Does burning natural gas produce less CO2 per BTU of energy produced than coal?

I think coal produces a higher BTU content but has many other combustion by products that are problematic. Natural gas is cleaner producing mostly Co2 and Water vapor.

Yes. There is a far higher ratio of hydrogen to carbon in Natural Gas so less CO2 is produced for the same BTU's. It does produce more water vapor than coal.

It is not producing more BTU content, but rather contains more BTU content, depending on how you measure them. Since one is a solid and one is a gas, are you going to measure them by mass? volume?
