Sorry..er..this is wrong.
A ton of coal has ~21000000 Btus or 6150 kwh of primary energy in it.
1/3 of that is 2000 kwh per ton of electricity. Most experts use 2000 kwh(electricity) per ton.
Coal is about 60 % carbon so you multiply .6 x 3.66=2.2 tons of CO2 per ton of coal--the EPA uses 2.1-2.3tCO2 and they use .712 tCO2 per Mwh of grid electricity(which is 70% fossil): .7 x 2.1 tCO2/x 2 Mwh ton=7.35 t CO2 per 10000 kwh.
