Coal Wikipedia

The largest and most long term effect of coal use is the release of carbon dioxide, a greenhouse gas that causes climate change and global warming. Coalfired power plants were the single largest contributor to the growth in global CO 2 emissions in 2018, 40% of the total fossil fuel emissions. Coal mining can emit methane, another greenhouse gas.
