One of the most significant current discussions in sustainable aviation is alternative fuel for airplane, which is a serious argument; however, big question is that efforts to produce a more sustainable fuel to power aircraft are technically and ethically feasible. This paper going to investigate and show there is no alternative fuel to power aircraft in this time. The fuel using by airplane is fossil fuel, which is Jet A1 by burning this fuel there are impact on the global warming the researcher investigate what is the problem with fossil fuel (Jet A1). As solve the fuel problem there are several alternatives have tested, that some of them are biofuel, Liquid Hydrogen, Fracking for Natural Gas and scher-Tropsch (F-T) fuels from fossil feedstocks. However to fund out the alternative fuel is sustainable .firstly defined term sustainability.
There are numerous definitions for the word sustainable. White (2001, p.1) states that sustainability seeks to provide the best outcomes for the human and natural environments both now and into the indefinite future. In addition, Thompson and Sorvig( 2009) in their recent research paper found probably the simplest, widely used definition of sustainability is meeting the needs of today's population with-out diminishing the ability of future populations to meet their needs. The other hand Fresco and Kroonenberg (1992) states that the sustainability of natural ecosystems defined as the dynamic balance between natural inputs and outputs, modified by external events such as climatic change and natural disasters. (Bell and Morse, 2008) the researcher from all research fund out that the sustainability related what is human put the nature has to be try to have balance ever aspect and impact to natu...

...ccessful in aviation industry such as biofuel, Liquid Hydrogen, Fracking for Natural Gas and scher-Tropsch (F-T) fuels from fossil feedstocks. All the fuel has been test and some of the, has been used for long time but the all of the have got impact on environment and social which make unsustainable fuel. At last with those fuels CO2 emissions is not increasing and LH2 approximately putting three times the amount of water in the atmosphere than burning kerosene-type aviation fuel, which is water washes out of the atmosphere a lot faster than carbon dioxide that stays up for years. Fracking presses the water containing the tracking chemicals left underground to fill the spaces in the fractured rocks and may eventually flow into the local ground-water system, making it unsafe for drinking. This research show there is no alternative fuel in this time and technology.
In today's global economy, energy is one of the most crucial and sought after commodities. Who supplies it and how much they supply determines how much influence they have over other countries as well as the global economy. This is why hydraulic fracturing is currently such an important and controversial topic in the United States. Hydraulic fracturing, more commonly known as "fracking" or hydrofracturing, is the process of using pressurized liquids to fracture rocks and release hydrocarbons such as shale gas, which burns more efficiently than coal. This booming process of energy production provides a much needed economic boost, creating jobs and providing gas energy for Americans. The efficiently burning shale gas reduces carbon emission from electricity production plants, reducing carbon footprints on the environment. However, the process of hydraulic fracturing uses millions of gallons of pressurized liquid, which contains toxic chemicals, and some of this water is left over undealt with. The air near fracking sites is often also polluted and unsafe for nearby community residents. Injecting millions of gallons of water laced with toxic chemicals into the rock thousands of feet deep can cause earthquakes, causing a safety hazards for all nearby areas. Hydraulic Fracturing makes rare natural gases easily attainable, boosting the economy and reducing carbon emissions. However, the negative side effects such as contaminated water and air, make hydraulic fracturing a process that may not be worth the benefits.
Ever since the process of hydraulic fracturing—or fracking—made its entrance to the oil industry, issues and problems surrounding the process have become a common occurrence. Fracking is the controversial process of horizontal drilling (see fig. 1), where millions of gallons of water mixed with sand and chemicals are pumped deep into an oil well to extract natural gas from the earth’s crust (Ehrenberg 20). This practice has even been banned in some places (see fig. 1). The methane that comes out of the earth and the water used—called fracking fluid—has the potential to cause problems with local ground water supplies. Whether or not fracking is the cause of these problems, concern should be observed during the fracking process to reduce the chances of water contamination among residential areas.
Although there have been no intensive studies on the drinking water that could be linked to fracturing practices, many people believe it could be harmful to anyone that consumes the water. The EPA and other strong environmentalists are pushing towards more strict regulations on fracking. Contrary to that belief Dr. Charles Goat stated, “drilling for natural gas in itself doesn't pose a threat to air and water quality, if it‘s done properly.” Research has also been done that fracking has little to no impact on the groundwater. Companies also use safeguards to reduce the threat of air contamination from fracking engines and compressors. Local communities and fracking companies work together to reduce noise, traffic, and other environmental factors of fracking. Water is often recycled to use in other fracturing procedures. Fracking companies are working to make fracking less hurtful to the environment and to the local community (Energy from Shal...
