At present, the impact of transport on the environment constitutes a serious problem. This mainly concerns energy consumption and production of greenhouse gases (GHG) that via their participation in greenhouse effect intensification contribute to global warming. In this paper, the calculations provided by the EN 16258: 2012 methodology will be applied to two modes of transport: railway and road transport. Subsequently, the methodology will be applied to a case study of a selected nonelectrified railway line in comparison with parallel road transport. In particular, energy consumption and production of greenhouse gases will be monitored depending on traveling the distance between selected cities in the Czech Republic.

Today, the environment, optimizing energy consumption and sustainable development have become the most important issues at the international level. Increasing population growth has disastrous effects on Earth's natural habitats and issues such as general global warming, increase in greenhouse gases in the atmosphere that cause global warming, air, water and soil pollution all lead to irresponsible consumption of energy. This paper tries to evaluate sustainable patterns in warm and dry areas that with the climate analysis and contemporary comparison of design in hot and dry climate while clarifying various aspects, explain the impact of environmental factors in the formation of sustainable architecture and the use of applied patterns to design a sustainable architecture. It have been used analytical method, as well as library and documentary research in this study.

The article aims to determine the difference in the perception of selected business risks and their impact on the future of business concerning the entrepreneur’s experience with business bankruptcy. The case study involved 73 small and medium-sized enterprises (SMEs) with experience of business bankruptcy and 381 SMEs without the experience of business bankruptcy from the Czech Republic (CR). Linear regression models were used to verify statistically significant causal relationships between selected indicators of the most significant business risks and respondents’ perceptions of the future of business. The results brought interesting findings. The attitudes of entrepreneurs show that personnel, market, and financial risk are among the three most significant business risks. Experience with business failure is not a significant factor in determining the impact of market indicators on the business’s perceived future. The adequacy of sales of services and products has the greatest impact. The experience of the bankruptcy of SMEs is important in financial risk attitudes. According to entrepreneurs who have no experience with bankruptcy, the perception of financial performance has the greatest direct impact on the future of business. Conversely, for entrepreneurs who have experienced bankruptcy, the ability to properly manage financial risk on the company’s future has the greatest direct impact.

Floods are natural events with extensive impact on property and life of affected people. They significantly came in 1997 into the life of Czech society and since then has caused damage almost 172 billion CZK. The paper focuses on the assessment of impact of floods from 1997 to 2010 on economic level of each region. The impact is assessed on basis of development of the basic macroeconomic indicators such as GDP and economic level of regions, change in fixed capital formation, sales of industrial products and unemployment. The basic idea is to show how much floods have influenced region’s economy and if it depends more on the amount of flood damages or nature of damage (structure within infrastructure). 13 regions of the Czech Republic except Prague were chosen for the analysis. Prague was excluded from the analysis because of its specific status (capital city and the region) and economic conditions among regions in the Czech Republic (higher GDP per capita than the national average).

This chapter focuses on the case study of China, which is facing grave issues regarding environment and global warming. Hence, the “Airpocalypse” in China led to need and debate about the sustainability of the environment. In this chapter, an effort has been made to analyze the environmental sustainability risk which the country of China can have for the increasing rate of global warming, and how this part of region can have a transnational impact on other neighboring countries when it comes to the cause of making environment pure from pollutants, carbon dioxide, and coal emissions. The methodology of this research is qualitative, descriptive, and analytical in nature. This chapter includes the variable of environmental sustainability which is dependent on the energy consumption of industries of China involved in emission of greenhouse gases.

