Ultra-low sulfur jet fuel on the radar - The costs and benefits of introducing ultra-low sulfur fuel for aviation have been weighed up in a new study, and there are unexpected pros and cons. Modelling showed that desulfurising jet fuel would improve air quality, preventing between 1000 and 4000 deaths globally each year. It would cost the global aviation industry $1-4 billion (£0.63-2.5 billion) per year - ¢2-7 per gallon of jet fuel - which equates to an increase in the cost of jet fuel of around 2%. But the study also pointed to climate downsides... Reference: S R H Barrett et al, Environ. Sci. Technol., 2012, 46, 4275(DOI: 10.1021/es203325a)
