In 2003, excluding lignite, total of 5,118,800,000 tons of coal was produced around the world.

From <28470 kJ/kg to about 35380 kJ/kg, depending on the kind of coal and how efficiently it is burned. The figures assume 100% efficiency, which is never reached.
2600 tonnes of CO2 is released in 1mw of power generation

Pure coal (?) , None, just CO2.
50% of carbon dioxode is released burnind coal
Around 770007766 Kilajoules is produced from coal even though it is anonymous because it is not 100% efficient even though it's not as reliable.
There is around 2,000 pounds of carbon dioxide waste produced by coal power plants. This is released by a natural gas.

Coal is not all the same. Different coals have different amounts of carbon, Bituminous, or soft coals have the highest percentage of carbon, up to almost 90%, Anthracite or hard coals have close to 80% carbon content, and lignite, brown coals have about 40% carbon content. Carbon content is what determines how much CO2 is produced by coal's combustion.
1 tonne of coal produce 1.83 tonnes of carbon dioxide when burned 1 tonne of coal generates 2.4 MWhours 0.416 tonne of coal generates 1 MWh 0.416 tonne of coal times 1.83 tonnes of CO2/tonne of coal = 0.7625 tonnes of CO2 are produced from 1 MWh of electricity generated by coal
I would say it would be the exact size indicated on the box.
Coal production statistics from the US Department of Energy indicate that in 2007, the US produced (and presumably burned) 1.146 billion tons of coal. China produces and burns slightly more.
1998 was a banner year for overall coal production, which reached a record 1.12 billion tons, according to an estimate from the Energy Information Administration
