This is a mind blowing concept. I mean, it makes sense when I read: http://ecoscore.be/en/info/ecoscore/co2 http://ecoscore.be/en/info/ecoscore/co2 But does this take into account catalytic converters or other emissions controls? Cats take the CO from the combustion process and turn it into CO2, the gas you're referencing. I'd just like to clarify because this is a big revelation in my way of thinking about pollution. Are we really releasing that much CO2 post emissions controls?

Emissions controls have no effect at all on CO2 emissions. They don't alter the fundamental stoichiometry of a pure octane combustion: 2C8H18 + 2502 -> 16CO2 + 18H2O So yes, burning a liter of octane (6 moles) will use ~1600 liters of oxygen and emit ~1000 liters of carbon dioxide, or a little over two kilograms. In pure carbon terms, it produces (drumroll) the exact same amount as the input: 49 moles at 12 g/mol or 590 grams.
