''"I am an environmentalist, and the reality is that coal is killing the planet as we are using it," Thompson told LiveScience.
The big caveat
Coal can, at least in theory, be burned with little or no carbon footprint, but it requires something called carbon capture and storage (CCS), in which CO2 is separated from the coal (either before or after burning) and buried underground.
The trouble is that CCS has never been tried on a commercial scale, and some environmentalists think that it is only being talked about to provide cover for continued coal use. "'Clean coal' is the industry's attempt to 'clean up' its dirty image - the industry's greenwash buzzword," reads a Greenpeace Web site.'' [source]
