The Aviation Industry Impact The Environment

One of the first things to know about the way the aviation industry impacts the environment is it is different from other sources of emissions. According to a FAA report, aircraft’s btu/passenger mile (energy intensity) is 2,654 in 2012. This is an 24.3% improvement from the 3,505 btu/passenger miles in 2004. It is also improving faster compared to automobiles btu/passenger mile of 8.8% improvement (FAA, 2015). In aviation, most of its pollutants are distributed at high altitudes. However, this can still be hazardous to the environment because aircraft emissions above 3,000 feet can cause up to five times more health impacts than emissions below 3,000 (Steven Barrett, Ian A. Waitz, 2009-2010). A widely studied area in the impacts aviation has is researching air quality. There are two areas which have been getting a lot of attention and becoming more important relating to air quality. The first area is known as fine particulate matter (PM). PM is known as an air pollutant containing tiny particles floating in the air, sometimes creating a foggy, hazy look in the air. Compared to NOx, another compound found in emissions, PM is known to be a greater impact (Waitz, Townsend, Cutcher-Gershenfeld, Greitzer, Kerrebrock, 2004). One challenge the aviation industry is trying to overcome is measuring the PM caused by aircraft and PM caused by outside factors non-aviation related. There are currently no uniformly accepted methods for measuring both the PM and PM precursors from
