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. The dominant adverse environmental result of desulfurization is that removing sulfur from fuel results in increased CO₂ emissions because hydrodesulfurization involves the release of relatively small amounts of CO₂ and consumes additional energy. While a reduction in premature mortalities is relatively confidently predicted, the monetization of these mortalities depends on the approach. An argument for transitioning to an ultra-low sulfur jet fuel is that the health benefits are highly likely and the industry could work to offset the additional 1-8% of increased warming by reducing greenhouse gas emissions. |
