There has been at least one significant thread discussing this. There was at least one document linked too in that topic with some pretty hard numbers:Anthracite stack emmisions
If I remember correctly the CO2 emissions of anthracite are quite high but other emissions are on par with gas and oil. Lower in some cases. The thing to remember is anthracite contains mostly carbon and doesn't have the volatile matter that bit. coal contains. Wood if I understand it correctly is much worse.
It's something really hard to quantify though, for example people might think they are being green using electric but when its all said and done burning anthracite right in your home is going to be less because more than 50% of the electricity is generated with coal and an inefficient delivery system. People may think wood is clean but those outdoor wood boilers are pretty common now and those are far from green. If I understand it correctly they aren't very efficient especially when burning wet wood which is really common. This produces a prodigious amount of emissions............
