Methane is 34 times stronger than carbon dioxide at trapping heat over a 100-year period and 86 times stronger over 20 years; roughly 10 percent of all US methane emissions come from coal mining. Carbon capture and storage technologies (or CCS) are emerging technologies that could allow coal plants to capture some of the CO2 they …

The Global Coal Mine Tracker uses the 0.017 exclusion factor (1.7%) for all coal types, since emissions from coking coal should still be counted in general inventories. When GCMT data is used for a general compilation, it uses 0.017, but when the compilation is relevant to power sector only, it includes 0.645 for coking coal.
