Abstract:Aircraft emissions can reduce air quality, leading to adverse health impacts including increased risk of premature mortality. A technically viable way to mitigate the health impacts of aviation is the use of desulfurized jet fuel, as has been done with road transportation in many jurisdictions. To attain levels of 15 ppm from the current average levels of 400-800 ppm would increase the cost of jet fuel by 1.6-6.6 ยข/gal, i.e. an increase in the cost of a gallon of just over 1% at 2011 prices. Although the environmental implications are complex, research indicates transitioning to an ultra-low sulfur jet fuel is likely to prevent 1000-4000 premature mortalities per year (if implemented globally), but may increase globally averaged climate warming caused by aviation by 1-8%.
