Cutting CMM this decade is urgent and feasible
This report by Ember argues that reducing coal mine methane (CMM) emissions is an urgent and economically feasible way to slow near-term global warming and improve public health. It highlights that a significant portion of CMM can be mitigated using proven technologies like ventilation air methane (VAM) oxidation and drainage systems, with some measures offering negative net costs.

Why betting on rising demand for met coal in Asia is a losing strategy
The report argues that betting on long-term growth for metallurgical coal (met coal) is a losing strategy as demand plateaus due to China's economic shift and the rise of low-carbon steel production. It highlights the risk of stranded assets given the volume of planned mine expansions and recommends that governments accelerate the transition to green steel through subsidy reform and public procurement.

Solar’s opportunity to reclaim coal’s footprint
This report by Global Energy Monitor (GEM) analyzes the potential for repurposing abandoned and soon-to-be-closed surface coal mines into solar photovoltaic (PV) power plants. It argues that these sites are ideal for solar development due to their existing proximity to grid infrastructure and the need for land reclamation, offering a pathway to align clean energy goals with local job creation and environmental restoration.

Submission to the Clean Energy Regulator: Enhancing Method 2 for Coal Mine Emissions Reporting
Ember's submission to the Clean Energy Regulator argues for the reform of 'Method 2', the compulsory site-specific approach for reporting methane emissions from large open-cut coal mines in Australia. Ember asserts that current implementation is undermined by poor measurement, lack of verification, and transparency gaps, which could distort climate policy. The report suggests that adopting modern stationary and atmospheric measurement technologies, alongside data and verification reforms, could make Australia a global leader in emissions accuracy.

Submission to the Clean Energy Regulator: Enhancing Method 2 for Coal Mine Emissions Reporting
This submission by Ember to the Clean Energy Regulator argues that 'Method 2' for reporting fugitive methane emissions from Australian coal mines is scientifically inadequate and leads to significant under-reporting. The document highlights a growing gap between increasing coal production and stagnant or declining reported emissions, particularly in New South Wales. Ember recommends urgent reforms, including mandated regular updates to emission factors, increased borehole density, independent third-party verification, and the integration of satellite-based atmospheric monitoring to ensure the integrity of Australia's national emissions inventory.

State-level CMM emissions
This report by Ember analyzes coal mine methane (CMM) emissions in Queensland and New South Wales, Australia. It compares officially reported fugitive emissions with satellite-based estimates and airborne measurements, finding that actual emissions in both states are significantly higher than reported, with particularly large discrepancies noted for surface mines in Queensland and overall totals in New South Wales.

Emissions accounting variability
This report examines the discrepancy between satellite-observed methane emissions and company-led estimates from open-cut coal mines in Australia, specifically focusing on the impact of shifting from state-based (Method 1) to site-specific (Method 2) emissions accounting in New South Wales.

Satellite analysis identifies 40% more methane from Australian coal mines
A report by Ember using TROPOMI satellite data and wind-rotation methods reveals that fugitive methane emissions from Australian coal mines are significantly higher than officially reported. The analysis, covering six mining clusters, found that emissions in 2020 were at least 40% higher than national reports, with particularly severe underreporting in New South Wales.

Accounting shift drives emissions reduction
A report by Ember examines a shift in how fugitive methane emissions from open-cut coal mines in Australia are reported, moving from state-based averages (Method 1) to site-specific estimates (Method 2). The report finds that this accounting shift has led to a significant decrease in reported emissions, particularly in New South Wales, creating a mismatch between regulator-compiled averages and operator-reported estimates.

Shift to open-cut Coal Mining and impact on emissions estimate
This report by Ember examines the transition in Australia's coal industry from underground to open-cut mining between 1990 and 2022, highlighting a growing reliance on estimated rather than measured fugitive emissions data.

Underground coal mine closures - a historic win, but future risk
The report examines the role of underground coal mine closures in reducing fugitive methane emissions in Australia. While the closure of 'super-emitting' mines has historically driven significant emissions decreases, new project expansions and license extensions threaten to reverse these gains and undermine national and state climate targets.

Australia’s coal mining emissions paradox
This report by Ember examines the 'paradox' of Australia's coal industry, where coal production increased by 170% between 1990 and 2022 while reported fugitive emissions remained nearly flat. The report attributes this trend to the closure of high-emitting underground mines and a shift toward open-cut mining, which relies on estimated rather than measured emissions. It warns that a transition to site-specific reporting methods has significantly lowered reported emissions, particularly in New South Wales, and that proposed mine expansions could reverse recent emissions declines.

How an accounting shift could conceal millions of tonnes of coal mine emissions
This report by Ember examines the risks associated with a proposed shift in Australia's emissions reporting for open-cut coal mines, moving from state-based average emission factors (Method 1) to unverified company-led estimates (Method 2). The analysis of ten mines suggests that this shift allows companies to significantly under-report fugitive methane emissions, potentially erasing millions of tonnes of CO2-e from the national inventory without actual mitigation.

Submission to the NSW Parliament inquiry into Net Zero
Ember submits that coal mining emissions pose a critical risk to New South Wales' net zero targets. The report argues that current federal regulations like the Safeguard Mechanism are inadequate because they allow offsets over onsite mitigation and may underreport emissions from open cut mines. Using Tahmoor Colliery as a case study, Ember demonstrates that onsite VAM mitigation is technically feasible and commercially viable but requires state-led regulatory pressure. Key recommendations include pausing new coal mine approvals and commissioning a detailed risk report from the Net Zero Commission by June 2025.

Submission to the Review of Australia’s Coal Mine Waste Gas method
This submission by Ember to the Federal Department of Climate Change, Energy, the Environment and Water (DCCEEW) argues for the extension and expansion of Australia's Coal Mine Waste Gas (CMWG) method beyond 2025. Ember recommends extending the methodology to include open-cut mines and improving measurement and verification frameworks to accelerate the decarbonisation of the coal sector.

In The Dark: underreporting of coal mine methane is a major climate risk
This report by Ember analyzes the underreporting of coal mine methane (CMM) emissions, finding that global emissions may be up to twice as high as government figures reported to the UNFCCC. It highlights systemic failures in monitoring, noting that 97% of reported emissions rely on general emission factors rather than direct measurement, and recommends mandatory direct monitoring, satellite verification, and international support for low-income countries to mitigate this potent greenhouse gas.

Risky Millions: Whitehaven’s methane potential
This report by Ember analyzes the methane emissions profile of Whitehaven Coal Limited, Australia's largest pure-play coal company. It argues that Whitehaven's current and proposed mining expansions could release over 1 million tonnes of methane by 2050, while highlighting significant discrepancies between company-reported emissions and independent estimates.
