The rapid development of aviation industry has caused a lot of problems to the society. The most notable are climatic change and noise pollution. Aviation industry causes climatic change as a result of the hazardous gases and other particulates which pollute the atmosphere. The carbon dioxide and other greenhouse gases lead to acceleration in the rate of climate change and global warming. On the other hand, aircraft noise pollution is generated by its components during the flight. Noise can also be produced by the aircraft during take-off, taxiing, running, from the set exhaust and propeller, or when packed on the ground or en route (Owen & Lim, 2010).
Noise pollution produced by the aircrafts is gaining momentum due to increased number of aircrafts in the world today. They create aerodynamic noises which arise from helicopters tail and main rotors. It can be realized in the form of bluff body or age noise (Kryter, 2004). The major sections which generate them include the propellers, turbine engines, well pits, conditioning systems, and cabin pressurization.
Despite the fact the aircraft noise can lead to impairment, sleep disturbance, hypertension, annoyance, ischemic heart diseases and decreased school performance, it does not pose a great threat to the aviation industry. In this regard, it implies that climate change provides greater challenge to this industry. I would like to argue in favor of climate change due to following reasons.
It has been accepted that aviation industry contributes a lot of problems including diseases, drought, flooding, hunger etc. Aircraft industry contributes to it through the emission of greenhouse gases like Carbon dioxide, Nitric oxide, Nitrogen dioxide, water vapor, and soot. In feet, the emission of carbon dioxide gas by the aircrafts has been estimated to at approximately 20%. Climate change is also contributed by the high-altitude air lines that often fly in the stratosphere. It is an anthropogenic initiative which greatly creates a negative impact on global climate change.
According to official records, between 1990 and 2000, the total greenhouse gas emission from aviation industry was estimated to have increased by 87%. It was attributed to the increased aircraft traffic at the larger airports a long side the expansion of smaller ones. A lot of pressure has been mounted on the aviation industry to address the effects it causes to the aviation industry. The reporting of the intergovernmental panel on climate change (IPPCC) that aviation industry contributes for 3.5% of anthropological climate change has caused great problems to this industry.
Immediate action has been included in the emission trading scheme. Therefore, just like the other players, the investors in this industry will have to set a good portion of their raven up to participate in carbon trading. The money contributed will be responsible for sponsoring environmental cleanliness both in the developed and developing countries. This is because, just like other sectors, aviation has become a chief source of greenhouse gas and radioactive emissions. These are very dangerous gases which is left unchecked, can a negatively impact on global climate (Zerefos et al, 2005).
At the same time, the aviation industry will be taxed. Measures have been put in place to earning tax air travel. It is aimed at complying with the environmental impact Assessment reports which estimate the effects of aircraft on the environment. Therefore, it is supposed that the aviation industry should comply with the United Nations environmental program’s (UNEP) environment regulation standard. It should be coupled environmental ethics which advocates for environmental friendly corporate social responsibility (CSR) programs. The industry must indicate that it is committed to the welfare of the general public by fighting environmental pollution. It should be part of solution to climate change.
The UK government has ruled that the aviation industry should be ready to address its implications on climate in totality. It means that the aircraft stakeholders should not only foams on the effects of carbon dioxide, but also regulate its actions regarding greenhouse gas emissions and radiation effects. There is a lot of pressure on them to increase the efficiency of their aircrafts. The aircraft manufactures should come up innovative and creative ideals to generate more modern jets. They will be environmental friendly because they will enable the industry to tremendously cut down its greenhouse gas emissions to the environment.
Despite its adverse effects to the people, noise pollution from aviation industries has not met stern measures like that of climate change. Several manufactures have come up with mitigation strategies. However, since it become on issue of concern since 1945 many countries have come up with policies to curb the menace. For instance, in the USA government has been committed to ensure that aircraft operators, designers and manufacturers develop improved operating procedures and quieter aircrafts. As a result, quieter designs such as Modern High by Pass turbofan has been produced (Kryter, 2004).
In conclusion, I would like to agree that aircraft greatly impacts or climate change. If stern measures are not taken, IPPC will be right for estimating that the industry will contribute 5% of global warming by 2050. However, since it involves taxations and other financial contributions, the aviation industry will suffer a great blow. In money tamp terms, it will mean financial loss, thus, it will directly affect its expansion. It implies that the implications of the industry on climate have received stern actions from different bodies depending on the intensity of this problem. However, noise pollution has been lighter. Mitigating it means modifying the design of aircrafts to produce environmental friendly machines to meet new standards.
