Kg of carbon or CO2?

by J. Sireyjol

In each carbon dioxide molecule, we have to count the mass of of carbon (C) and 2 atoms of oxygen (O). Counting carbon only is easier!
On a chemical point of view, 1 liter of gasoline contains approximately 0.7Kg of carbon, which is close to 1Kg.
But if you take into account the amount of carbon that is needed to extract the corresponding amount of oil, to refine it and to bring it to the gas station -and you could add the carbon needed to maintain your car-, it is a good approximation to say: 1L of gasoline (any type) = 1 Kg of carbon.
The Kg of carbon is the unit used by the ADEME (Agence de l’Environnement et de la Maitrise de l’Energie). It is also the way emissions of other greenhouse gases are made comparable to CO2 emissions, through the unit of "carbon-equivalents" (methane, nitrogen dioxide...).
