Recognition quality of atmospere in towns and in areas with big resource of polluted air.
HRDÝ, Vojtěch
In this thesis, my objective was to determine the amount of air pollutants in cities of Ostrava and Ceske Budejovice and compare the differences of their content in the atmosphere of these locations. The theoretical part deals with the types of pollutants that occur in the atmosphere, their origin, characteristics and their possible toxic effects on the human body and the environment. Furthermore, there is an overview of the methods used for assessing air quality, prevention of air pollution and reducing the level of pollution, so as to reduce risks to human health caused by air pollution, to reduce the environmental burden substance reaching into the air and damaging ecosystems and create conditions for the recovery of components environmental affected by air pollution. To assess the air quality in both locations, I used the method of "secondary data analysis" of publicly available data published by the Czech Hydrometeorological Institute. From these data, I created graphs that compare the air quality in Ostrava in the Ceske Budejovice in the period 15. 8. 2016 - 15. 3. 2017 in all measured categories. For completeness, the work embedded graphs comparing the two cities on the 15th day of the month within a single pollutant. From the results it is evident that these two cities are in many ways similar. The assumption that the city of Ostrava is still a city with the worst air is no longer current.
The carbon footprint of households in South Bohemia
VOŠTOVÁ, Marie
The thesis deals with carbon footprint of households in South Bohemia, namely greenhouse gas emissions associated with the ordinary activities of each of us. The main objective of this thesis is to calculate the carbon footprint of households in the South Bohemia Region. The partial aim is then to assess which of the monitored components has the largest share of the total carbon footprint. These components are heating, electricity, cars, public transport, flying and food. Another partial objective is to compare the results in sociodemographic groups, which are residence, gender, education, age and income per person. The theoretical part explains the concepts such as global warming, sustainable development, ecological footprint, carbon footprint, and three already realized research on carbon footprint. The practical part describes the data acquisition, GILDED project, which was the inspiration for this thesis and method for calculating the carbon footprint. The main part consists of evaluating the calculated results, not overall carbon footprint, but also comparisons within categories of residence, gender, education, age, and income per person. The thesis finishes with the summary, which summarizes the most important results.

Separation and storage of CO2
Odložilík, Martin ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The main objective of this work is to clarify the methods for CO2 capture and storage as an option to limit global warming. The first part is further explained by a phenomenon known as the greenhouse effect, there is illustrated his principle, the effects of climate change, the main factors increasing its intensity and its possible reduction. Framework of the second part is description of the technologies and methods of CO2 capture and storage, the individual steps in these processes and also the possible development in the future. Next chapter discusses the pilot research programs and application of referred technologies to in practice. The last part of this work is devoted to the economical aspect of the problems.
Measurement and evaluation of emissions of gases in the selected operation pheasant and design to reduce them using nanotechnology.
ŠPETA, Ondřej
,,Measurement and evaluation of the production of gas emissions in a selected operation breeding pheasants and their proposal for reduction in the use of nanotechnology " This thesis deals with the production of greenhouse gas emissions in the breeding of pheasants. Greenhouse gases are monitored for fear of global warming of the planet Earth, as they prevent the natural greenhouse effect. Agriculture in its factory farming of livestock is one of the largest emitters, such as: ammonia, carbon dioxide, oxides of nitrogen.
Trading with permits CO2
VROBEL, Radim
In this diploma thesis about the trading of permits CO2 to focus on the issue of release of carbon dioxide in a European context and its control through a system of tradable CO2 - EU ETS. I focus on the first two trading period of the EU ETS, in terms of allocated permits, price trends, and number of permits traded in the two periods in selected EU countries and the Czech Republic. The aim is to determine how appears a system of tradable CO2 permits in selected EU countries and the Czech Republic in the context of fulfillment obligations to reduce CO2 emissions under the Kyoto Protocol. The work compare the situation in the Czech Republic with selected EU countries in selected indicators of specific emissions trading and CO2. The work seeks to determine to what extent the ETS helps in improving the situation of individual countries in absolute production of CO2. The first chapter introduces the issue of climate change. It explains what are greenhouse gases, greenhouse effect and how this effect works. It acquaints readers with one greenhouse gas and that is carbon dioxide. Then the work explains how climate change takes place and there is also described climate history of the Earth, which is necessary to closer understanding of the issue. Then follows the description of international organizations, which deal with climate protection and have international influence. The second chapter focuses on ways to solution climate change. The bigger attention is devoted to the trading with carbon dioxide, than the work explaines the functioning of the European ETS, its development and global influence on the production and reduction of CO2. Than is the chapter devoted to notes and obligations that are promised in the Kyoto Protocol and closer specified the position of the Czech Republic in this Convention. In the third chapter compares the work selected countries of the European Union, which are the largest issuers of the Union's carbon dioxide. If it is possible to compare states in terms of their commitments and reduce CO2 implementation of these commitments. It appears that a large part of the EU Member States fulfill their obligations only partially, and some states it does not meet at all. For some selected countries we can see even an absolute increase in these emissions. Production of CO2 emissions is expressed in the comparison of selected countries in various indicators such as a production of CO2 per GDP or per inhabitant or per hectare of forest. It seems that not all states have aligned their emissions, which are important for sustainable development in that states. The last part compares selected countries in terms of allocated permits in the first and second ETS trading period and describes the evolution of both periods. Finally we performed a detailed analysis of price trends of permits especially in the first ETS period.
