How does coal burning affect the environment?

When coal burns, it releases carbon dioxide and other emissions in flue gas, the billowing clouds you see pouring out of smoke stacks. Some clean coal technologies purify the coal before it burns. Other systems control the coal burn to minimize emissions of sulfur dioxide, nitrogen oxides and particulates.
