The 787 Dreamliner will provide airlines with unmatched fuel efficiency, resulting in exceptional environmental performance. The airplane will use 20 percent less fuel for comparable missions than today's similarly-sized airplanes.
Boeing 787 Dreamliner Being Designed for Environmental Performance
With the 787 Dreamliner, Boeing is introducing new technologies to create better environmental performance for commercial jetliners.
Fuel Use Reduced
Four key technologies contribute to an impressive 20 percent improvement in fuel use for the 787 Dreamliner as compared to today's similarly sized airplane. New engines, increased use of lightweight composite materials, more efficient systems applications and modern aerodynamics each contribute to the 787's overall performance.
carbon dioxide is produced as a result of fuel consumption. This means that with reduced fuel use comes an equivalent reduction in carbon dioxide emissions.
Another key emission standard for commercial jet engines is nitrogen oxides (NOx). Specific regulations have already been set for future airplane engines, using a complex formula that is based on the thrust ratings of the engines. The 787 is being designed to utilize engines that will be significantly better than the future, more stringent standards adopted by the Committee on Aviation Environmental Protection (CAEP).
Quieter Takeoffs and Landings Delivered
The 787 Dreamliner uses a number of new technologies—most importantly, acoustically treated engine inlets and high bypass ratio along with other special treatments for the engines—to ensure that all sound of 85 decibels (about the level of loud traffic heard from the side of the road) never leaves the airport boundaries. In fact, the noise footprint of the 787 is 60 percent smaller than those of today's similarly-sized airplanes.
Point-to-Point Travel Enabled
Connecting people more directly to their destinations offers a number of environmental benefits. A more direct route uses less fuel, which means fewer emissions. Likewise, fewer takeoffs and landings reduce the total noise footprint.
The 787 is designed to transport passengers and cargo from their city of origin to their final destinations in the most environmentally efficient manner.
Manufacturing Technologies Mean Less Waste
Because the 787 is made primarily of carbon-fiber composite material, which is trimmed like cloth, manufacturing processes will produce less scrap material and waste.
The result will be an overall manufacturing and maintenance process that produces less waste and uses fewer harmful chemicals and agents.
