An economic study of a solar collector investment project with specific aspects of energy saving
121-124Views:201The energy saving properi es of an exisi ng solar collector investment has been assessed based on factual data and stai si cal methods. The seasonality of electricity, water and gas consumpi on has been determined. The number of guest nights, the electricity and gas consumpi on showed a strong and a moderate correlai on. The costs saved did not live up to the expectai ons, which makes the return indicators signifi cantly worse. The discrepancy may be due to the system being designed to be bigger than reasonable or the great energy loss as well. The lat er may be because of the distance between the collectors and the hot water containers. The system may have calibrai on problems as well. The whole area brings about saving an amount of energy that equals to HUF 851000, which translates into 8788 m3 of natural gas. The decrease of CO2 emission should come to 16.26 t. on an annual average.

Energy Resources of Unmanned Aircrat Vehicle
92-100Views:247Aviai on is the quickest and most praci cal way of locomoi on, to which people have been paying at eni on for thousands of years. Today – on account of air traffi c, energy crisis and environmentalism – the power source of the aircrat became a key issue. In addii on to fl ight safety, there is a growing emphasis on environmentally friendly operai on. The ineffi cient burning of fossil fuels comes hand in hand with the signifi cant pollutant emission and noise pollui on which bother even those living far from the airports. Nowadays the most important objeci ve of researchers and developers is to create an effi cient, clean and quiet airplane, thus as a new idea they at empt to ui lize electricity in this form on board the aircrat . The ari cle presents some various energy resources through some example of unmanned aerial vehicle.

The impact of increasing environmental expectations and forced paperless administration on corporate sustainability
25-33Views:274Current environmental legislation, directives, and expectations of the stakeholders put increasing pressure on companies' sustainability efforts. Such efforts include applying life cycle analysis methods, resource-saving technologies, low-emission practices, and voluntary ecological rules. Digitization facilitates these efforts, and the forced situation created by the COVID-19 pandemic accelerated the digital transformation process even more. Many companies were pressured to find solutions that legally and effectively bypass personal presence. Paper-based administration was restrained, giving hope for the broader spread of entirely paperless businesses. The study aims to present Hungarian companies' incentives for environmental protection and emphasize how paper-free offices are an essential milestone in sustainable development.

The phenomenon of global climate change and its consequences from a regional and sectoral perspective
103-114Views:183Global climate change poses a significant threat to the planet and our well-being, with carbon emissions being a key contributing factor. The aim of this article is to delve into the complex system of factors influencing carbon emission trends among key countries, examine sectoral differences contributing to such emissions and understand the global actions taken to mitigate the climate change. For this purpose, both quantitative and qualitative research were conducted, and several statistics were used to provide a comprehensive insight on the subject. We have found that while industrialized countries have historically been major contributors to carbon emissions, the rapid economic growth and industrialization witnessed in China and other developing countries mainly in Asia have led to significant increase in their emissions in recent decades. Furthermore, not only regional but sectoral differences could be spotted as the energy sector, where fossil fuels remain a dominant source of energy despite growing efforts to transition to renewable sources, contribute the most to carbon emissions. Lastly, international climate conferences, such as the landmark Paris Agreement, as well as the current energy strategy in EU have sought to mobilize global and regional efforts to mitigate climate change and achieve net zero emissions.

Analysis of practice of sustainability reports
43-52Views:410The responsibility of companies to reduce the negative effects of climate change is obvious. The transition from a traditional linear economy to a circular economy means an increasing burden on companies. Besides the adequate financial performance, more and more emphasis is being placed on environmental performance. This study examines the non-financial sustainability reporting practices of 20 companies listed on the Bucharest Stock Exchange. The analysis used non-financial reports of companies with the highest market capitalization between 2020 and 2022. The analysis results support that the reports of environmentally sensitive companies are more extensive and detailed concerning investigated aspects. The details and length of the companies’ ESG (Environment, Social, Governance) reports increased during the three years examined. The environmental and social aspects of disclosed documents are more detailed for the banks, the oil extraction, and the telecommunication companies. In the company sample examined, it can be observed that most of the reports are prepared according to the GRI regulation. It can also be observed that the companies examined made more detailed and longer reports. The research results also support the fact that the aspects of the ESG report (E, S, G) also depend on the sector in which the companies operate.

The possibilities of companies how to reduce their emmisions
61-68Views:253The sustainability and its key element, the environmental awareness has been known for decades, however in general can be said that in the decision making the short term economic profit is still more dominant both on the individual and company levels. In last few years the rapid growth of CO2 emission is now not just risking the human life but the flora and fauna is in heavy danger. The concerns pay more attention on their short-term profits instead of the environmental protection. First of all with the change of the leadership attitude can reach the environmentally conscious organization that can support the reduction of the emissions, so the improvement of the atmospherical CO2 concentration. In my study I’m going to present what possibilities do the companies have to reduce their emissions and how these improvements could be harmonized with the profit interests (with the reduce of electricity-, water-, and gas consumption).
