Methods and technologies for carbon dioxide capture in industrial plants
Rek, David ; Máša, Vítězslav (referee) ; Sukačová, Kateřina (advisor)
The rising level of carbon dioxide in the atmosphere has negative effects on life on our planet. Humanity is now dealing with the issue through multinational organizations which attempt to motivate the current industry to develop innovative solutions to increase the energy-efficiency while lowering the amount of produced emissions. The most affected are energy-intensive sectors of the industry, such as the ceramics industry. This diploma thesis is based on a thorough research conducted on scientific literature, mainly scientific articles. The theoretical part is to familiarize one with the issue of rising levels of carbon dioxide. Next, methods to capture, store and use the gas are presented. Furthermore, the thesis focuses on one such method – microalgal bioreactors. The practical past weighs the usability of microalgal bioreactors for the purpose of carbon dioxide emissions capture in a production company LASSELSBERGER, s.r.o. belonging to the ceramic industry. Tubular bioreactor with a volume of 2000 m3 would process 3,75 % of CO2 produced by the core production machine – spray drier, during this process 367,92 tons of microalgal biomass would be produced annually.

Ekonomické a ekologické aspekty elektromobility
Otáhalová, Barbora
The bachelor thesis deals with the dependencies of economic and ecological factors in the field of electromobility in European countries for the year 2021. The literature review characterizes electromobility, briefly describes its development, current status, as well as advantages and disadvantages. Furthermore, a comparison of certain factors between European countries is presented in this chapter. The theory of regression analysis and the stages of econometric modelling are also included in this study. The practical part includes creating and testing two econometric models. The results show that there is a positive dependence between GDP, the number of charging stations and the number of newly registered electromo-biles. Another sub-result is the confirmed dependence of newly registered EVs on the reduction of CO2 emissions.

Hodnocení výstupních parametrů elektomobilů
Diviš, Ondřej
The diploma thesis is devoted to the evaluation of the output parameters of electric cars. In the first part, they are described in detail individual construction solutions of electric cars and hybrid vehicles. Another section deals with the main advantages and disadvantages of individual construction solutions. Furthermore, they are outlined here possible development directions in the field of electromobility. The practical part of the work deals with the measurement of acceleration depending on time and the course of the increase in speed during acceleration in electric cars and vehicles with an internal combustion engine with an automatic transmission. The results showed that electric cars have better acceleration characteristics than vehicles with combustion engines with automatic transmission. In the case of electric vehicles, a linear increase in speed occurs, whereas in the case of internal combustion engine vehicles, an uneven increase in vehicle speed over time can be observed further during the reassignment of individual gears. As part of the evaluation of driving modes, it was also found that all vehicles achieved the best acceleration characteristics in the "Sport" mode.

Vplyv ekonomického vývoja na emisie skleníkových plynov v EÚ
Muchaničová, Júlia
Muchaničová, J. Influence of economic performance on greenhouse gas emissions in EU. Thesis. Brno: Mendel university in Brno, 2023. The diploma thesis focuses on the identification of economic determinants, which influence CO2 emissions and thus also on the fulfillment of the relevant goals of sustainable development. The analysis is created through indicators such as gross domestic product per capita, energy consumption, crude oil prices and foreign trade. The first part of the work deals with an overview of the literature on the given topic. The issue of sustainable development and the relationship between economic growth and the quality of the environment is summarized. The empirical part consists of three chapters. A general model, the Environmental Kuznets Curve model, and also will be created the analysis of the lag of economic growth on the environment.

Living by the river
Malahefji, Tarek ; Kubínová, Šárka (referee) ; Wittmann, Maxmilian (advisor)
The city of Brno is the capital of Moravia in the Czech Republic which was shaped by many historical events, its predominant textile industry was amongst the most important aspects of these criteria, since its main rivers cut through the city (Svratka, Svitava), this industry and its trade, was a main factor in shaping the city as a whole, alongside political conflicts, change of regimes. During the 1960s, after the planned style economy was settled completely, it resulted in big setbacks for the Czechoslovak economy, as the textile industry started to crumble. The final blow to this industry happened after the velvet revolution as privatization took place and most remaining factories were dismantled. This narrative had a big role in shaping how Brno looks today as the northern part of the city is more urbanized than the southern part which is more industrialized by nature, and unlike Prague, these two main rivers are not widely crucial to the public life. This also developed along with other factors a major problem with accommodation quality, price as official data reports increasing dissatisfaction from inhabitants with housing.

Modal Split in Major Czech Cities: Thorough Analysis and Proposal of Policies Leading to Less Car-Dependent Urban Mobility
Bystřický, Vojtěch ; Ščasný, Milan (advisor) ; Šťastná, Lenka (referee)
This thesis focuses on examining the modal split in the five largest Czech cities. Using data from the first nationwide survey on travel behavior in the Czech Republic called Česko v pohybu, the author identifies the main factors which influence the mode choice of inhabitants of Czech cities. The data were evaluated using multinomial logistic regression. Since modal split studies of a large extent are mostly conducted in Western Europe, the United States or Asia-Pacific region, the main contribution of this thesis is to shed some light also on the travel behavior in the Central Europe, more precisely in the largest cities of the Czech Republic. The author analyzes the impact of socio-demographic variables, such as the respondents' age, education level or household income, as well as the importance of the variables related to the trip, such as trip purpose or trip distance. Further, the author also provides comparison of the travel behavior between the examined cities. Among other findings, the author finds that the entitlement to discounted public transport coupons through the ownership of a discount card does not have a significant effect on the probability of using public transport. Further, the results also show that higher education level does not lead to greater use of ecologically friendly...

Analysis of the renewable energy support schemes in the EU: Can be an ECOlogical also an ECOnomical?
Andoková, Senta ; Cahlík, Tomáš (advisor) ; Rečka, Lukáš (referee)
The study compares FIT (Feed-in tariff) and RPS (Renewable Portfolio Standard) as the two most commonly used support schemes for renewable energy sources (RES) in the EU. It examines a relationship of an Environmental Kuznets Curve (EKC) and by a practical experiment for public lighting in Prague the study proposes an ecological functioning of electricity grids in the EU with CO2 emissions reduction effect. The main contribution lies in the recency and originality of the econometric analysis and practical experiment. FIT and RPS analysis demonstrates that both schemes affect demand for electricity and increase its price. The econometric model was tested for 28 EU countries for 1990-2013. The results say that the EU is currently located on the downslope of the inverted U-shaped EKC with a turning point, after which the dependence begins to grow. Nevertheless, for the most of observations the turning point is too far to be a source of concern. Practical experiment has shown that installation of energy saving devices for electricity grids in the EU can bring satisfactory results in reducing CO2 emissions independently of state aid. More efficient use of existing energy sources, however, should rather serve as a complement to conventional support, phasing out with the development of RES technologies....

Does Czech Republic need a carbon tax?
Večeř, Marek ; Špecián, Petr (advisor) ; Máslo, Lukáš (referee)
This bachelor thesis deals with a concept of a carbon tax. It presents the theoretical working of the carbon tax, estimates of the tax rate, possible impacts on the economy and comparison to potential alternatives. In the empirical part of the thesis, there is, based on panel data, analyzed the effect of the size of the carbon tax rate on the amount of emissions of CO2 in selected OECD countries. Results of regression analysis indicate that every increase in the carbon tax rate by $1 per tonne of CO2 will be reflected in the decrease of emissions by 0.57 % in the given country. The thesis thus shows that carbon tax could be quite useful tool for reduction in the amount of emissions of CO2 and therefore a useful tool to reduce impacts of climate change.