Fracking is quickly becoming a debatable topic in our society today. The practice involves injecting fluid into the ground to fracture rock in order to release natural gas. It sounds like it would be a safe way to harness fuels in the earth’s surface, but it actually is a danger to our environment. Because of the dangers of fracking, what little fresh water remains on earth is being contaminated. It is also releasing toxins into the airs creating contaminated air and acid rain. Because of the many health and environmental dangers of fracking, it should be stopped immediately to help prevent more worldwide health issues down the road.
Many people with the term sustainability and have the misconception that environmentalism and sustainability portray the same idea. Although the tree metaphor is an example of nature, the government works in a similar way in terms of economy and society, as it does with the environment. All three pillars of sustainability are the foundations to a successful nation. Likewise, the three roots of the tree must balance to continue to preserve and grow. Overall, sustainability is a crucial concept as it governs all the things we need for our survival and nourishing values. It is how we use our already scarce resources to balance the economy, environment, and society effectively and thrive in the growing
Fracking has become a highly controversial and publicized topic due to rising concerns and growing analysis into the mutual benefits of hydraulic fracturing to retrieve natural gas and oil reserves. With concerns of water pollution, mismanagement of toxic waste and irreversible
When creating a working definition of a sustainable global environment there is a short definition and a long definition. The short of definition of a sustainable global environment is an environment in which all living things can co-exist together while having their essential needs to sustain life met. This definition, while ideal, is probably not realistic due to the fact that humans in many cases are not simply satisfied with living with only the essential needs that sustain life. That leads to the more realistic but complex definition of a sustainable global environment. This definition focuses on sustainability, stewardship, science, political policy and globalization. Sustainability focuses on not depleting needed resources. Stewardship is the moral framework in which our public and private actions are made. The science aspect of a sustainable global environment is the information that decisions, including mandated policy, are made on. The final aspect is globalization, which refers to the interconnectedness humans and the environment share with each other on a global level. Regardless of the definition that is used, the goal is the same, sustaining a high quality of life for all creatures while not exhausting the needed resources to do so.
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.).
Sustainability is when something can be used and not be depleted, destroyed, or damaged past recovery. As we work to live sustainably, we are in effect making use of our resources in a fashion that doesn't eliminate them, and doesn't harm their source. Our resources come from the environment around us and we need to make sure that it is not harmed as we use it. According to the EPA, sustainability stems from a single principle that "Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment” (Sustainability Information). Considering this, it's obvious why we need to make sure we live sustainably and do not damage the source of our resources, our environment.
Throughout history, the concept of sustainability has not been prevalent in the lives of common people. Changes weren 't able to be observed and measured so there was no immediate concern about the topic. With technology and the increasingly demanding pace of living, being sustainable is more important now than ever before. Sustainability is defined as meeting the needs of the present without compromising the ability of the future. Sustainability is made up of many facets that can be overwhelming if learned at once. Focusing on one aspect of sustainability and necessary steps needed to fully achieve it is a very effective method of applying sustainability. In the world today, a growing concern has been the carbon footprint created by aviation.
Sustainability is a concept with a diverse array of meanings and definitions – a widely used glamorous, ambiguous, ambivalent and vague concept that is used by different stakeholder groups in various ways. Presumably to avoid noodling over a terminology or to avoid the confrontation with a definition, most widely the concept is broken down a planning process (c.f. e.g. Döring & Muraca, 2010). That is why most common sustainability is understood as sustainable development.1
Fuel alternatives for the future are very important because, we need resources for life. We won’t have fossil fuels forever. It is important to start now. If we did not have any fuel alternatives how would the world be?
The recent grown in motivation for the study and developing of alternative propulsion systems is in great part of the clearly growth of the air transportation industry and this only means more fuel burning and a higher impact of the aviation industry on the environment and it will take many years until current aircraft are replaced with new gene...
Environmental sustainability is making decisions and taking actions in the interest of protecting the natural world, preserving the capability of the environment to support human life and ensuring that humans use the environment in a way that does not harm the environment. It also questions how economic development affects our environment vice versa.
Sustainability simply defined to me as balancing act between the development of sustainability is necessary for both planet Earth and humans to survive. This is reinforced in the World Commission on Environment and Development report (1987) that sustainable development must meet the needs of the present without compromising the well-being of future generations”. The Earth Charter Organization widened the idea of sustainability to respect for a culture of peace, universal human rights, nature, and economic justice (What is sustainability?, n.d.).
