Coal is a highly polluting energy source. It emits much more carbon per unit of energy than oil, and natural gas. CO2 represents the major portion of greenhouse gases. It is, therefore, one of the leading contributors to climate change. From mine to sky, from extraction to combustion -- coal pollutes every step of the way. The huge environmental and social costs associated with coal usage make it an expensive option for developing countries. From acid drainage from coal mines, polluting rivers and streams, to the release of mercury and other toxins when it is burned, as well as climate-destroying gases and fine particulates that wreak havoc on human health, COAL is unquestionably, a DIRTY BUSINESS.
It is a major contributor to climate change – the biggest environmental threat we face. It is the most carbon-intensive fossil fuel, emitting 29% more than oil, 80% more carbon dioxide (the main driver of climate change) per unit of energy than gas.
Mercury is a particular problem. According to the United Nations Environment Programme (UNEP), mercury and its compounds are highly toxic and pose a ‘global environmental threat to humans and wildlife.’ Coal-fired power and heat production are the largest single source of atmospheric mercury emissions. There are no commercially available technologies to prevent mercury emissions from coal-fired power plants.
“Clean coal” is the industry’s attempt to “clean up” its dirty image – the industry’s greenwash buzzword. It is not a new type of coal.
“Clean coal” technology (CCT) refers to technologies intended to reduce pollution. But no coal-fired power plants are truly ‘clean’.

DU has become surreal as of late.
But, hey, this will probably be deleted as well.
