Main sources of methane emissions | What's Your Impact

Coal is another important source of methane emissions. In coal formation, pockets of methane get trapped around and within the rock. Coal mining related activities (extraction, crushing, distribution, etc.) release some of this trapped methane. Methane gets emitted from active underground and surface mines as well as abandoned ones.
