Coal operations are a major source of methane emissions. There are many low-hanging opportunities available to cut down on these, but in general wholesale reductions are more challenging than is the case for oil and gas operations. One of the most effective ways to cut down on coal mine methane is likely to be to cut coal consumption itself.
