The fuel used for the aircrafts like kerosene and others are often complained of emitting harmful gases like Nitrogen Dioxide into the atmosphere thus leading to an increase of air pollution in and around the regions surrounding the airports. It was however found that reduction of the combustion capacity of the engines led to the increased emission of Greenhouse gases like Carbon Dioxide into the air. Scientists and environmentalists around the world are endeavouring to find means for deriving a sustainable fuel source for the aircraft engines which in turn would reduce the atmospheric pollution (Azapagic and Perdan, 2011, Ch. 15). However it is often held that the endeavour to produce a sustainable fuel for the aeroplanes is not feasible in the technical and ethical sense. It is observed that most of the efforts conducted to produce a sustainable fuel often does not confirm the carbon footprint test and also happens to render increased stress on the engines thus hampering its productivity (Daggett et al., 2007, p.1). Hence the above efforts to produce a sustainable aircraft fuel suffer from lack of technical and ethical feasibility.
Sustainable Fuel for Aircraft Engines
The term sustainability refers to protecting or sustaining the environment in order to meet the needs of the present population without compromising on the needs of the future generation. Sustainability thus concerns a holistic network of environmental, social and economic policies aimed at sustaining the scarce resources. These policies must be measureable and again must also be lend for evaluation to help it met the demand of different periods (Wohlmeyer and Quendler, 2002, p.198).
