Anthracite burns clean enough to use in a pizza oven. If your neighbor told you he was going to install a new furnace and offered you the choice of it burning wood pellets or anthracite, from a smell standpoint you should absolutely choose the anthracite.
Anthracite, in these regards, is very different from bituminous coal.
Considering the mercury and arsenic in all coal, wood is preferred in ovens.

Yeah, so does wood, which is horribly polluting.
And both are very different from not burning anything.