Abstract An administrative fine is a monetary penalty that may be imposed by a supervisory authoritity as an administrative punishment. Such a fine adversely interferes in the cash flow generation of the company in question. The fine can be described as an investment carrying opportunity costs with no economic returns. However, according to the judgment of the Constitutional Court of the Czech Republic Pl. ÚS 3/02 of 13 August 2002 it is submitted that the fine cannot be imposed in such an amount that would ultimately be liquidating for the sanctioned entrepreneur. The assessment of whether the specific amount of the fine imposed represents such an intensive interference with the entrepreneur's property that his business activity becomes pointless (i.e., in the long run only for the payment of a fine) is elaborated in this article. Based on a case study from the Czech Republic, this article deals with an example of a suitable methodological procedure, on the basis of which it is possible to evaluate the impact of a specific amount of fine imposed on the property of a sanctioned entrepreneur and assess ex ante whether (i) continuity of his business will be interrupted in the future, i.e., when, as a result of the payment of the fine, he eventually goes bankrupt in the form of insolvency or over-indebtedness and / or (ii) his business activity will only serve to pay the fine and thus become "pointless". The presented economic narrative and methodology are relevant for policy makers and, particularly, for supervisory authorities imposing the fines or assessing the requests for remission.

The main purpose of this paper is to assess energy consumption with a breakdown into main sectors of the countries that belong to the Visegrad Group. The specific objectives aim to determine changes in energy absorption, its productivity, structure by sectors and to show the similarities of the Visegrad Group countries to the other EU states in terms of the sectoral energy absorption structure. All members of the Visegrad group, i.e., Poland, Hungary, Slovakia and the Czech Republic, were purposefully selected for the study as of 31 December 2018. The research period covered the years 1990–2018. The sources of gathered information were the literature on the subject and OECD data. The following methods were used for the analysis and presentation of materials: explanations, tabular and graphical depictions, descriptive statistics, dynamics indicators, and cluster analysis performed with the following methods: k-means, hierarchical agglomerative clusters and DIvisive ANAlysis (DIANA). There is a limited number of previous studies on the relationship between the national level of economic development and energy consumption in different sectors of industry. Additionally, there are no such analytical projects concerning EU states. The article fills the research gap in this area. It was established that the dynamics of productivity growth over the nine years (2010–2018) was similar in the countries of the Visegrad group and on average for the EU. This means that the members of the Visegrad group did not actually improve their energy efficiency as compared to the EU average. The reason may be the increasingly faster implementation of modern technologies in developed economies of Western Europe as compared to the developing countries, which include the members of the Visegrad group. The conversion of the economy had a very large impact on changing the structure of energy absorption by sector. Industry and agriculture lost their importance. On the other hand, the transport and service sectors benefited. As a result of the cluster analysis, all EU (European Union) states were divided into four groups. Poland, the Czech Republic, and Hungary found themselves in one group, along with most Western European countries. This may mean that the economies of these states have become unified with highly developed economic systems. Slovakia found itself in the group of states with a greater importance of industry. The study complements the contribution to the theory. From a practical point of view, it shows the impact of economic transformation on changes in energy consumption in individual sectors, which may be a model of transition in this area.

The paper deals with the subject Transition economy and happiness – a case study of the Czech Republic in a comparison with The Netherlands in the 1990- 2004 period. The paper addresses the following two questions: 1. How has the level of happiness changed since 1990 in the Czech Republic and in The Netherlands? 2. Are there differences with respect to variables that explain differences in happiness between both countries. It appears that. at the beginning of the 1990s of the last century, the Czechs were less happy than the Dutch and, that, people in the Czech Republic were less happy in 1999 than they were in 2004. Furthermore, Happiness in the Czech Republic is approaching the level of happiness in The Netherlands. In both countries happiness is positively affected by subjective health status, perceived freedom of choice over life, being married or living together and satisfaction with one’s financial situation and having trust in social institutions. But there are differences with respect to the impact of age, education and religion .

Abstract Transport is one of the human activities that increases the amount of greenhouse gases in the air. CO2 is the main cause of global warming and contribute for around 80 % of all greenhouse gas emissions. The paper presents CO2 production based on the amount of sold fuel in Slovakia and Slovenia. Based on the obtained data, the calculations about the production of CO2 according to the type of fuel was made. The conducted research has focused on the issue of traffic congestion and to reduce CO2 emissions by 15 % in total by 2030, as Slovakia and Slovenia concluded an agreement with other EU members in 2009. External costs calculation was made with average price of 1 tonne emission credit in 2016 and with presumed average price in 2019. The case study takes into account the consumption of the gasoline and diesel in transport throughout all Slovakia and in Slovenia.
