Since fuel consumption and greenhouse gas emissions correlate nearly exactly, U.S. airlines have a financial incentive to improve their environmental performance. According to officials at the Air Transport Association, the national trade group for commercial airlines, environmental performance continues to improve and other initiatives are on deck.
Speaking in a conference call with several aviation bloggers, ATA vice president for environmental affairs Nancy Young identified environmental performance, improving the nation’s air traffic control infrastructure, and energy policy as the airlines’ top policy priorities. The desire for fuel efficiency leads to greenhouse gas emissions reduction, she said: “We couldn’t be more motivated to do the right thing there.” Among these initiatives are alternative, environmentally and food-supply friendly fuels. Young said that it is much harder to develop this kind of fuel for air-based engine units. A 50/50 synthetic blend is currently being tested, she said, with the aim of having 50 percent of the jet fuel supply in alternatives by 2025.
ATA has also adopted an industry-wide goal of improving fuel efficiency by 30 percent by 2025. This can be done, she said, by upgrading fleets, investing in new aircraft (e.g., replacing American Airlines’ MD-80s with B-737s) and enhancing current aircraft (such as fitting them with winglets). John Heimlich, ATA’s chief economist, added that more efficient air traffic control navigation — such as optimal flight paths, continuous descent, and the like — would improve both operational and environmental performance. Heimlich also defended the recent spate of baggage fees as an environmental initative: “When the customer is imposing a fuel penalty on us, as with baggage, we pass that cost on to them.” The airlines are cutting down on fuel use by modifying passenger behavior.
