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.
