Introduction
Aviation has a huge environmental impact to the environment and society, the aircraft engines releases a noise that affects human life and the particulates and gases that are released from the aircraft engines contribute to climate change and increases the global warming. Despite the emission reductions from cars and more fuel-efficient and less polluting turbofan and turboprop engines, the rapid growth of air transportation in the recent years contributes to an increase in total pollution attributable to aviation. In the European Union, and increased greenhouse gas emissions from aviation increased by 87% between 1990 and 2006. Like any other form of public mass transportation that relies on resources that are extracted from the planet for e.g. Oil, and the airline cannot be considered sustainable in the long-term too. Because of the limited resources in which the Aviation relies on, it is more realistic to think how to improve the sustainability of the air transportation rather than achieving a sustainable development. Demand for air transport is growing constantly and, if this demand is to be met with all the benefits associated, the community or society must also accept the costs like; (Pollution, Aircraft noise, Environment change, risk, and resources consumption, etc.).
Problems
1. Aircraft Noise
The noise of Aircrafts was historically a major environmental issue for the airline. It is still high on the agenda of public concern. Noise disturbance has a variety of difficult issues to assess because it is open for self- reactions. Its impact is not one permanently on the actual environment, but it can have many effects on the people living in the area of the airport, including: interference in c...

...he oceans. The impact of climate change on CO2 directly and simply depends on its concentration in the atmosphere. CO2 molecules absorb infrared outgoing emitted from the Earth's surface and lower atmosphere. This has caused an increase of 25-30 %, it was observed in the concentrations of CO2 in the atmosphere over the past 200 years of the high temperature. There was a lot of discussion about how it can be achieved and stabilize the concentrations of CO2 in the future.
* Nitrogen Oxides are presented through the atmosphere. N2O are very powerful in the chemistry of the troposphere and the stratosphere, and they are very important in ozone production and in the destruction processes. There are a number of sources (the oxidation of N2O like lightning and fossil fuel combustion) whose contribution to NOx concentrations in the upper troposphere is not well measured.
Climate change is temperature increasing over a long period of time. Climate is imoortant to both humans and ecosyestems in order to thrive. One slight change can disrupt an entire ecosystem. Most people recognize that greenhouse gasses such carbon dioxide have been contributing to climate change. Greenhouse gases are part of earth’s many natural processes. Greenhouse gasses are important to keeping the earth at an overall warm temperature. When When sunlight shines down to Earth, it warms the surface but after so much warming, some of the heat goes right back out into the atmosphere. Some of the heat hits the greenhouse gases. When this happens, the molecules become excited and release even more heat. The issue of climate change has been
One of the major facets of tourism is transportation. The ability for people and equipment to be able to move from one place to another smoothly is not only a convenience but a necessity. Air transportation is one of the largest and fastest growing industries associated with tourism. From passenger travel to food and supply transport there are seemingly ever increasing numbers of flights occurring to help meet the demand. With the increase in flights, comes the increase of pollutants into the air, water, and soil. These emissions, as well as those from the electricity production are linked to acid rain, chemical pollution and global warming. These pollutants have effects not only in populated cities, but also in isolated natural environments as well. S...
In an era of rising technology and increasing population, demands on the environment are continually being pushed to new levels. As a result, it becomes important for us to expand our knowledge about the environment and take appropriate actions to protect this element of most importance to human existence. One component of our environment experiencing some of the greatest abuse due to humans is the air. Air pollution has been on the rise ever since the beginning of industrialization. The climbing number of factories and use of cars worldwide are the major culprits of this environmental hazard. There are various gases released into the air that can be considered air pollutants, but one of the most prevalent and dangerous to the environment is carbon dioxide (CO2). Up to 95% of the CO2 produced is the result of natural processes (Burnett & Matthews Jr., 1998). The rest is a direct result of human activity, primarily through the burning of fossil fuels in the production of energy
Some studies have found “that atmospheric CO2 concentration is approximately 383 parts per million by volume (ppmv), a level not seen in at least 650,000 years, and it is projected to increase by 0.5% per year throughout the 21st century.” (Guinotte) “This is because…the ocean absorbs about a third of fossil fuel emissions, but this amount is likely to increase to 90% in the future.” (Bralower) As a result, “the chemistry of the world's oceans is changing at a rate not seen for 65 million years, with far-reaching implications for marine biodiversity and food security, according to a new United Nations study...” (Knight) “…This change is cause for serious concern [for] many marine organisms…, [because they] may not be able to adapt quickly enough to survive these changes.” (Guinotte)
The Earth’s biosphere is being affected by climate change in numerous ways. The interactions that occur between the hydrosphere and atmosphere are leading to changes in our ocean’s chemistry that could be devastating to humans in the future generations to come. Climate change is the modification in the climate patterns. The effects of climate change have become particularly apparent from the mid to late 20th century onwards and have been substantially contributed to by the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
The present climate change is mostly human induced; the increase in CO2 is mainly because of human activities. Activities like changes in land use pattern, deforestation, land clearing, agriculture, and other activities that have all led to a rise in the emission of carbon dioxide.
