Environmental Impact of Aviation For GE117 Michael Adams ITT Technical Institute

Environmental Impact of Aviation Aviation contributes approximately 2 percent of total greenhouse gas emissions, a figure which is projected to grow through 2050. Although fuel efficiency has improved by nearly 16 percent since the 1990s, future technologies—including better flight patterns, more-efficient engines, and alternative fuels—have promise for further emissions reductions. The profitability challenges of the early twenty-first century, however, affect the industry's ability to invest in new technology.

There was growth not only in airport operations and in air travel, but travel to and from the airport. (Environmental Impact of Aviation Operations, 2005) Noise was considered the most serious concern for the airports. Issues with nearby land use was their third biggest concern, which is directly linked to the noise issue because of a federal mandate that noise above a certain level to be incompatible with homes and school use of the land. Considering the future, many of these managers consider air quality to be their biggest concern. The noise issue of reported greatest concern was that aircraft jet engines are still too loud, even with the national standards for quiet engines that have been implemented. This relates to the encroachment of residential areas on the airport. Under federal land use rules, the noise limits for residential and school building from aircraft operation are 65 dB. Yet half of these busiest airports have between 1,000 and 25,000 people living within an area where sound levels reach 65 dB or more. Many noise complaints are still received from outside of this area. Most airports monitor noise levels daily. Noise abatement procedures are required or encouraged, such as ground run-up limitations or restrictions, preferential use of certain flight paths, and limits on uses for certain runways.
