The Global Coal Mine Methane Review 2026 reports that coal mine methane (CMM) emissions have remained steady at approximately 35 million tonnes despite rising coal production since the 2021 Global Methane Pledge. The report highlights a critical lack of transparency, estimating that 89% of emissions were unreported to the UNFCCC in 2023, and that 87% of global coal production relies on generic emission factors rather than direct measurements. While satellite monitoring is increasing, it currently captures emissions from only 10% of global hard coal production. The report concludes that existing technologies could reduce CMM emissions by 54-63% by 2030, with some measures available at no net cost, and that such reductions are affordable relative to industry profits.