For years to come there will always be a speculation on whether the climate change has really taken place or not. Many believe that large companies launched this topic in order to benefit from it in profit, as there are also those who are convinced that this are consequences that have emerged from human mistakes in understanding the environment. As humans are struggling to trust one another whether it is just a big conspiracy or not or environment changing itself, we are slowly starting to feel the effects of climate change. Because of the gasses (CO2) that are in the air, atmosphere is getting warmer, thereby triggering the Greenhouse effect. Almost 70% of emitted gasses in air are CO2, which leads us to believe that this is the main cause of Global Warming. Since it is billions and billions of metric tons per year that are being released in air, many scientists conclude that temperature will most likely be more higher in twenty years from now, than it was in near past.
Climate change is a long term change in the earth’s climate. Climate change is attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. There are 328,000,000 cubic miles of seawater on the planet, covering approximately 71 percent of the earth's surface. Ninety-seven percent of all water is in the oceans. The other three percent is divided amongst the two percent ice and one percent fresh water. Making earth’s waters composed mostly of salt water. Salt water covers most of our planet indicating climate change to have a giant impact on our oceans. Taking a closer look at the ocean and our water in general can reveal several clues to the greater effects of climate change and what other ways climate change can affect our planet. (2)
Well it hasn't for the last 800,000 years. Ice core data shows that the fastest rate of CO2 increase over the last 800,000 years was 30 ppm in 1000 years.
The most destructive human contribution to climate change is fossil fuels combustion, which results in the release of carbon dioxide and other greenhouse gases into the atmosphere. Increased carbon dioxide, methane, nitrous oxide and halocarbons levels in the atmosphere cause an imbalance in the earth’s energy. This is because the gases alter solar radiation and thermal radiation which regulate the earth’s energy. Research indicates that anthropogenic climate change is the cause of the increased global warming over the last fifty years. 57 % of the carbon dioxide emitted is absorbed into the atmosphere while the rest is absorbed into the oceans. Carbon dioxide in the atmosphere is the most central greenhouse gas that is associated with global warming (Eby, Zickfield, Montenegro, Archer, Meissner, & Weaver,
The amount of CO2 in a planet's atmosphere affects the temperature of the planet. As more and more CO2 builds up in the atmosphere, less heat can escape and the planet gets hotter. The CO2 traps radiation from the sun like a greenhouse. This is called global warming or the greenhouse effect. Global warming is becoming a serious problem and CO2 is the major cause. The earth is now warmer than it has been in 1000's of years. The amount of CO2 deposited in the earth's atmosphere from human activities is expected to double by the year 2050. It could possible increase by four in the future with developing countries, such as China, anxious to improve their standard of living.
This identifies the main micro-environmental influences by classifying them into six groups: Political, Economical, Sociocultural, Technological, Environmental and Legal. By applying this framework to Ryanair it is possible to summarise the key forces in the general environment (see appendix A) likely to present opportunities and threats to the organisation (Johnson & Scholes 2002).
Another sophisticated and highly advanced technological advancement, used in today’s world for long distance transportation, is the aircraft. Companies like Airbus, Boeing, Lockheed, Learjet etc. are fighting hard to keep on top of daily technological changes and are doing extensive research on designing and manufacturing energy efficient, low carbon secretion aircrafts. In general, jet engines (both supersonic and subsonic) consume huge amounts of energy and have very high carbon emission rates. For instance, the Boeing 747-400ERF, at maximum takeoff, has a weight of 412,775 kg. To keep this 400-ton bird in the air, at an altitude of 35,000 feet, cruising at a speed of Mach 0.92 (978km/h), the four Pratt & Whitney engines generate about 392,000
Tourism is an industry, with air transport becoming an indispensable factor. One major growing trend in airline industry is market globalization. People travel to other countries for both business and leisure purposes, leading to 7% increment in air travel per year. As a market is globalized, those involved will evolve into global customers who go in search of suppliers running on global base. This leads to a growth in business travel due to the global involvement of companies in terms of investments, production chain, supply and customers. Thus, the participation of air transport in facilitating the world trade is prodigious. Aviation implements another economic benefit of the air transport by providing consumer welfare to individuals while considering the environmental brunt such as the air quality, congestion and noise in the proximity of airports. Air transport being highly demanding has doubled the passenger numbers since the 1980s and over the last decade, it has increased by 45%. The huge growth and development of the aviation field has benefitted in heaps regarding
Climate change is caused due to the release of few carbon compounds into the atmosphere, which drastically brought the weather changes all over the world. Climate change is not confined to a single region. It has become an important issue all over the world for the past few years.
