Greenhouse Gas Emissions From Coal Mining Activities

2018-1-1  With very significant CO 2, CH 4, and N 2 O emissions from different mining activities as fugitive emissions, coal mining is a major contributor to the buildup of GHGs in the atmosphere. These gases allow solar energy to reach the earth's surface but delay that energy's escape into space, and thus effectively trapping heat in the lower atmosphere.
