Environmental Considerations in Aircraft Manufacturing Industry Through the Example of Boeing Andairbus Companies
59-66Views:90Aircraft manufacturing industry has developed dynamically in the last decades. Reinforced polymers have become the most dominant raw materials, while the recycling rate of the generated industrial waste has also increased. The fuel efficiency of the engines has increased, and the emitted CO2 per capita has significantly fallen. However, the environmental impact of the aircraft manufacturing industry seems to reach a permanent level. In this study, we have analyzed the environmental impact and the environmental considerations of the aircraft manufacturing industry through the examples of Boeing and Airbus companies. Our goal was to determine the relation between industrial growth and the environmental impact, particularly to the potential innovations.

Discussion on São Paulo Mobility Plans
17-33Views:138Since urbanization rising and urban demographic increase, urban transportation has been an important life quality aspect and a strategic decision for cities. Mobility seems to follow citizens' behavior and be influenced by urban cultural changes at the same pace it influences back the city routine and resident’s conduct. The discussion around the future of mobility gained new magnitude nowadays since some sort of vehicles have proved themselves as the cause of significant environmental impact, while others showed themselves as alternatives of low impact for different reasons – from quality public transportation to individual transport with minimized emissions. The city of São Paulo in Brazil published its Master Plan in 2014 and its Mobility Plan in 2015, analyzing the current situation and proposing a future for the city’s transportation system. This paper intends to analyze both plans, construe the popular participation in their formulation and application, discuss how data and strategy were presented and whether they are aligned with other countries’ thinking on the subject. As a city of over 10 million inhabitants, in a Metropolitan Region of 39 cities with over 20 million inhabitants, the transportation system of São Paulo is not an easy or single-solution issue. It is known the need for a combination of different transportation modes, requiring likewise new visions for all methods. Owing to the fact that modes complete each other and, in that manner, may reach a wider range of options for the population to plan daily life, then a system with a great variety of modes ensures the best functioning of them all. This paper focuses on an outsider view that searches for answers and solutions on the São Paulo transportation system, having as a base what is considered outstanding in the world for this issue.

Was UEFA’S Goal of an Environmentally Friendly Euro 2020/21 a Success?
152-164Views:489The football Euro 2020/21 has been said to be more environmentally friendly, as it was spread all over Europe, thus no new stadiums needed to be built. On the other hand, more traveling became necessary. How does these effects behave with each other? Was the attempt to reduce emissions successful?
This paper seeks to compare the goals for UEFA 2020/21 for environmental friendliness and its success. A mixed research strategy was adopted in this paper where qualitative analysis was done on existing literature review and also quantitative approach where assumptions were drawn from literature review to estimate the environmental impact. This paper found that UEFA's initial estimate of 425,000 tons of carbon dioxide emissions in traveling for the Euro Cup 2020 was a bit higher than the actual amount of carbon emissions from our calculation of 143,531 tons. What stands out is that its findings agree with UEFA's estimate that Euro Cup 2020 emissions were lower than that of 2016 which emitted 517,000 tons of carbon dioxide for traveling. This gives a greater reason to conclude that UEFA met its goal of reducing carbon emissions. The overall carbon dioxide emissions in traveling and constructing stages were 1,275,988 tons in Euro Cup 2020 and 2,803,000 tons in Euro Cup 2016. This further affirms the overall carbon dioxide emission reduction by half in Euro Cup 2020 as compared to Euro 2016. From our findings, we can conclude that the Euro Cup 2020 indeed succeeded in reducing overall carbon dioxide emissions by half. Despite the success, this paper views that the carbon emissions are still high for a single event and hence there is room for reduction of carbon emissions to lower levels as possible. we can conclude that the Euro Cup 2020 indeed succeeded in reducing overall carbon dioxide emissions by half.

Consumer Perception of Electric Cars in Hungary – Theoretical Considerations and Empirical Results
1-23Views:290Electric cars are becoming increasingly popular in the automotive industry and among consumers; partly as a result of their environmentally friendly characteristics. The aim of the study is to compare the main characteristics of electric and conventional cars in the context of environmental protection. In the first half of the study, we present the life cycle of electric and conventional cars and we compare the overall environmental impact traditional an electric vehicles. We point out that although the operation of an electric car does not pollute the environment locally, the manufacture, charging and disposal of batteries required for operation raises several issues related to environmental pollution. In the second part, we examine the respondents' attitudes towards electric cars based on our own questionnaire research. On the basis of the answers, it can be said that consumers still consider electric cars expensive and are aware that electric cars address some pollution issues to a small extent.

