On a life-cycle basis, aviation/jet fuel has a high carbon footprint. Aviation gas emits 18.3 pounds (lb) and jet fuel 21.1 lb of CO2 per gallon combusted, and flying one mile on average emits 53 pounds of CO2. It directly contributes to climate change and has various negative environmental effects.
