Begging your pardon, but what are you smoking? SO2 and NOX filtration are great, and significantly reduce emissions (~80% seems to be a common figure cited by FGD and SCR manufacturers), but mercury and radionuclide emissions, especially in fly ash, are still a real thing. It also doesn't address the lifecycle problem: we don't really know whether sequestration will work, and you still have to extract and transport the coal itself. As far as I know the investments in coal-process carbon capture have yet to be seriously implemented, which is probably why coal-fired power plants are still responsible for 20% of US CO2 emissions. :-/