The Impact of Electrical Vehicles on Sustainability: Jordan as a Case Study
393-403Views:168The Global concern is moving toward making a revolution in favor of exploitation of renewable energy in order to improve environment conditions, limit emissions and minimizes consumption of non-renewable resources within the planet. In this context, it is necessary to focus on the transport sector as it contributes of at least 30% of the total primary energy consumption. Therefore, a set of rules must be developed to maintain economic, environmental and social sustainability to address the problems so as not to increase their severity and these cannot be done unless there are joint measures and regulations from governments, companies, manufacturers and users. Unfortunately, the Jordanian transport system mostly depend on the individual transport which supported by cars, and that because of the weak role played by the public transport sector, especially at the capital, Amman. Buying hybrid cars (internal combustion engine + electric motor) and Electrical Vehicles (EV), in the past few years in Jordan is increasing, which is compatible with the global trend to use Electrical Vehicles (EV) instead of Internal Combustion Engine vehicles (ICE) powered by fossil fuels, this issue will have a direct and indirect impact on gas stations companies, also it will have direct impact on labor sector and the current car industry since electric charging stations as well as EV manufacturing is not labor intensive. The main purpose of the study is to show how much it is necessary now to start theoretical assumptions through studying the expected annual increase in passenger cars and its impact on sustainability and predicting the future fuel consumption and emissions and compare them with the base situation.

Sustainability, sustainable supply chain management
322-328Views:777With the rapid development of the world economy, the growing scarcity of natural resources and the degradation caused by pollution, environmental protection has become a major concern for countries and regions of the world. Sustainability is a common subject in many parts of the world and the various research areas among policy makers, journalists, scientists, universities and social debate. It is generally accepted, that companies also play an important role in addressing the challenges of sustainable development. In this role, making a key challenge to balance often conflicting pressures caused by sustainable development, that is, the level of corporate economic performance against environmental deterioration and social disruption. Effective integration of sustainability principles into companies requires action beyond the borders of organizations. The issue of sustainability is becoming more and more prominent in corporate governance. One of the most important area of supply chain management is for companies to gain a competitive edge in the market. This has a significant impact on the natural environment, and there is a growing need to integrate environmental thinking in supply chain management and processes, which is why companies are increasingly focusing on sustainable development, taking on more CSR initiatives and achieving a greener supply chain. Sustainable and green supply chain management practices have been developed over the past decades, trying to integrate environmental considerations into organizations by reducing unwanted negative consequences for the environment of production and consumption processes. In this article, I have examined the issues of sustainability and sustainable supply chain management, mainly based on descriptive secondary literature.

The Impact of Gas Flaring On Man and His Environment and the Way Out
82-90Views:132The nature of flaring processes has created a severe impact on man and the environment. Massive environmental degradation as a result of flaring activities has led to fluctuations in climate as well as depletion of the vegetation cover through acid rain. Findings have been made on some harmful gases released into the atmosphere that have effects on the environment and also on man. In order to control these effects by ensuring a clean atmosphere and environment, a new flaring model (DanMat flaring model) has been suggested. The model uses smoldering mechanism to reduce the amount of heat released into the atmosphere during conventional flaring by 60%. It also uses scavengers to oxidize harmful gas produced during flaring activities into less harmful ones. With this model one can flare gas without polluting the environment since it reduces the emissions of harmful gases during flaring.

