This working paper details and analyzes a global, transparent, and geographically allocated carbon dioxide emissions inventory for commercial aviation for calendar year 2018.

This study assesses the fuel efficiency of U.S. airlines on domestic operations in 2017 and 2018. Revenue passenger miles (RPMs) increased 10% and departures increased by 4% from 2016 to 2018. Fuel efficiency in terms of RPMs per gallon of fuel consumed improved by 3%.

This paper estimates the environmental impacts of reintroducing commercial supersonic transport (SST) aircraft into the global aviation fleet. Model the landing and takeoff (LTO) noise, sonic boom, and carbon dioxide (CO2) emissions from a new, unconstrained SST network of 2,000 in 2035.

This report compares the fuel efficiency of 20 airlines operating nonstop flights between the mainland United States and East Asia and Oceania. It extends the previous transatlantic fuel efficiency methodology to the transpacific market.
