Ťažký, Tomáš ; Durica,, Tibor (referee) ; Sedlmajer, Martin (referee) ; Nosek,, Karel (referee) ; Kulísek, Karel (advisor)
The disses thesis is focused on usage of secondary raw materials from the electric power industry, specifically fly ash as a component for the building industry, concentrated on concrete. Two main streams are covered, environmental and economical. Reasons, which led to focus on the selected subject are coming mainly from the scarcity and availability of high-quality mineral resources, environmental pressure for usage of industry byproduct, reducing emissions and economical pressure to reduce production cost, especially raw materials. The main purpose of the work was to verify the possibility of increasing the usability of fly ash as a mineral additive in the technology of concrete production with materials retrieved from coal fired power plants and applying mechanical activation of fly ash. The main goal of the experimental part of work was to demonstrate improvement of fresh and hardened concrete properties as a main condition to support economic efficiency of mechanical activated fly ash. Base on previous facts the methodology was covering two main areas, the experimental and the assessment. Relatively large sets of tests were performed, using a wide range of tested high temperature fly ash and fluidized bed combustion fly ash granulometrically treated, by mixing and grinding. Results of the testing confirmed focused parameters for concrete and mortar mechanical properties, total economical efficiency of the targeted solution and the subject of the dissertation. In the experiment section has been retrieved valuable findings contributing to the overall knowledge of the faculty, also for the practical application. The results of the tests confirmed the achievement of the planned target parameters, both in terms of physical and mechanical properties of experienced mortars and concretes, as well as the overall economic efficiency of the proposed design and the topic of the disses thesis. Within the experimental work, valuable professional knowledge and benefits w

Study of the ecology of electric vehicle
Varhaník, Jiří ; Jandová, Kristýna (referee) ; Jaššo, Kamil (advisor)
The first chapter of this bachelor's thesis describes the history of electric cars, their origin, success and decline at the time. The following chapter deals with the clarification of the carbon footprint with regard to the connection to other chapters in the field of ecology of passenger cars. The main goal of this thesis was to study the issues related to the ecology of passenger cars with a focus on electric vehicles in the Czech Republic. The~ecology of vehicles covers all periods of the car's life-cycle, starting with the production, following with utilization, final disposal and recycling of the vehicle. Another goal was to select and describe a suitable methodology for calculating the environmental impact of these vehicles. In the practical part, the relations and calculation methodologies were determined, data sources for individual parameters of these relations were obtained and the calculations were performed. The last part was about processing the obtained data into equations, tables and graphs.

Environmentální zdanění v Evropské unii se zaměřením na automobilový průmysl
Červenková, Pavlína
The diploma thesis focuses on environmental taxation of road motor vehicles in EU countries. Firstly, the thesis deals with negative external effects of transport which are the reason for the existence of the environmental taxes. Secondly, tools used for regulation of negative external effects in the area of environmental protection including environmental tax reform are described. Subsequently, the thesis presents legislation for taxation of road transport in the European Union and analyses the road motor vehicle taxation in the EU member states with regard to environmental aspects. Moreover, the systems of taxation of ownership of road motor vehicles in selected countries of the European Union (Denmark, Italy, Netherlands and Sweden) are described and the levels of taxation of cars and trucks in the Czech Republic and in selected countries of the European Union are compared. The thesis also includes a proposal for taxation of road motor vehicles in the Czech Republic with regard to the environmental impacts of road transport.

Analysis of the link between climate change and food insecurity among small holder farmers: a case study of Mount Darwin district, Zimbabwe
Mufunda, Enoch
Climate change is envisaged to impact the lives of all people on earth in a tremendous fashion regardless of their place of stay, profession or personality. The vagaries of climate change are expected to throw their weight on water balance thereby leading to food insecurity among smallholder farmers in Zimbabwe especially those in Mount Darwin District, the case study of this research work. As such, previous development gains by most African countries are thought to be reversed in the face of climate-related ramifications. My diploma thesis is a culmination of a deeply felt desire to raise awareness on the already existing and potential future impacts of climate change among smallholder farmers in the district as mentioned before. As such, the first chapter provides a situational analysis of climate change and how it has affected agricultural production generally in Zimbabwe. Moving on, the second chapter attempts to review climate change related literature, detailing how greenhouse gases are emitted into the air, how they lead to global warming and subsequently to climate change and so on. Furthermore, the methods of research are interrogated in chapter 3 demonstrating sampling procedures and data collection methods whilst the analysis and interpretation of data is examined in chapter 4. Major findings, recommendations and conclusions of this work are dealt with in the last chapter. Finally, appendices 1 and 2 represent the research instruments that were employed in the form of questionnaires in the data collection processes.

Effort sharing as a legal measure of climate protection
Srb, Jáchym ; Pokorný, Jiří (advisor) ; Sobotka, Michal (referee)
Master thesis "Effort sharing as a legal measure of climate protection" strives to give a comprehensive account of the key characteristics of the effort sharing system, which is one of the two principal EU mitigation tools of the EU. In order to provide a better insight, the thesis first discusses the topic in context of economic theory and international law on climate. The thesis itself is divided into four chapters. First chapter defines the object of climate regulation i.e. greenhouse gases their production and the legal framework of their measuring and accounting.Second chapter focuses on the economic background of climate regulation and it compares different theoretical approaches with existing regulation in force on international and European level. Third chapter gives basic account of the international framework of climate law and specifically on the international mitigation obligations of the EU, which are relevant for the EU law. Fourth and final chapter describes the main aspects of the effort sharing system in contrast to the EU ETS. It draws mainly from the Decision no. 406/2009/ES, which is currently in force and the Regulation no. 2018/842, which will shape the effort sharing system for the 2021 - 2030 period. In four sub- chapters it focuses on the definition of regulated emission...
