How much CO2 is emitted from 1 tonne of coal?

Emissions of CO2 can vary significantly by coal type. Using the IPCC default CO2 emission factors of 94600 kg/TJ of 'Other bituminous' coal and 96100 kg/TJ for subbituminous (Indonesian) coals, and then using the McCloskey typical energy contents produces an average emissions factor of 2.4 tonnes of CO2 per tonne of coal.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
