Observatory (IMEO).The IMEO aims to improve the understanding of methane emissions from both surface and underground coal mining operations.
What are the Implications of Higher-Than-Reported Emissions?
Underestimated methane emissions could hinder global efforts to combat climate change. Highlighting the potential for reducing methane emissions throughout the steel supply chain and the need for better data to understand and reduce emissions in the sector.
What is the Relationship Between Coal and Steel production?
The coal from the Bowen Basin is primarily used in steel production. Reducing methane emissions in the coal sector has implications for the steel industry.
Can Methane Emissions be Reduced?
Yes, tackling methane emissions in the coal sector presents a significant opportunity for climate action and can also bolster energy security. According to the International Energy Agency (IEA), several steps can be taken instantly, using existing technologies and tools, to achieve considerable reductions in methane emissions from coal mining.
