This implies 1 tonne carbon is equivalent to 4.4 tonnes CO2.
Why would you measure a gas in a mass unit? One mole of mass @STP is 22.4L.

You've made two conversions to make one.

Plus not entirely sure what the obsession with weight of "carbon" is, surely it's the volume of CO2 that is the issue. I've never even weighed dry ice.

Only reason to work out a molar mass to volume is to work out partial pressure.
