Aviation Emissions, Impacts & Mitigation: A Primer FAA Office of Environment and Energy January 2015 Aviation stands out among transportation modes, however, in terms of improving fuel efficiency over the past decade. As shown in Figure 1: Comparison of Vehicle Fuel Efficiency, in 2004, automobiles and airlines operating in the U.S. had very similar energy intensities, with automobiles at 3,496 BTU/passenger mile versus airlines at 3,505 BTU/passenger mile. Between 2004 and 2012, auto energy intensity fell to 3,193 BTU/passenger mile, for an 8.8% improvement. For the same period, aviation energy intensity fell to 2,654 BTU/passenger mile, a 24.3% improvement and is now significantly lower than automobiles. https://www.faa.gov/regulations_policies/policy_guidance/envir_policy/media/Primer_Jan2015.pdf https://www.faa.gov/regulations_policies/policy_guidance/env... In addition to being more efficient flying is wildly safer. You have a 750x better chance of surviving a commercial flight than a car trip the same distance. (2000-2010)
