Calculation of CO2 weights
 

Where can I find the equation for the calculation of fuel burn into CO2.
As a kid at school, we had to calculate the result of fuel burns - turning fuel into CO2 + H2O, the latter being about 70% of the resulting reaction.
I just want to see how accurate the 'greenies' are in all their calculations.
The future 'carbon footprint' estimates just seem to be excessive to my schoolboy memories.

I think emissions would vary from engine to engine.

Emissions are calculated on sets of empirical observations.