CSR Reporting Practices of Hungarian Banks
70-81Views:120The disclosure of information on the exercise of corporate social responsibility (CSR) is the tool most frequently used by companies to promote understanding of the social and environmental performance of an organisation and to improve relationships with stakeholders. For most of the world’s largest companies, reporting on non-financial information appears to be a continuing trend, so it is essential to present the new corporate reporting trends of the 21st century. The disclosure of socially responsible information will be analysed, with a focus on the application of the Global Reporting Initiative guidelines related to CSR. Global Reporting Initiative (GRI) is the best-known framework for voluntary reporting of environmental and social performance by business worldwide. The main objective of the paper is to explore the corporate voluntary disclosure practices of the listed and non-listed banks in Hungary. The extent of voluntary disclosure has significantly improved for decades worldwide, but the situation is not that obvious regarding the Hungarian financial sector. This paper aims to describe the status of disclosure practices of corporate sustainability in the annual reports, sustainability reports or CSR reports of the banking industry in Hungary. Also, increased corporate visibility and financial risk increase stakeholder demand for transparency on the social impact of financial institutions and their CSR practices. Finally, the analysis and subsequent comparison of available CSR reports of banks will be presented.

The Issue of Hidden Hunger
155-164Views:222Mankind faces major challenges in the area of food safety and food security. In addition to the growing population, urbanization, climate change, global environmental change and economic inequality, as well as instability, have a major impact on balanced food supply. According to the WHO (2018) study, not only the elimination of hunger is a problem, but also the increase of our well-being. While 0.8 billion people suffer from a lack of available food, 33% of the global population is overweight, 30% of them are obese. In a long term our growing well-being can also be a great problem. There are three types of dietary problems that coexist in parallel: the hunger and malnutrition, the microelement deficiency, and excessive nutrition and obesity. These three health problems represent a serious burden on public health, which has to be considered in the context of food security and food safety.

Polylactic Acid as a Potential Alternatives of Traditional Plastic Packagings in Food Industry
123-129Views:321Huge quantity of synthetic polymers is used as packaging materials in different fields of food industries. A significant part of these polymers applied as a primary, direct food contact construction. The scoped application area is the sweet industry. In this field Polystyrol (PS), Polypropylene (PP) and Polyethylene terephthalate (PET) have used but during the last fifteen years the usage of PET has been grown. In one hand the price of this material is efficient, form other hand the PET is the one of the most safe (for food industrial applications) petrol chemical plastic that can be used as primary or secondary food contact packaging material. To maximize the customer safety and minimize the environmental impact of traditional PET, a new bio-sourced and bio-degradable alternative polymer aimed to be used in this special food industrial segment. One of the potential alternatives is the Polylactic acid (PLA) that would be a possible substitute as it is compostable and produced from renewable sources and has good physical and mechanical properties [1].

CSR Strategy Creation
344-354Views:671The starting point for the need for social responsibility is to combat the deterioration and destruction of social and environmental values. The social and economic factors induce both society and the economy, including companies, to prioritize their social role. Corporate responsibility needs to be incorporated into the company's strategy so that it can be more planned in the long term, since CSR can thus maximize its impact, ultimately leading to maximizing profits. To be able to develop a strategy, we must first look at the broader environment to which we can apply PEST analysis, by analyzing the social, legal, polo-social and social environment. To take a closer look at the company's narrower environment, we can use the SWOT analysis to identify the company's strengths, weaknesses, opportunities and dangers. Based on these, the Hoshin Kanri method can be used to transform the company's own CSR strategy both short and long-term in order to become part of the corporate culture.

Combustors with Low Emission Levels for Aero Gas Turbine Engines
503-514Views:316The aircrafts are responsible for emitting several types of pollutants, especially the pollutants in the form of NOX, CO2, CO, UHC, SOX and Particulate Matter PM (smoke/soot). The impact of aviation emissions on the global is well known, where these emissions modify the chemical and microphysical properties of the atmosphere resulting in changes of earth’s climate system, which can ultimate in critical changes in our planet fragile ecosystem, also the pollutants produced by aircraft engines cause many health problems. This is why the International Civil Aviation Organisation (ICAO) is seriously seeking to control the emission levels by issuing new standards during the successive meetings of the Committee on Aviation Environmental Protection CAEP (CAEP/01 in 1986, CAEP/2, CAEP/4, CAEP/6, CAEP/8, etc). The new regulations include more stringent standards aimed to reduce emission levels, this led to increased interest in low emission technologies. In this paper, a comprehensive review of low emissions combustion technologies for modern aero gas turbines is represented. The current low emission technologies include the high Technologies Readiness Level (TRL) including RQL, TAPS, DAC and LDI. Also, there are advanced technologies at lower TRL including LPP, ASC and VGC.
