2008 Environment Report Boeing
Air Transportation Systems

Our efforts to have a positive impact on the environment go beyond our products. Improving the efficiency of the global transportation system can also provide significant environmental benefits. In fact, the International Air Transport Association (IATA) estimates that air traffic management enhancements could improve fuel efficiency and CO2 emissions by up to 12 percent.

Boeing recognizes that air traffic management improvements provide the greatest short-term opportunities to improve environmental performance of the transportation system. That's why we are working with industry, regulators, airlines and airports to improve management of the air space and ensure efficient, safe and seamless operation around the world.

Our work includes the development of air traffic management solutions that reduce fuel use by minimizing delays and holding patterns over airports and capitalizing on precision navigation technologies in modern aircraft often left unexploited in the legacy system. One example: our Tailored Arrival concept increases airplane arrival efficiency by establishing a predictable continuous descent rather than the current step-down descent, resulting in reduced fuel use, emissions and noise. Trials have demonstrated that implementing these types of advanced arrival techniques can save up to 500 gallons of fuel per flight.
