@99.8% of life (Flora) needs CO2 to exist, and we 0.02%(Fauna) need them.
Coal is not "Dirty", "Stinking", or "Ice Cap Melting", especiallywhen the combustion aftermath ~flue is properly dealt with;
Flue Gas Desulfurization ;
Flue-gas desulfurization (
FGD) is a set of technologies used to remove
sulfur dioxide (SO2) from
exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste
incineration, petroleum refineries, cement and lime kilns.
...
Since stringent environmental regulations limiting SO2 emissions have been enacted in many countries, SO2 is being removed from flue gases by a variety of methods. Common methods used:
For a typical
coal-fired power station, flue-gas desulfurization (FGD) may remove 90 per cent or more of the SO2 in the flue gases.

Unfortunately China doesn't do FGD, and there is their "crime".
Coal is "clean" if one does FGD.
