Study of the ecological impact of production, operation and disposal of various types of cars
Kutnar, Václav ; Jandová, Kristýna (referee) ; Jaššo, Kamil (advisor)
To reduce greenhouse gas emissions, countries have focused on (among other things) automobile transport. However, there are different car powertrains, and each produces a different amount of emissions from different parts of their lifecycles, which also vary from state to state. Knowing exact, comparable values is necessary for deciding how to reduce these emissions most efficiently and economically possible. Existing studies often focus on only one part of the life cycle and/or are not localized to a particular state. This study analyses the entire life cycle of a vehicle and its fuel or energy for a vehicle manufactured, operated, and recycled in the Czech Republic. It draws on existing studies, supplemented by data from state agencies, vehicle manufacturers, and our calculations. It was found that in the Czech Republic, compared to a vehicle with a petrol internal combustion engine (ICEVg), an electric vehicle (BEV) has 33% lower total GHG emissions, and a vehicle with hydrogen fuel cells (FCEV) 19% lower. However, an internal combustion engine vehicle has lower emissions from its production and as a result, its cumulative emissions are lower than an electric vehicle until 70,000 km driven and a hydrogen fuel cell vehicle until 111,000 km

Life cycle assessment of municipal waste
Vlach, Josef ; Slavík, Jan (referee) ; Jícha, Jaroslav (advisor)
The aim of this study is to present methodology life cycle (LCA) and Life Cycle Assessment of disposal the municipal solid waste chain. There is described the procedure of generation of the LCA studies according to the standards ČSN EN ISO 14 040 and ČSN EN ISO 14 044 in the first and second part. In the third part of this diploma there are described LCA analyses that have already been created. The software GEMIS (Global Emission Model for Integrated System) is described in the fourth part. The computer model GEMIS has been used as a calculation tool in this study. The fifth part of this study includes waste management and different kinds of disposal municipal solid waste. In this part is describe basic data about landfilling and incieration. There is shown LCA analysis of disposal municipial solid waste in the sixth part. Data processing was carried out by means of the software GEMIS 4.3. The results were interpreted for incineration and landfilling. Finally there is mentioned results for 1 TJ different elektrical energize to.

Analysis of the external environment for a selected company
FEJTOVÁ, Nikola
The aim of the work is to analyse the external environment of the selected company in two markets with the help of selected analyses of strategic management and questionnaire survey. The selected company is Sodexo, a.s. After that it is designed a strategy for increasing the competitiveness of this company. Methodological procedure: Firstly, it is a definition of basic concepts and individual analyses used for the external environment; then the description of the whole company, an application of individual analyses of strategic management to the selected company; after that the evaluation of the company's position based on the results of questionnaires and analyses; finally, it is a proposal of a strategy for increasing the competitiveness of the selected company.

Emissions Released During the Production of Selected Contact Thermal Insulation Materials
Horenský, Dominik
The topic of the thesis is the study of the influence of selected thermal insulation materials on climate change. Specifically, the amounts of CO2 and SO2 emitted into the atmosphere during the production of these materials are compared. The materials are chosen for contact insulation systems. The input data are from EPD (Environmental Product Declaration) databases that comply with ISO 14025. The aim is to present the production phase of the life cycle of building materials and the importance of their selection for emission reduction. Of the materials analysed, hemp performed best, achieving negative CO2 production and the lowest SO2 production of all, despite its greater thickness. The results can be used for further research due to the input data meeting the ISO standard.

Eco-design: Využití principu posuzování životního cyklu při návrhu sedacího prvku
Šilberská, Klára
The diploma thesis focuses on Ecodesign and Life Cycle Assessment of furniture. Firstly, it introduces the historical origin of ecodesign as well as the standards and regulations of environmental policy. In the next part the ecodesign claims and standards are related to the furniture. The practical part focuses on Life Cycle Assessment of six different bar stools, the research is determined by environmental profiles of stools by using of ecoindicators. The aim of the thesis, prototyping of bar stool, is indicated in the last part of the diploma thesis, where the development of prototype is based on the previous investigation. Furthermore, the environmental profile evaluation of the prototype is also included.
