Illawarra's Methane Challenge – Time to Act Now!
Illawarra’s coal mines have long been recognized for their efforts in capturing methane emissions, but recent reports suggest that progress has slowed at a critical moment for climate action. Methane, a highly potent greenhouse gas, has an immediate warming potential far greater than carbon dioxide, and the underground coal mines in the Illawarra region are significant contributors to its release. While there have been attempts to capture methane as it escapes through ventilation shafts, experts argue that the industry needs to do more—urgently.
Chris Wright, an energy analyst from think tank Ember, has voiced concerns that Illawarra coal mines are no longer leading the way in methane mitigation as they once did. He pointed out that while the Appin mine is planning to introduce a ventilation air methane (VAM) capture system, it is just one step in a much larger challenge. With multiple mines in the region, a single ventilation shaft upgrade is not enough to make a substantial impact on emissions reduction.

Wright emphasized that the technology to capture methane is available, has been tested for nearly a decade, and should already be widely implemented. He believes that mines such as Appin could significantly cut methane emissions—potentially reducing 70 to 80 percent of their emissions—if they fully implemented ventilation and methane abatement measures across all shafts. But this requires commitment from the industry as a whole.
At a recent community forum organized by the Lock the Gate Alliance, Wright discussed the importance of scaling up these efforts. He stressed that while the Appin mine’s initiative is commendable, it’s crucial for other mines, such as Dendrobium and Tahmoor, to follow suit. The NSW government has previously allocated $15 million for methane reduction initiatives, highlighting the need for industry-wide adoption of mitigation measures.
The coal industry has faced mounting criticism for its environmental impact, and tackling methane emissions head-on is an opportunity to regain public trust. Wright suggests that if one major mine sets a precedent with large-scale abatement projects, others may be encouraged to take action. “It’s time for the industry to put their cards on the table and show they are serious about reducing emissions,” he said.
A 2022 study by Ember found that coal mines accounted for 68 percent of Australia’s methane emissions from the energy sector. The report also warned that methane emissions are often underreported and likely to be much higher than officially acknowledged. Given that methane is 82.5 times more potent than carbon dioxide over a 20-year period, the urgency to address this issue cannot be overstated.
Methane abatement is not just a climate necessity; it’s also a strategic move for the coal industry. By investing in emissions reduction, mining companies can demonstrate their commitment to sustainable practices and potentially secure their social license to operate. The time for slow action has passed—Illawarra’s coal mines must step up now to tackle one of the most pressing climate challenges.
