The 747-8’s new wing design and engines, and the resulting improved cruise performance, make the airplane environmentally friendly. The 747-8 reduces carbon emissions by 16 percent compared to the 747-400 and is 16 percent more fuel efficient. It also has a 30 percent smaller noise footprint and operates at 52 percent below the International Civil Aviation Organization (ICAO)’s Committee on Aviation Environmental Protection (CAEP)/6 limits for nitrous oxide. The 747-8’s noise reduction makes it more versatile for operators because it can operate longer at noise-sensitive airports than the 747-400.
