Methane can leak from coal mines when sedimentary rocks are crushed or coal seams are exposed. Miners often attempt to drain methane from coal seams before mining the fossil fuel to reduce the risk of explosions and fires. The sector is responsible for about 30% of the total emissions of the potent greenhouse gas coming from the energy sector.
