How much co2 is in a gallon of gasoline?

A gallon of gasoline produces about 8.89 kilograms (or approximately 19.6 pounds) of carbon dioxide (CO2) when burned. This figure is based on the complete combustion of gasoline, which typically contains about 2.3 kg of carbon per gallon. When this carbon combines with oxygen during combustion, it results in the release of CO2.
